Tomo Suzuki commented on BEAM-8787:
-----------------------------------

I'm feeling our python3.6 installation is broken:


{noformat}
suztomo@suxtomo24:~$ which python3.6
/usr/bin/python3.6
suztomo@suxtomo24:~$ python3.6 --version
Python 3.6.8
suztomo@suxtomo24:~$ python3.6 -m pip install foo
Traceback (most recent call last):
  File "/usr/lib/python3.6/runpy.py", line 193, in _run_module_as_main
    "__main__", mod_spec)

>                 URL: https://issues.apache.org/jira/browse/BEAM-8787
>             Project: Beam
>          Issue Type: Bug
>          Components: build-system
>    Affects Versions: 2.16.0
>         Environment: debian x86 (gLinux)
>            Reporter: Elliotte Rusty Harold
>            Priority: Major
>
> This could be an issue with incomplete or inaccurate contributing docs. tldr; `./gradlew check` fails on Debian after initial checkout.
> The docs say that one should first run:
> sudo apt-get install \
>     openjdk-8-jdk \
>     python-setuptools \
>     python-pip \
>     virtualenv
> but even after running this pieces are missing. I'm still debugging exactly what's missing but the symptoms look like this:
> > Task :sdks:python:test-suites:tox:py35:setupVirtualenv FAILED
> The path python3.5 (from --python=python3.5) does not exist
> > Task :sdks:python:test-suites:tox:py36:setupVirtualenv FAILED
> [ant:fmpp] Traceback (most recent call last):
> [ant:fmpp]   File "/usr/lib/python3/dist-packages/virtualenv.py", line 25, in <module>
> [ant:fmpp]     import distutils.sysconfig
> [ant:fmpp] ModuleNotFoundError: No module named 'distutils.sysconfig'
> ...
> FAILURE: Build completed with 2 failures.
> 1: Task failed with an exception.
> -----------
> * What went wrong:
> Execution failed for task ':sdks:python:test-suites:tox:py35:setupVirtualenv'.
> > Process 'command 'virtualenv'' finished with non-zero exit value 3
> Indeed there is no Python 3.5 on this system:
> gnome-user-share                      python2.6
> gnome-vfs-2.0                         python2.7
> gnupg                                 python3
> gnupg2                                python3.6
> gold-ld                               python3.7
> goobuntu-config-tools                 python3.8
> But nowhere in the setup docs do we say that Python 3.5 is required to build this.
