Import error in latest version of web3.py pip package

[ehtec]

• Version: 6.6.0
• Python: 3.9
• OS: Debian 11

The latest version 6.6.0 that was released about an hour ago of the web3 pip package is broken, it cannot be imported without raising an error. I noticed this because it broke our CI pipelines.

Python 3.9.2 (default, Feb 28 2021, 17:03:44) 
[GCC 10.2.1 20210110] on linux
Type "help", "copyright", "credits" or "license" for more information.

I have the same issue!

I am not able to replicate. I wonder if there is a caching issue in your CI? Can you clear your cache in CI and let me know?

I don't believe this is a caching issue, as other people have the same issue as well, it happened right after the release of the latest verison of web3py, I could replicate it on my laptop (the screenshot above is actually from my laptop, where I upgraded web3py to test), and the locate command is telling the that the normalization_spec.json file indeed does not exist on my system.

@ehtec How are you installing?

@ehtec How are you installing?

python3 -m pip install --upgrade web3

I believe that these .json files, which seem to be new according to the commit history, are not included in the pip package by default and need to be manually specified in the setup.py configuration which is currently not the case, as far as I have seen.

Yeah, I don't see it in the tar file. Thanks for raising and troubleshooting. Will put a patch up shortly.

@ehtec @Rogalek Patch release v6.6.1 is out now with that change in there... please let us know if that solves your issue. Thanks again for reporting!

Hi. i have the same issue using pyinstaller.
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/_MEICqEE2v/ens/specs/normalization_spec.json'
using 6.6.0, 6.6.1 and the latest version too 6.8.0

@B2f4 pyinstaller needs a manual addition utilizing the --add-data flag.
