[networkx-2.5.1] If you want to try to fix the problem yourself, *don't* just cd to
[networkx-2.5.1] /opt/sagemath/sage-9.4/local/var/tmp/sage/build/networkx-2.5.1 and type 'make check' or whatever is appropriate.
[networkx-2.5.1] Instead, the following commands setup all environment variables
[networkx-2.5.1] correctly and load a subshell for you to debug the error:
[networkx-2.5.1]   (cd '/opt/sagemath/sage-9.4/local/var/tmp/sage/build/networkx-2.5.1' && '/opt/sagemath/sage-9.4/sage' --buildsh)
[networkx-2.5.1] When you are done debugging, you can type "exit" to leave the subshell.
