`bpy` cannot find the startup scripts dir

Building Blender

When building Blender as a Python module lately I have been having a weird issue where if I copy the 2.91 scripts dir into the correct place (used to be you had to copy it net to the python executable), it complains that

Has anyone else been having this issue lately? It used to work fine; I just got back into building Blender again as I saw 2.91 had an official release but am struggling to get the Python module to build for some reason.

I don’t have time to look my self but if i were to troubleshoot this, i’d probably use procmon to see in what folder it is actually looking for the scripts and see why it is looking there.

Why is it linking to an EVIL corporation website?
Are people forgetting that Blender is a Free Software project?

There is no need for such behavior, please tone it down a bit.

I think I’m a bit too noobish to use procmon.exe to full effect; could you offer any advice? There is a lot of information that I don’t need and when I put a filter on it says somewhere on the order of 5 hours to complete the filter.

My temporary solution to looking into this was to add some printouts to path_util.c's BLI_path_join function. Oddly, after a rebuild and importing once more, it seems to be looking for everything in the %LOCALAPPDATA% and %APPDATA% locations.

Not sure what changed this since trying to trace back a file path through the code is, for some reason, very complex. I’m not actually seeing any plaintext paths? Rather, Blender exchanges a bunch of enums around like BLENDER_SYSTEM_SCRIPTS which really doesn’t mean much to me. Where are these paths defined at?

Actually maybe it’s platform_win32.cmake line 732; that was modified 2 months ago on https://developer.blender.org/D9189 to say:

726   if(DEFINED ENV{BLENDER_USER_SCRIPTS})
727     message(STATUS "Including user scripts from environment 728 BLENDER_USER_SCRIPTS=$ENV{BLENDER_USER_SCRIPTS}")
728     set(USER_SCRIPTS_ROOT "$ENV{BLENDER_USER_SCRIPTS}")
729   else()
730     message(STATUS "Including user scripts from the profile folder")
731     # Include the user scripts from the profile folder in the blender_python_user_scripts project.
732     set(USER_SCRIPTS_ROOT "$ENV{appdata}/blender 734 foundation/blender/${BLENDER_VERSION}/scripts")
733   endif()

@TylerGubala hi, while I’m not on windows, it would be good to keep it working on all platforms.

I know it’s tedious, but could you confirm the exact commit that caused the problem? (using git-bisect, or manually bisecting).

It seems you know the approximate time this broke, so it shouldn’t take too long.

If we know the commit that caused the problem, it might not be so difficult to resolve the issue.

7

I did a quick lite bpy build, seems to load just fine with no issues?

edit: even regular bpy build seems just fine

do you have BLENDER_USER_SCRIPTS env var set by any chance?

8

No, that’s not set when I look at my environment variables.

I’m not sure what is causing the issue; it used to work fine in a venv…

Need some more time to look at it. Lately have been too busy to really check.

I only just got back to this but I can install bpy in my system Python.

But any attempt to use bpy only in a venv fails. You have to install the scripts 2.93 folder into the system Python first.

What’s bizarre is that once the 2.93 Scripts directory is in the system Python path, the venv Python is able to find the startup scripts.

PS C:\Users\TGubs\Code\Python\blenderpy-test> venv\Scripts\activate
(venv) PS C:\Users\TGubs\Code\Python\blenderpy-test> py
Python 3.7.9 (tags/v3.7.9:13c94747c7, Aug 17 2020, 18:58:18) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import bpy
>>>

In previous versions, I had to move the 2.93 (or whatever) folder sibling to the current Python executable, so in the venv folder for instance. That made (some) sense to me since different venv should be able to have support for different versions of bpy to be installed. Better yet if it looked in the Scripts directory.

I will need to look deeper and try to figure out what caused this.
