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:
export LC_ALL=C
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! :)
