conan-center hook always reports "pre_export(): could not get source code" on WIndows

[tt4g]

I tried to build after enabling conan-center hook on Windows 10 but I get error message "ERROR: [HOOK - conan-center.py] pre_export(): could not get source code".
This recipe can build on docker container conanio/gcc7.

Is conan-center hook not supported Windows 10?

[tt4g]

I'm using conan installed by Windows installer, that is bad?

Hi @tt4g which Conan client version are you running? Where did you install conan hook files (system path e.g. C:/Users/foobar/.conan)?

[tt4g]

I'm using 1.22.2:

$ conan --version
Conan version 1.22.2

Hooks installed here: C:\Users\tt\.conan\hooks, and list:

I challenged by disabling the Windows application alias. However, I got the same message as the issue.

Yes, the Windows installers bundles a python interpreter in it, so it might be an issue. If you could try to run in Windows with the pip-installed Conan, that would help to isolate the issue.

[tt4g]

@memsharded Right. conan installed by pip is works for me.

I was uninstalling python because Windows application alias often do bad when calling python3. That was bad.

[memsharded]

Thanks @tt4g for following up!

[uilianries]

@memsharded should we investigate Windows installer?

[memsharded]

@uilianries yes, better. Please do a quick check if the hooks work for the Windows installer. Thanks!

[steinerthomas]

The hooks still doesn't work for the Windows installer. I also had to install conan via pip.
@uilianries any updates?

[claremacrae]

The same error occurs when running conan installed via choco.

I got this problem using the Debian installer on Debian Sid

I think this problem deserves further investigation, but one issue per package manager/platform. I'll check for Debian first

TLDR: Attribute checker could be the problem

Here's my two cents: I have conan installed with the windows installer. I had upgraded versions, and as someone who has been contributing to the conan-center once in a while, I had some hooks. I had been getting the "could not get source code" error. I eventually looked into my hook config to take them out. I noticed I had the attribute-checker and the conan-center hooks. Out of curiosity, I removed only the attribute checker, and now it works...

I don't know whether this is a problem with the attribute checker, or it's because of trying to use multiple hooks, or that it is only between attribute checker and conan center hooks that a conflict emerges.

[chausner]

I am running into this issue on Windows. I installed Conan via winget.

I also face the issue both on Windows 7 x64 and LUbuntu 21.04 64-bit. I installed conan from the Downloads page on both the systems.
