Hi @MarcelRaad @NoWiseMan

Quick question: What is the purpose of running a conan inspect over a conanfile.txt? I guess it is a typo and it meant conanfile.py?

Also a quick note: Since Conan 2.0 has been in alpha, the Conan v2 mode has been no longer maintained, so the set of validations and checks that it implements would be small compared to everything that Conan 2.0 alphas and betas have been providing. It is recommended to start running things against the released betas to check what could be failing, and report possible issues.

and want to enable CONAN_V2_MODE globally to catch issues already while developing.

Yes, that is the thing, I don’t think that CONAN_V2_MODE will capture more than 20% of the 2.0 changes, so at some point installing 2.0 (in a python virtualenv, recommended) will be the only way.

But the workaround will do for that.

If the workaround is enough atm, then I will close this issue as “not planned”, but feel free to re-open if necessary. Thanks!
