Windows locale error unsupported locale setting

[This answer is target on linux platform only]

The first thing you should know is most of the locale config file located path can be get from localedef --help :

$ localedef --help | tail -n 5
System's directory for character maps : /usr/share/i18n/charmaps
                       repertoire maps: /usr/share/i18n/repertoiremaps
                       locale path    : /usr/lib/locale:/usr/share/i18n
For bug reporting instructions, please see:
<https://bugs.launchpad.net/ubuntu/+source/glibc/+bugs>

See the last /usr/share/i18n ? This is where your xx_XX.UTF-8 config file located:

$ ls /usr/share/i18n/locales/zh_*
/usr/share/i18n/locales/zh_CN  /usr/share/i18n/locales/zh_HK  /usr/share/i18n/locales/zh_SG  /usr/share/i18n/locales/zh_TW

Now what ? We need to compile them into archive binary. One of the way, e.g. assume I have /usr/share/i18n/locales/en_LOVE, I can add it into compile list, i.e. /etc/locale-gen file:

$ tail -1 /etc/locale.gen 
en_LOVE.UTF-8 UTF-8

And compile it to binary with sudo locale-gen:

$ sudo locale-gen 
Generating locales (this might take a while)...
  en_AG.UTF-8... done
  en_AU.UTF-8... done
  en_BW.UTF-8... done
  ...
  en_LOVE.UTF-8... done
Generation complete.

And now update the system default locale with desired LANG, LC_ALL …etc with this update-locale:

sudo update-locale LANG=en_LOVE.UTF-8

update-locale actually also means to update this /etc/default/locale file which will source by system on login to setup environment variables:

$ head /etc/default/locale 
#  File generated by update-locale
LANG=en_LOVE.UTF-8
LC_NUMERIC="en_US.UTF-8"
...

But we may not want to reboot to take effect, so we can just source it to environment variable in current shell session:

$ . /etc/default/locale

How about sudo dpkg-reconfigure locales ? If you play around it you will know this command basically act as GUI to simplify the above steps, i.e. Edit /etc/locale.gen -> sudo locale-gen -> sudo update-locale LANG=en_LOVE.UTF-8

For python, as long as /etc/locale.gen contains that locale candidate and locale.gen get compiled, setlocale(category, locale) should work without throws locale.Error: unsupoorted locale setting. You can check the correct string en_US.UTF-8/en_US/....etc to be set in setlocale(), by observing /etc/locale.gen file, and then uncomment and compile it as desired. zh_CN GB2312 without dot in that file means the correct string is zh_CN and zh_CN.GB2312.

When running a Python script, you may encounter the «unsupported locale setting» error, which typically appears as follows:

locale.Error: unsupported locale setting

This error occurs because the locale settings of your system are not supported by Python’s locale module. The locale module uses the locale settings to perform locale-aware operations, such as formatting dates and times, currency, and sorting strings in a specific language-sensitive order.

Method 1: Set the locale environment variables

If you are facing the «unsupported locale setting» error in Python, it means that your system does not have the required locale settings installed. One way to fix this issue is by setting the locale environment variables. Here’s how you can do it:

  1. Import the locale module:
  1. Set the locale environment variables:
locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')

Here, we are setting the locale to en_US.UTF-8. You can replace this with the locale that you want to use.

  1. Verify the locale:
print(locale.getlocale())

This will print the current locale settings. You should see the locale that you set in step 2.

  1. Use the locale module in your code:
formatted_number = locale.format_string("%d", 123456789, grouping=True)
print(formatted_number)

Here, we are using the locale.format_string method to format a number with grouping (thousands separator). This will use the locale settings that we set in step 2.

That’s it! You have successfully set the locale environment variables in Python. Here’s the complete code:

import locale

locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
print(locale.getlocale())

formatted_number = locale.format_string("%d", 123456789, grouping=True)
print(formatted_number)

Method 2: Install the missing locale

To fix the Python locale error «unsupported locale setting», you can try installing the missing locale. Here are the steps to do it:

  1. Check the current locale settings by running the command locale in the terminal. You will see a list of locale settings, such as LANG, LC_ALL, LC_CTYPE, etc. Take note of the current settings.

  2. Identify the missing locale. The error message usually indicates which locale is missing. For example, it could be «en_US.UTF-8» or «de_DE.UTF-8».

  3. Install the missing locale by running the following command in the terminal:

    Replace <locale> with the missing locale, such as «en_US.UTF-8» or «de_DE.UTF-8». This command generates the locale files for the specified locale.

  4. Update the locale settings by running the following command in the terminal:

    This command updates the system-wide locale settings based on the current values of environment variables.

  5. Verify that the missing locale is now available by running the command locale -a in the terminal. You should see the missing locale in the list of available locales.

Here’s an example code snippet that installs the missing locale «en_US.UTF-8»:

$ locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

$ sudo locale-gen en_US.UTF-8
Generating locales (this might take a while)...
  en_US.UTF-8... done
Generation complete.

$ sudo update-locale
Generating locales (this might take a while)...
  en_US.UTF-8... up-to-date
Generation complete.

$ locale -a
C
en_US.utf8
POSIX

In this example, the missing locale «en_US.UTF-8» was installed successfully and is now available in the list of available locales.

