I don't know much about SSL and related networking things especially on Windows. I would be surprised if pip on old Python can't install from current PyPI though. I imagine that something strange has happened like a new version of pip running on an old version of Python or old Python on new OS (or old PyCharm...). There is no problem using Python 2.7 with pip and PyPI on this Linux machine but I guess it has a newer SSL library provided by the OS: $ pip install numpy DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality. Collecting numpy Downloading numpy-1.16.6-cp27-cp27mu-manylinux1_x86_64.whl (17.0 MB) |████████████████████████████████| 17.0 MB 14.3 MB/s Installing collected packages: numpy Successfully installed numpy-1.16.6 If it is actually the case that pip on Python 2.7 (on Windows) cannot download from PyPI then an easier option rather than creating a local server would just be to download the numpy wheels from PyPI using a browser: https://pypi.org/project/numpy/1.15.4/#files Then you can do pip install .\numpy-1.15.4-cp27-none-win_amd64.whl Using a newer version of Python is still my primary suggestion though. -- Oscar -- https://mail.python.org/mailman/listinfo/python-list
