[BUG] Check command exited with non-zero return code: 126.

[michealroberts]

Check command exited with non-zero return code: 126.

Bug description

When running pyre check which has been installed via poetry, with poetry run pyre check I am getting the following error code:

Check command exited with non-zero return code: 126.

Without any other debug information.

Reproduction steps

Simply pyre init inside a project, with watchman installed with the following configuration:

poetry run pyre init

.pyre-configuraiton:

{
  "debug": true,
  "site_package_search_strategy": "pep561",
  "source_directories": [
    "./packages*",
    "./apps*"
  ]
}

poetry run pyre --noninteractive check

Expected behavior

It should run against the code, and exit safely.

2024-03-12 16:26:04,352 [PID 13083] ERROR Check command exited with non-zero return code: 126.

pyre rage > pyre_rage.log, Output:

pyre_rage.log

Additional context

All I can say is I have a minimal python project inside a container, setup with poetry, and pyre and pysa do not work. Both exit with code 126 with no other output.

Is there a verbose mode where I can check further logs?

[ebrahimsofi123]

Hi Michael, Thank you for bringing up this issue. Looking at the problem that you stated which said that "Check command exited with non-zero return code: 126," generally indicates an issue with permissions or an inability to execute a binary. When I look at the issue that you are facing, i see some steps that can be taken to rectify the problem namely:

1. Check the executable permissions : As you are using a pyre in a container, there can be instances where the permissions can get mixed up. set the executable permission on the Pyre binary using "chmod +x /usr/src/app/.venv/bin/pyre.bin'

2. Based on the logs you provided, Pyre seems to ignore the "debug" flag set in the configuration file. You can enforce verbose output directly via the command line to get a little bit more details on the log. Try to modify the pyre command in the following way "poetry run pyre --noninteractive --debug check"

3. Try simplifying your .pyre-configuration temporarily to see if a particular configuration is causing the issue. Something like { "source_directories": ["."] }

4. Try running pyre outside of poetry to isolate the issue. source /usr/src/app/.venv/bin/activate pyre check

I beilieve that going through these debugging steps, you might be able to figure out the reason why you are facing the error in line 126. I hope this helps :)
