I installed libffi-dev and libssl-dev Raspbian packages, and run "tox -e narrativedocs" again. Now the error was about missing "sphinx-build" executable. So I activated virtualenv where Sphinx was previously installed and again issued "tox -e narrativedocs". Now the output was:

ERROR: narrativedocs: commands failed
(twisted-dev-env) pi@zyuzino11:~/ColourDreams/Twisted-dev $
The error is "twisted" module missing. How could I fix that? Should I install Twisted Python package to my virtualenv? Now I only have Twisted Python package installed globally.

- sudo pip install tox (Glyph said I shouldn't install packages globally but it's too late for this Raspbian installation...)
- Changed current directory to that where tox.ini resides
- I didn't activate any virtual environments
- tox -e narrativedocs
The result was fail, if I understood correctly, due to this error:Running setup.py bdist_wheel for cryptography: startedRunning setup.py bdist_wheel for cryptography: finished with status 'error'Complete output from command /home/pi/ColourDreams/Twisted-dev/build/narrativedocs/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-build-LEVwwA/cryptography/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" bdist_wheel -d /tmp/tmpTiRC7Rpip-wheel- --python-tag cp27:Package libffi was not found in the pkg-config search path.Perhaps you should add the directory containing `libffi.pc'to the PKG_CONFIG_PATH environment variableNo package 'libffi' foundMaybe it's because Raspbian is not suitable for twisted development? If this is the case, can I use Windows?Raspbian should be fine, but you do have to have enough dependencies installed. In this case you need to apt install libffi-dev and openssl-dev; it will be slow to build the first time (for each version of python) but it will speed up a lot after that due to build caching.(Specifically this is because it is building Cryptography, which does not yet ship a manylinux1 wheel.)Let me know if that works,-g
