[Scons-users] --no-cache-dir

[Bassem Girgis]

I tried the following Dockerfile:









*FROM opensuse:tumbleweedRUN \zypper install -y python3 python3-devel
python3-pip && \zypper clean -aRUN \pip3 install --no-cache-dir -U
setuptools wheel pip && \pip3 install --no-cache-dir scons*

And I got this error:













*Running setup.py install for scons: started    Running setup.py install
for scons: finished with status 'error'    Complete output from command
/usr/bin/python3 -u -c "import setuptools,
tokenize;__file__='/tmp/pip-build-hrmmx99j/scons/setup.py';f=getattr(tokenize,
'open', open)(__file__);code=f.read().replace('\r\n',
'\n');f.close();exec(compile(code, __file__, 'exec'))" install --record
/tmp/pip-inb19a1a-record/install-record.txt
--single-version-externally-managed --compile:    usage: -c [global_opts]
cmd1 [cmd1_opts] [cmd2 [cmd2_opts] ...]       or: -c --help [cmd1 cmd2
...]       or: -c --help-commands       or: -c cmd --help        error:
option --single-version-externally-managed not recognized
----------------------------------------Command "/usr/bin/python3 -u -c
"import setuptools,
tokenize;__file__='/tmp/pip-build-hrmmx99j/scons/setup.py';f=getattr(tokenize,
'open', open)(__file__);code=f.read().replace('\r\n',
'\n');f.close();exec(compile(code, __file__, 'exec'))" install --record
/tmp/pip-inb19a1a-record/install-record.txt
--single-version-externally-managed --compile" failed with error code 1 in
/tmp/pip-build-hrmmx99j/scons/*


Then I changed the scons install line to "pip3 install --no-cache-dir --egg
SCons" as Daniel suggested and that one passed.

However, pip
<https://pip.pypa.io/en/stable/reference/pip_install/#cmdoption-egg> seems
to dislike --egg since it gives up pip control on the setup process. It
looks like the setup of scons does not recognize the
--single-version-externally-managed option passed down by pip when the
--no-cache-diris is used. It would be nice if scons could behave in the
expected way here since lumping packages in one command while building the
container seems to save a lot of space.
