I used sudo pip3 install git+https://github.com/TobyPDE/chianti

from chianti.

Can you try again now?

Getting a different error now.

You might need to run it with sudo -E in order for your environment variables to be available in super user mode.

Solved it! Thanks

from chianti.

ok I got the same issue. So I did locate my OpenCV libraries and include files wth the command "pkg-config --libs --cflags opencv", which returns:

pkg-config --libs --cflags opencv

I did export the three paths under $LD_LIBRARY_PATH, but when doing "sudo -E pip install git+https://github.com/TobyPDE/chianti" I still have the same error as above, which ends by:

    ----------------------------------------
Command "/usr/bin/python -u -c "import setuptools, tokenize;__file__='/tmp/pip-Dt3JrW-build/setup.py';f=getattr(tokenize, 'open', open)(__file__);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, __file__, 'exec'))" install --record /tmp/pip-upTGyc-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-Dt3JrW-build/

Can you tell me what I am doing wrong here?
thank you
