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

[Abigail Bunyan]

    # python --version
    Python 2.7.13
    # pip show scons | grep 'Location:'
    Location: /usr/local/lib/python2.7/dist-packages
    # ls -F /usr/local/lib/python2.7/dist-packages | grep -i scons
    scons-3.0.1/
    scons-3.0.1.dist-info/
    # ls -F /usr/local/lib/python2.7/dist-packages/scons-3.0.1
    SCons/

So it looks like the issue is that SCons is (for whatever reason) looking under:
    /usr/local/lib/python2.7/dist-packages/lib/scons-3.0.1
but installed in:
    /usr/local/lib/python2.7/dist-packages/scons-3.0.1

Which version of python is this running under?

There are some known issues with non virtualenv pip install, I'm not sure this is one of them.
Can you find where the SCons engine files are actually installed on you system?

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:
      /usr/local/bin/../engine

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

    ImportError: No module named SCons.Script

Is this a known issue?
