Can't install python package with c

[magician333]

if i use pip install python package which include C (such as lxml , misaka ) , it will wrong. By the way ,I installed gcc and python-dev

[fornwall]

For lxml you add libxml2-dev and libxslt-dev, so the full list of dependencies to install should be:

apt install clang libxml2-dev libxslt-dev python-dev

After that you should be able to pip install lxml - show me the error message if this does not work for you!

[fornwall]

Install the dependency (for cffi, which misaka depends on):

apt install libffi-dev

and finally install misaka with:

pip install --upgrade --force-reinstall misaka

where --upgrade --force-reinstall forces rebuilds of packages that you may have builkt with older gcc versions. Let me know if this works for you!

@magician333 Ok, can you double-check that you have the right gcc version by running apt-cache show gcc | grep Version and verify that the output is Version: 5.3.0-2?

Can you also try to reinstall cffi:

pip uninstall cffi
pip install cffi

and then try to install misaka again?
