Installing packages fails if Python 3 installed into path with non-ASCII characters #4984
Description
- Pip version: 9.0.1 (installed with Python 3.6.4)
- Python version: 3.6.4
- Operating system: Windows 7 and 10
Description:
Organizing training where using Python 3 for the first time. Two participants for failed to use pip for anything due to UnicodeDecodeError. After a little debugging it turned out this was due to to them having non-ASCII characters in their user name (not uncommon here in Finland) and Python 3.6 being installed under their account into a path like C:\Users\Käyttäjä\AppData\.... This was the default location offered by the Python installer.
Both users were using Windows 10, but I was able to reproduce this with my Window 7 virtual machine as well. Account with non-ASCII characters isn't needed, it's enough to install Python into any path with non-ASCII characters. A workaround was uninstalling Python and installing it directly under C:\.
What I've run:
C:\Users\peke>py -m pip --version
pip 9.0.1 from C:\Python36\lib\site-packages (python 3.6)
C:\Users\peke>py -m pip install robotframework
Collecting robotframework
Using cached robotframework-3.0.2.tar.gz
Installing collected packages: robotframework
Running setup.py install for robotframework ... error
