How do I add a directory to mayapy's PATH?

[kathal-2]

Hey! I'm trying to use a plugin that's dependent on numpy. I'm doing so through pip, so that I can install other dependencies should any come up later.

I opened Windows Terminal and ran

pip install numpy

which successfully installed numpy, but it looks like I need to install numpy specifically for mayapy.exe.

I followed this forum post and downloaded get-pip.py from here. However, when I try running get-pip.py in mayapy.exe as administrator, I get the following error:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
NameError: name 'get' is not defined

get-pip.py is in the same directory as mayapy.exe.

I also tried dragging get-pip.py into mayapy.exe. A terminal window briefly opened, and I was able to screenshot it:

If I'm not mistaken, it looks like pip is already installed, but the directory that it's installed in isn't on mayapy.exe's PATH. How can I add it?

Update: I added mayapy.exe and the pip installation directory to my PATH using this tutorial,

...But mayapy still doesn't recognize the command.

Is there anything else I should be doing?

After studying a bit of code (C++), I've obtained a more solid understanding of what exactly PATH is.

I recently learned that pip is part of virtually every Python installation. The issue wasn't that pip wasn't installed, it was that I was attempting to run pip directly within mayapy.exe rather than my system's terminal.

Here's what I did: I added C:\Program Files\Autodesk\Maya2024\bin to my system's PATH, opened a terminal window as an administrator, and ran

mayapy -m pip install numpy

That fixed it. If anyone reading this encounters an error during that last step, try navigating to mayapy's directory with

cd C:\Program Files\Autodesk\Maya2024\bin

Your PATH probably hasn't updated yet, it takes a few minutes to kick in.

I hope this helps someone out in the future, not having numpy installed has been a huge pain when attempting to use Maya/Nuke plugins and I think I've finally figured it out.
