[Scons-users] SCons can't correctly install via pip when not in a virtualenv

[Abigail Bunyan]

Installing SCons via pip works fine in a virtualenv:

    $ docker run -it --rm debian:latest
    # apt update && apt install -yq --no-install-recommends python virtualenv
    # virtualenv venv && source venv/bin/activate
    # pip install scons
    # scons --version

But not when you install SCons via pip systemwide:

    $ docker run -it --rm debian:latest
    # apt update && apt install -yq --no-install-recommends python-pip
    # pip install --upgrade pip setuptools wheel
    # pip install scons
    # scons --version
    SCons import failed. Unable to find engine files in:

      File "/usr/local/bin/scons", line 192, in <module>

Is this a known issue?
