Bug report.

It appears the issue is a corporate proxy/firewall/mitm-box is not allowing traffic to pypi.org and/or files.pythonhosted.org.

Turn off firewall/AV as a test.
Try:

python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

Newest version of pip is 18.0.

C:\>pip -V
pip 18.0 from c:\python37\lib\site-packages\pip (python 3.7)

C:\>pip install numpy

hello
I uninstalled version 3.5 of python and replaced it with a new version of python (pyton 3.7). Then I desabled the kaspersky antivirus, so I managed to install the numpy and scipy libraries.
But the installation of the library matplotlib, unfortunately failed
See the attached image describing the problem


I need help to complete the installation of the matplotlib library
thank you

Don't post image as it do not show all error message(cmd Ctrl-a now Enter and all text is copied)

Get Wheel here or here
Eg you choose for your Python version.

pip install matplotlib-3.0.0-cp37-cp37m-win32.whl

[atlass218]

hello;

at the website : https://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib

I selected and choose this file: matplotlib-2.2.3-cp37-cp37m-win_amd64.whl
I install it and I belive that it's well now (pip install matplotlib-2.2.3-cp37-cp37m-win_amd64.whl)

thank you for your information and advice
