Pip reference broken


#1

It seems there is something broken on the multipass install.
I’m trying out a super plain publish of a python based snap.
It fails trying to run pip.

Run the same command again with --debug to shell into the environment if you wish to introspect this failure.
An error occurred when trying to execute ‘sudo -i env SNAPCRAFT_HAS_TTY=True snapcraft snap’ with ‘multipass’: returned exit code 2.


#2

I think it is a bug in the python plugin, try clean the python plugin part and rebuild again.


#3

I’ve done ‘snapcraft clean’ 10+ times, is there another way to do that?


#4

Can you share your snapcraft.yaml? It’s very hard to debug without seeing what you’re asking snapcraft to do


#5

I’m happy to write the snapcraft.yaml any way needed, if I can just get a basic Python script to run. I tried to write one based on examples that seemed to be supposed to work.
