[Scons-users] Problem installing scons via pip

Fri Sep 21 22:03:42 EDT 2018

Thanks, Bill, I did a mini-build based on that wiki page and got this down
to two small changes:

In SConstruct at line 744 add
*        commands.append("$PYTHON $PYTHONFLAGS $SETUP_PY bdist_wheel")*

*        whl = os.path.join(build,*
*                           'dist',*
*                           "%s-py2.py3-none-any.whl" % pkg_version)  #
There must be a better way?*
*        distutils_targets.append(whl)*

In src/setup.py at 509:
#distutils.core.setup(**arguments)
*import setuptools*
*setuptools.setup(**arguments)*

Here's that mini-build that produces the wheel, which I installed and used
to build our product code.

I get a bunch of warnings in the build.log, I think the more modern
setuptools is normalizing the names per PEP 508.

T:\Python36\lib\site-packages\setuptools\dist.py:398: UserWarning:
Normalizing '3.1.0.alpha.20180921' to '3.1.0a20180921'
  normalized_version,

Then the "Install" commands (copying build/scons/dist/* to build/dist)
fail, since the generated PyPi-compatible file names don't match those
known to SCons...

Install file: "build\scons\dist\scons-3.1.0.alpha.20180921.tar.gz" as
"build\dist\scons-3.1.0.alpha.20180921.tar.gz"
scons: *** [build\dist\scons-3.1.0.alpha.20180921.tar.gz]
build\scons\dist\scons-3.1.0.alpha.20180921.tar.gz: No such file or
directory
scons: building terminated because of errors.
