ModuleNotFoundError: No module named 'eth_hash' when trying to import this with poetry

[flokli]

What was wrong?

I added eth_utils (trough eth_abi) to a python project, which uses poetry to manage dependencies.

It seems poetry doesn't pick up eth_hash as a dependency of eth_utils:

Code that produced the error

poetry init
poetry add eth_abi
# create code with `from eth_abi import encode_abi`
poetry install
# run your code

Output:

Expected Result

I assume eth-utils would need to list its dependencies in pyproject.toml.

Install eth-hash 0.3.2 using

pip install eth-hash

It might solve the problem

[flokli]

Yes, manually adding it to my project works. However, if eth-utils depends on eth-hash, it should declare this in its dependencies, no?

[carver]

eth-utils does specify eth-hash as a dependency. Have you tried using a fresh virtualenv with pip install eth-utils?

Closing as not a bug unless there's a problem with basic pip (will consider it a poetry bug).
