This seems to be an issue with the "contrib" module pyopenssl that is provided as a courtesy with urllib3. The latter is 100% python 3 compatible from what I read in their docs. Looking at that contrib module however: https://github.com/shazow/urllib3/blob/master/urllib3/contrib/pyopenssl.py In the first few lines in the module docstring it states it is for Python 2. I guess you won't be able to use this urllib3 contrib module with python 3. Maybe you can contact its author to ask for a fix? Irmen -- https://mail.python.org/mailman/listinfo/python-list

You have something that needs to build a C extension. To do that,
you need to have the Python headers installed. How did you install
Python? On Debian/Ubuntu family Linuxes, that's probably "apt-get
install python3" - so getting the headers would be "apt-get install
python3-dev". Give that a try, and then retry the pip install.
I should have thought about that myself. :-(

You have something that needs to build a C extension. To do that, you

On Debian/Ubuntu family Linuxes, that's probably "apt-get install

That gets installed. And then I get:
ImportError: No module named 'cryptography'
So I try to install that. This gives:
Command /usr/bin/python3 -c "import setuptools,
