Having issues loading libpython3.6m.a on OSX High Sierra

[cgeorgelee]

OS X 10.13.6 (17G65)
Python 3.6.4 installed in a pyenv

Having issues loading libpython3.6m.a trying to connect it to an either the system Apache or a Homebrew Apache running on port 80.

I have tried both the default system Apache and also tried using homebrew Apache. But neither work. It seems unable to load the libpython3.6m.a file into Apache.

$ pip install mod_wsgi

$ mod_wsgi-express module-config
LoadFile "/Users/myuser/.pyenv/versions/3.6.4/lib/libpython3.6m.a"
LoadModule wsgi_module "/Users/myuser/.pyenv/versions/3.6.4/envs/myprojectenv/lib/python3.6/site-packages/mod_wsgi/server/mod_wsgi-py36.cpython-36m-darwin.so"
WSGIPythonHome "/Users/myuser/.pyenv/versions/3.6.4/envs/myprojectenv"

... update the apache config ...

$ apachectl configtest
httpd: Syntax error on line 537 of /usr/local/etc/httpd/httpd.conf: Syntax error on line 1 of /usr/local/etc/httpd/conf.d/wsgi.conf: Cannot load /Users/myuser/.pyenv/versions/3.6.4/lib/libpython3.6m.a into server: dlopen(/Users/myuser/.pyenv/versions/3.6.4/lib/libpython3.6m.a, 10): no suitable image found.

You must generate a shared library. See:

• Example of enabling build with shared Python library. pyenv/pyenv#392

Updated comment for someone else (probably future me) looking for answers... So for OSX / pyenv, if the output from the module-config looks like a "libpython3.6m.a" (*.a file) then it is a Python configuration issue and you will need to reinstall Python with shared library support. Do the following:

1. Reinstall the virtual env

env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.6.6
pyenv uninstall projectenv
pyenv virtualenv 3.6.6 projectenv

2. Reinstall the pip packages into the virtualenv

pip install mod_wsgi
...

3. Rerun the module config and notice that produces a different extension (dylib). If you see

$ mod_wsgi-express module-config
LoadFile "/Users/myuser/.pyenv/versions/3.6.6/lib/libpython3.6m.dylib"
...

4. Stuff that back into httpd.conf

Thanks a ton!
