I'm having issues getting cefpython to install on Mac. I know someone who got it to install fine on windows, but on Mac, no dice. I've tried pip3 install cefpython3==66.0, but it throws this error:
Defaulting to user installation because normal site-packages is not writeable
ERROR: Could not find a version that satisfies the requirement cefpython3==66.0 (from versions: none)
ERROR: No matching distribution found for cefpython3==66.0
I should also note that I haven't had issues installing other packages with pip3. I thought that I might need to use pip instead of pip3, but that currently isn't working either.
cefpython366.0 provides wheels for Linux, w32/w64 and MacOS, but only for Intel processors. Other releases provide even less. And there is no source code.To install cefpython3 on MacOS M1 you need to compile from sources. See https://github.com/cztomczak/cefpython/blob/master/docs/Build-instructions.md
