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:
