背景和尝试：
我在尝试着构建 Blender在 Ubuntu (20.04) WSL2 终端中。我完成了“基本设置”构建说明，但./blender/build_files/build_environment/install_deps.sh在“高级设置”自动依赖项安装说明中运行命令会出现错误：
$ ./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
Use --help to show all available options!
Do you want to continue (Y/n)?y

E: Unable to locate package libpystring-dev

我已经更新了路径信息以解决以下问题：库字体配置，如上所述这里
但以下“操作方法”安装说明为了libpystring也会产生错误：
