distutils is deprecated and will be removed, so we shouldn't be using it. We were using it to compute LLDB_PYTHON_RELATIVE_PATH. Discussing a similar issue [at python.org](https://bugs.python.org/issue41282), Filipe Laíns said: If you are relying on the value of distutils.sysconfig.get_python_lib() as you shown in your system, you probably don't want to. That directory (dist-packages) should be for Debian provided packages only, so moving to sysconfig.get_path() would be a good thing, as it has the correct value for user installed packages on your system. So I propose using a relative path from `sys.prefix` to `sysconfig.get_path("platlib")` instead. On Mac and windows, this results in the same paths as we had before, which are `lib/python3.9/site-packages` and `Lib\site-packages`, respectively. On ubuntu however, this will change the path from `lib/python3/dist-packages` to `lib/python3.9/site-packages`. This change seems to be correct, as Filipe said above, `dist-packages` belongs to the distribution, not us. Reviewed By: labath Differential Revision: https://reviews.llvm.org/D114106
