nikola plugin install dependency with pip in wrong python version

[davidak]

i use Nikola with python3, so it has to use pip3 to install dependencys

example: nikola plugin -i import_page

[ralsina]

So, for python 2 it's guaranteed to be available as pip2 and for python 3 as pip3, right?

[davidak]

no, it's not that simple

[ralsina]

how isn't it that simple? Anyone has a python 2 without a pip2 and a python3 without a pip3?

[ralsina]

Alternatively, it's possible to use pip as a module but I don't have details.

[da2x]

Some distros use pip3.4 with no pip3 alias. Using the module would probably be a better solution.

[ralsina]

Doesn't look very hard. For example, this works:

import pip
pip.main(['freeze'])

[ralsina]

Blah, pip is really weird. Working through it but it sucks.

Fun: pip has an internal "requests" module, so if we have requests imported that explodes awesomely.
This is not worth it. If it fails to call pip correctly, Nikola tells you "install this using your package manager or pip" and that's going to work...

[ralsina]

Yep, totally not doing this. Sorry.

[davidak]

If it fails to call pip

it just calls pip and installs it in the wrong version. can we prevent that?

[ralsina]

We can make it stop trying to install things at all.

it could just display the command.

[ralsina]

And then this bug would be "it's printing the wrong command, I ran it and
it installed things in the wrong python"

We could use sys.executable for this.
