Installing environment for https://github.com/igorshubovych/markdownlint-cli fails with AttributeError: 'bytes' object has no attribute 'tell'

[Casper321]

Hi,
I am using

- repo: https://github.com/igorshubovych/markdownlint-cli
    rev: v0.32.2
    hooks:
      - id: markdownlint

Sometimes, pre-commit fails with the following error.

[INFO] Installing environment for https://github.com/igorshubovych/markdownlint-cli.
[INFO] Once installed this environment will be reused.
[INFO] This may take a few minutes...

It looks like nodeenv-1.7.0 is used.

Related with #329, in case of network glitch, nodeenv may receive a partial tar file when downloading node from official source. When it does so, it doesn't fail immediatly but propagate the partial archive (which turns out to be bytes instead of str) later on in the code, resulting in this error.

Did you came to a mitigation meanwhile @bagerard ?

[bagerard]

not really, we're using this library through pre-commit hooks so once it is installed, it gets cached and we are good for a while but I'm still hoping #329 will get merged soon

[strongishllama]

Also getting the same error as @c3b5aw. Feels like a separate issue to the original one posted though.

[Alexander-Serov]

Same thing for us. Any hotfix available?

I'm getting the same error for:

    - repo: https://github.com/pre-commit/mirrors-prettier
      rev: v2.7.1
      hooks:
          - id: prettier

I tried the latest code from master (22d4cd9) and the failure changed from AttributeError: 'bytes' object has no attribute 'tell' to http.client.IncompleteRead: IncompleteRead(42023557 bytes read, 4089771 more expected). This is consistent with what's described in #329.

The issue indeed seems to be network related. On my home network, it happens 100% of the times. On other I tried, it doesn't happen at all. Strangely, this issue appeared out of nowhere about at about the time of this GitHub issue being created. So I don't think this is an issue with my network in particular.

I have a temporary workaround by setting the Python version in the GitHub workflow to 3.10 or lower. This may be useful to people who find this issue.

I was wrong.
