Cargo dependency for anchor.py

During a docker container build with anchor.py==0.8.0 in requirements.txt we are encountering the following error -

Is there a known fix for this?

We have tried adding a rust dependency manually in a Docker build to work around it with little luck - things get stuck indefinitely in the following stage:

Collecting pyheck<0.2.0,>=0.1.4
  Using cached pyheck-0.1.5.tar.gz (3.4 kB)
  Installing build dependencies ... -

Any recommendations would be greatly appreciated!

python3 -m pip install --upgrade pip

I think this is actually the only part you need.

What you’re seeing is pip trying to build pyheck from source, which it shouldn’t be doing in this case.

Pyheck has prebuilt wheels on pypi for all the common platforms so you don’t need to have rust installed.

However I remember some older versions of pip not being able to find these wheels. So yeah just use an up-to-date pip

@raymondjacobson did you figure out if something was wrong in the end? I’m going to be inflicting some Rust on solana-py and would like to know if there’s something missing for some platform
