On the same server, I successfully ran pip install virtualenv with python 2.7.x.  

Now, I've just installed python3.4 using curl https://bootstrap.pypa.io/get-pip.py | python3.4.  

➜  ~ pip --version
pip 8.1.1 from /usr/lib/python3.4/site-packages (python 3.4)

pip uninstall virtualenv throws the same error too

The root cause is: your environment variable LC_ALL is missing or invalid somehow Short answer- just run the following command: $ export LC_ALL=C If you keep getting the error in new terminal windows, add it at the bottom of your .bashrc file. Long answer- Here is my locale settings: $ locale LANG=en_US.UTF-8 LANGUAGE= LC_CTYPE="C" LC_NUMERIC="C" LC_TIME="C" LC_COLLATE="C" LC_MONETARY="C" LC_MESSAGES="C" LC_PAPER="C" LC_NAME="C" LC_ADDRESS="C" LC_TELEPHONE="C" LC_MEASUREMENT="C" LC_IDENTIFICATION="C" LC_ALL=C Python2.7 $ uname -a Linux debian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt11-1+deb8u6 (2015-11-09) x86_64 GNU/Linux $ python --version Python 2.7.9 $ pip --version pip 8.1.1 from /usr/local/lib/python2.7/dist-packages (python 2.7) $ unset LC_ALL $ pip install virtualenv Traceback (most recent call last): File "/usr/local/bin/pip", line 11, in <module> sys.exit(main()) File "/usr/local/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 579, in setlocale return _setlocale(category, locale) locale.Error: unsupported locale setting $ export LC_ALL=C $ pip install virtualenv Requirement already satisfied (use --upgrade to upgrade): virtualenv in /usr/local/lib/python2.7/dist-packages
