Couldn't git clone due to legacy-install-failure #51

Closed jink1994 closed 1 year ago

jink1994 commented 1 year ago

Error looks like below:

clang: warning: argument unused during compilation: '-L/usr/local/lib' [-Wunused-command-line-argument] pygraphviz/graphviz_wrap.c:2711:10: fatal error: 'graphviz/cgraph.h' file not found

include "graphviz/cgraph.h"

           ^~~~~~~~~~~~~~~~~~~
  1 error generated.
  error: command '/usr/bin/clang' failed with exit code 1
  [end of output]

note: This error originates from a subprocess, and is likely not a problem with pip. error: legacy-install-failure

× Encountered error while trying to install package. ╰─> pygraphviz

I used brew to install the graphviz in requirements. It seems like the package is installed automatically somewhere else.

Whenever you see legacy-install-failure, always adding the following line in front of pip solves the problem:

env "CFLAGS=-I/opt/homebrew/include -L/opt/homebrew/lib" pip install git+https://github.com/IBM/LNN.git

pygraphviz has been removed as a dependency
