I have the same problem (basically the same error message) trying to pip install bpy on mac python 3.9

AdamStormhardtGH commented 2 years ago

Just went through this. The pip page specifies >=3.7 and <3.8 so I'd suggest the following steps

Install python 3.7 in a new virtual environment (via miniconda / conda / anaconda or whatever)
jump to that environment (confirm you're on the right version with python --version - mine was Python 3.7.13)
pip install future_fstrings because it's going to complain about that
pip install bpy && bpy_post_install

ColtPtrHun commented 2 years ago

Same problem for me. Funny there's no 3.7 installer for windows, the only version this package works with: https://www.python.org/downloads/windows/ (@AdamStormhardtGH I assume this is why you suggested the virtual environment.)

An update on this.

I ended up abandoning a pip installation after seeing some more issue and just leveraging the bpy installed as part of the blender package.

This lets me:

Sidestep the entire process of having to install bpy via pip.
Just update blender as needed and remain up to date
Not wrestle with version incompatibility
Not mess around with having to host a blender specific Venv (as much as I'd like to, i found this pretty flaky, at least on my OSX M1 Studio)

My new commands are using subprocess to just call the python command.

import subprocess

blender_job_command = f"blender {cwd}/src/blend/template_scene.blend --python {cwd}/src/scripts/my_main_python_script.py" 
subprocess.Popen(blender_job_command, shell=True, stdout=subprocess.PIPE)

Note that this has kinda made me have to work more modularly and pull a lot of the blender interaction out into more discrete steps, but it's pretty reliable.

If you're interested in doing this

Setup (MAC) - sorry I'm not sure how this will translate to windows =/. Maybe the windows linux subsystem will be compatible but I have not tested this :

Find the location of the python version hosted in blender. For mac it's /Applications/Blender.app/Contents/Resources/3.1/python/bin/python3.10
Now install appropriate libraries for that version. There are 2 options here:

Option 1: Locally (default)

Doing pip installs will default to local, which is okay if you want to add an environment variable in the next step.

tell blender it needs to look at your .local file with:

import os
sys.path.append(f'~/.local/lib/python3.10/site-packages/') #python packages registration. This lets us use pandas etc

Option 2: System level

sudo -H pip install <package_name>
The -H tells pip not to install into the .local location. Note that I found I needed sudo in order for my terminal to respect -H
All libraries should just work now when running your script

Not an ideal fix, but it's removed some of the headaches around this bpy stuff. I haven't worked with a library which acts like this before. Hopefully it becomes a little more universally installable in the future.
