I am currently missing some extra packages in the Python bundled with Blender.

E.g.:

import pyproj Traceback (most recent call last): File "/snap/blender/5374/4.2/python/lib/python3.11/code.py", line 90, in runcode exec(code, self.locals) File "<blender_console>", line 1, in <module> ModuleNotFoundError: No module named 'pyproj'

whereas in a standalone Python console:

>>> import pyproj >>> pyproj.__version__ '3.6.1'

This thread is not helping much because to get a cutting-edge Blender version on Ubuntu 22.04+, it has to be installed with snap. Blender install folder is then /snap/blender/5374/4.2/ and everything in that folder is owned by root.

Also, there doesn't seem to be any pip or ensurepip executable in that folder.

Hence my question, how could I install (in the most user friendly way) a Python package which will be installed into the Python embedded with Blender (e.g. probably here: /snap/blender/5374/4.2/python/lib/python3.11/site-packages/) in that specific use case?

If that may be relevant, here are the knows paths in the Blender scripting console:

 import sys for i,j in enumerate(sys.path): print(i,j) 0 /snap/blender/5374/4.2/scripts/startup 1 /snap/blender/5374/4.2/scripts/modules 2 /snap/blender/5374/4.2/python/lib/python311.zip 3 /snap/blender/5374/4.2/python/lib/python3.11 4 /snap/blender/5374/4.2/python/lib/python3.11/lib-dynload 5 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages 6 /snap/blender/5374/4.2/python/lib/python3.11/site-packages 7 /snap/blender/5374/4.2/scripts/freestyle/modules 8 /home/<username>/.config/blender/4.2/scripts/addons/modules 9 /snap/blender/5374/4.2/scripts/addons_core 10 /home/<username>/.config/blender/4.2/scripts/addons 11 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/ifcopenshell/lib/linux/64bit/python3.11 12 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/ifcopenshell/express 13 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf 14 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf 15 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf 16 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf 17 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf 18 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf 19 /home/<username>/.config/blender/4.2/extensions/.local/lib/python3.11/site-packages/odf

(don't ask me why the last line occurs so many times...)

  • $\begingroup$ It's definitely a nightmare to install stuff within /snap/ directory... Even with the root user you face the message "Defaulting to user installation because normal site-packages is not writeable". I secretly wish that Blender's dev could upgrade the blender apt package to a higher version than 3.0.x $\endgroup$ Commented Sep 26, 2024 at 10:53

  • $\begingroup$ Hi, thanks for the suggestion! I didn't found that post. But from what I can read, it's not about the Blender snap package and there's too much hacks to be run from inside the Python shell which I really want to avoid. Meanwhile, I decided to drop the snap package because it's too rigid and I don't want to mess with mounting points at the OS level. I'm now exploring the installation from the official tarball where I'm having some kind of hope, and my first successes. $\endgroup$ Commented Sep 26, 2024 at 18:34

I've had a lot of problems with modules and dependencies... I'm writing an addon to make this easier on Linux. A little tip for this problem: (Run the following script in a text editor)

import bpy, sys, subprocess your_module = 'pyproj==3.6.1' dir_p = sys.executable install = (f' -m pip install -U {your_module}') command = (dir_p + install) result = subprocess.run(command, shell=True, check=True, capture_output=True, encoding='utf-8') print('FINISHED')

The last line > every time you reload a user script it adds a line to the path... It also has a solution.
