1 month ago HI @psikorski, thank you for reporting this.
Indeed it would have been caused by https://github.com/conan-io/conan-center-index/pull/24768 - although before then, it did not work either - I did test this (quite extensively) on both Windows and Linux.
Could you run the following command in a terminal:
"C:\Python279\python2.EXE" -c "import platform;print(platform.python_version())"to check what string is being returned?
Description
Method "validate_build" (https://github.com/conan-io/conan-center-index/blob/master/recipes/qt/5.x.x/conanfile.py#L144) checks if the proper python2 version is installed if qtwebengine is set to true. And, I think, this method incorrectly checks the version based on the whole output of the
cmd_v = f"\"{python_exe}\" -c \"import platform;print(platform.python_version())\""command. As it is visible in the attached part of the log, it has a problem with parsing the version out of the command output.I think it is related to this PR: https://github.com/conan-io/conan-center-index/pull/24768
