ImportError: undefined symbol: PyExc_ValueError #52

I cannot seem to get this plugin to work. Below is some system information:

$ vim --version
VIM - Vi IMproved 8.1 (2018 May 18, compiled Mar 29 2019 20:08:59)
$ python3 --version
Python 3.7.3
$ uname -roms
Linux 5.0.5-arch1-1-ARCH x86_64 GNU/Linux

Vim:

:echo has('pythonx') 1

:echo has('python3) 1

:set pyxversion? pyxversion=3

It should be noted that importing pynvim through standard python3 shell works without errors. But when I try to import pynvim through vim, this error happens:

:python3 import pynvim

Traceback (most recent call last):
  File "<string>", line 1, in <module>

    import greenlet
ImportError: /usr/lib/python3.7/site-packages/greenlet.cpython-37m-x86_64-linux-gnu.so: undefined symbol: PyExc_ValueError
Press ENTER or type command to continue

What could be the cause of this issue?

I guess I should have looked a bit longer. This is a duplicate of this issue: https://github.com/roxma/vim-hug-neovim-rpc/issues/28 solved by uninstalling pip version of greenlet and installing the repository version of this package.