Method 3: Use a default locale

To fix the Python locale error «unsupported locale setting», you can use a default locale. Here are the steps to do it:

  1. Import the locale module:
  1. Set the default locale using the setlocale() function. This function takes two arguments: the first argument is the category, which specifies the type of locale to use (e.g. LC_ALL, LC_CTYPE, LC_NUMERIC, etc.), and the second argument is the locale to use (e.g. «en_US.UTF-8», «es_ES.UTF-8», etc.). In this case, we will set the default locale to «C»:
locale.setlocale(locale.LC_ALL, 'C')
  1. Now you can try running your Python program again, and the locale error should be resolved.

Here is the complete code:

import locale

locale.setlocale(locale.LC_ALL, 'C')

Note that setting the default locale to «C» may not be appropriate for all situations. You may need to set the locale to a different value depending on your specific needs.

Method 4: Change the default locale for Python

If you are getting a «unsupported locale setting» error in Python, you can fix it by changing the default locale for Python. Here are the steps to do it:

  1. Import the locale module:
  1. Set the default locale to a valid one. For example, «en_US.UTF-8» for English language and UTF-8 encoding:
locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
  1. Test if the default locale is set correctly by printing it:
print(locale.getlocale())
  1. If you get a «locale.Error: unsupported locale setting» error, it means that the locale you set is not available on your system. You can check the available locales by running the following command in your terminal:
  1. Choose a valid locale from the list and set it as the default locale:
locale.setlocale(locale.LC_ALL, 'fr_FR.utf8')
  1. Test again if the default locale is set correctly:
print(locale.getlocale())
  1. If you want to change the default locale permanently, you can add the following line to your ~/.bashrc file:
export LC_ALL=en_US.UTF-8
  1. Save the file and run the following command to reload it:
  1. Now you should be able to run your Python code without getting the «unsupported locale setting» error.

Here’s the complete code:

import locale

locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')

print(locale.getlocale())

locale.setlocale(locale.LC_ALL, 'fr_FR.utf8')

print(locale.getlocale())

I hope this helps you fix the «unsupported locale setting» error in Python. Let me know if you have any questions!

hi @LoveBootCaptain ,
i saw your project by twitter, and at the same i see this project here.i’m a beginner in python,too. So i try to build this project. And i encounter an error:

Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\WeatherPi_TFT-master\WeatherPi_TFT.py", line 16, in <module>
    locale.setlocale(locale.LC_ALL, locale.getdefaultlocale())
  File "D:\Python35\lib\locale.py", line 594, in setlocale
    return _setlocale(category, locale)
locale.Error: unsupported locale setting

i dont know where is wrong.However,i annotate return _setlocale(category, locale) in «D:\Python35\lib\locale.py», line 594
and the error is gone
But there is a new error:

    obj, end = self.scan_once(s, idx)
json.decoder.JSONDecodeError: Expecting property name enclosed in double quotes: line 3 column 1 (char 59)

i have no idea about it…

PS: i can get defaultlocale by locale.getdefaultlocale():

>>> locale.getdefaultlocale()
('zh_CN', 'cp936')

Do you have a idea?

Answer by Calum Campbell

This error can occur, if you have just added a new locale. You need to restart the python interactive shell (quit() and python) to get access to it.,To install a new locale use:,This file can either be adjusted manually or updated using the tool, update-locale.,run locale-gen to generate newly added locales

Run following commands

export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
sudo dpkg-reconfigure locales

While you can set the locale exporting an environment variable, you will have to do that every time you start a session, meaning after a restart, things would go back the same as before. Setting a locale the following way will solve the problem permanently.,You’ve been fiddling with the environment variables then try to use pip,The root cause is: your environment variable LC_ALL is missing or invalid somehow,If you want to solve it quick, you can sequentially run the commands below in the terminal :

this means the environment variable LC_ALL is missing or invalid somehow.,LC_ALL is the environment variable that overrides the value of the LANG and the values of any other LC_* environment variables.,If you see the following error while installing pip:

Answer by Drew Knight

Note that this function will not work with the ‘C’ locale, so you have to set a
locale via setlocale() first.,If the given encoding is not known, the function defaults to the default
encoding for the locale code just like setlocale().,The locale module defines the following exception and functions:,If locale is omitted or None, the current setting for category is
returned.

import locale
locale.setlocale(locale.LC_ALL, '')

If you see the following error while installing pip: 

Traceback (most recent call last):
     File "/usr/bin/pip", line 11, in <module>
       sys.exit(main())
     File "/usr/lib/python2.7/dist-packages/pip/__init__.py", line 215, in main
       locale.setlocale(locale.LC_ALL, '')
     File "/usr/lib/python2.7/locale.py", line 581, in setlocale
       return _setlocale(category, locale)
   locale.Error: unsupported locale setting

this means the environment variable LC_ALL is missing or invalid somehow.

FIX :

run the following command:

and retry installing again.

What is LC_ALL?

LC_ALL is the environment variable that overrides the value of the LANG and the values of any other LC_* environment variables.

In a script, if you want to force a specific setting, as you don’t know what settings the user has forced, your safest and generally only option is to force LC_ALL.

The C locale is for computers. In the C locale, characters are single bytes, the charset is ASCII, the sorting order is based on the byte values, the language is usually US English.
You generally run a command with LC_ALL=C to avoid the user’s settings to interfere with your script. For example, if you want [a-z] to match the 26 ASCII characters from a to z, you have to set LC_ALL=C.

Hope this helps! :)
