port needs to check if python module has been installed/upgraded with pip

[gaming-hacker (G Alexander)]

Hello,

I update my python modules through pip with commands like

pip-2.7 install alabaster --user --upgrade

which results in

Collecting alabaster
  Downloading https://files.pythonhosted.org/packages/2e/c3/9b7dcd8548cf2c00531763ba154e524af575e8f36701bacfe5bcadc67440/alabaster-0.7.10-py2.py3-none-any.whl
Installing collected packages: alabaster
Successfully installed alabaster-0.7.10

checking for outdated ports returns

The following installed ports are outdated:
py27-alabaster                 0.7.6_0 < 0.7.10_0

which is obviously not the case since, it is now updated.

No, using sudo pip to install/upgrade python modules in site-packages is incompatible with MacPorts. You must not install files into ${prefix} that are not managed by MacPorts.

If you need python modules from pip, use a virtualenv.

I don't use sudo pip, these modules are installed locally with '--user'

It sounds like an interesting idea, but the opportunities for complications and errors are high. Nevertheless, if you put something together that works, no doubt we would be delighted to take a look at it and see if it can be intertwined into MacPorts!

Okay, so if you used pip --user, you installed the python modules into your home. Python modules in your home are not usable system-wide. Therefore this would not be a general replacement for the python module installed by the corresponding port.
