Sphinx error: Unknown directive type "automodule" or "autoclass"

Solution 1:

The same thing happened to me! To fix it, go to the line in conf.py that says something like this:

extensions = ['sphinx.ext.todo', 'sphinx.ext.viewcode']

Yours will probably look different. Anyway, add 'sphinx.ext.autodoc' to the list. e.g.

extensions = ['sphinx.ext.todo', 'sphinx.ext.viewcode', 'sphinx.ext.autodoc']

If it was:

extensions = []

then you'd change it to:

extensions = ['sphinx.ext.autodoc']
