Hey all, I don't know if this has been asked or reported, but apparently solc needs to be added globally for solcjs to be available via CLI :

I am not sure if anyone has experienced this issue or it has been reported but I wasn't able to find it in the questions/issues raised in this course. Please let me know if I am wrong/if this is a duplicate. Thanks

Hmm... this shouldn't be the case, but if it's working for you for now, all good

Same issue with me. It only seemed to work after I installed NPM globally - as I'm currently/prefer using NPM. But no worries since the global install fixed it.

for solc to work with npm, you have to use npx instead of npm like

  npx solcjs --help
