Describe the issue briefly here, including:

pip install rpyc == 4.0.0 fails when building wheel on windows 7 python 2.7

I setup a fresh virtualenv to reproduce the problem

MINGW64 /c
$ virtualenv test_rpyc

MINGW64 /c

Environment

• rpyc version 4.0.0
• python version 2.7.13
• operating system Windows 7

👍 I'm also seeing this issue with python 3.6 on RS4 x64, win8.1 x64 and CentOs.
This looks to be the issue

ValueError: path '/home/thomas/dev/project/rpyc/bin/rpyc_classic.py' cannot be absolute

[coldfix]

Thanks for the feedback. I assume this happens due to passing absolute paths to the scripts parameter in setup.py. Curiously, this hasn't been any different in ages, so I'm not sure why this happens only now (possibly because it wasn't an issue with wheels). I'll do a post-release shortly, please report back if you still experience problems.

[coldfix]

Follow up: curiously the installation error was not reproducible on archlinux (even if the absolute path does not exist).

The problem was probably caused by rpyc.egg_info/SOURCES.txt containing the scripts as absolute paths. The solution was to remove and regenerate this file (even without any code changes). The patch (0a7cc3c) was not needed to get the correct behaviour after all (but it might prevent similar issues in the future). Furthermore, I just learned that python setup.py sdist apparently does not force regenerating SOURCES.txt (I redid the source distribution after applying the patch with no effect).
