What I've Tried:

A github repo imports bpy, so I tried

  1. to build Blender via git clone but the install_deps.sh command fail because it cannot install a requested package, libpystring-dev.

  2. pip install bpy - nope.

  3. This guy's writeup started to get somewhere, but still no recognized bpy module after an ostensibly successful run-through.

Since I need to install Blender in my WSL Ubuntu, I'm not sure else how to do this.

Corresponding Errors:

1. Build Blender via git clone:

 ./blender/build_files/build_environment/install_deps.sh
WARNING! ****WARNING****
If you are experiencing issues building Blender, _*TRY A FRESH, CLEAN BUILD FIRST*_!
The same goes for install_deps itself, if you encounter issues, please first erase everything in /home/domattioli/src/blender-deps and /opt/lib
(provided obviously you did not add anything yourself in those dirs!), and run install_deps.sh again!
Often, changes in the libs built by this script, or in your distro package, cannot be handled simply, so...

You may also try to use the '--build-foo' options to bypass your distribution's packages
for some troublesome/buggy libraries...


Ran with:
    install_deps.sh


Installing dependencies for DEB-based distribution


Source code of dependencies needed to be compiled will be downloaded and extracted into '/home/domattioli/src/blender-deps'.
Built libs of dependencies needed to be compiled will be installed into '/opt/lib'.
Please edit $SRC and/or $INST variables at the beginning of this script,
or use --source/--install options, if you want to use other paths!


Number of threads for building: 24 (automatically detected, use --threads=<nbr> to override it).
Full install: false (use --with-all option to enable it).
Building OpenCOLLADA: false (use --with-opencollada option to enable it).
Building Embree: false (use --with-embree option to enable it).
Building OpenImageDenoise: false (use --with-oidn option to enable it).


Example:
Full install without OpenCOLLADA: --with-all --skip-opencollada

  • Looks like libpystring-dev is in Jammy (22.04), https://ubuntu.pkgs.org/22.04/ubuntu-universe-arm64/libpystring-dev_1.1.3-2_arm64.deb.html. You can try installing the deb from Jammy without updating your release, YMMV. At your own risk! – pbhj Aug 30 '22 at 23:06

    Is there are way to force the installation? The deb doesn't show up with apt-file search, I suspect, because it is not available for 20.04 – domattioli Aug 31 '22 at 20:06
  • You can download it from https://packages.ubuntu.com or the other site I mentioned, install from the command line with sudo apt install ./path/to/$package (or dpkg -i). – pbhj Sep 01 '22 at 17:02
