I would like to fix the error msg and have it say you might a compiler missing?

What is a good way for us to make it easier to understand this issue?

In project manager getattr, if we cant find the contract container, check the contents of the contracts folder for a matching file name. If found, raise a different exception saying “Missing compiler plugin installation for ‘{ext}’ source types.”

Might not work for solidity files, where the file name sometimes doesn’t match the types it contains.

Perhaps just adding a simple “make sure that you have the right compiler plugins installed” or even better: search for files in the contracts/ folder and see if there are any extensions without a compiler in this situation (and suggest they install one that can handle that file type).

[sabotagebeats]

note: project.extensions_with_missing_compilers must be fed an extension, a list of extensions, or an empty list as an argument like this: project.extensions_with_missing_compilers([])

refactored this to not require an argument in #1087
