      Description

      I tried to rebuild mongodb according to building.md(github repo) and I got the following error when executing the scons scrtip(sudo python3 buildscripts/scons.py install-mongod):

       Generating build/opt/mongo/db/repl/rollback_gen.cpp
      /usr/bin/python3 src/mongo/base/generate_error_codes.py src/mongo/base/error_codes.yml src/mongo/base/error_codes.tpl.h build/opt/mongo/base/error_codes.h

      scons: building terminated because of errors.

      Note:

      I have Cheetah installed in /home/ubuntu/.local/lib/python3.8/site-packages/Cheetah and it is in PYTHONPATH. The potential problem might be that the subprocess has no idea of the original ENV variable but I don't know how to fix it. Specifically, I don't know which file invoked this subprocess.
