[error] Error when calling conanfile.info.clone()

See original GitHub issue

I am trying to achieve VS downward compatibility by using the new feature in package info. I have the following method:

def enable_visual_studio_downward_compatibility(conanfile):
    if conanfile.settings.compiler == "Visual Studio" and conanfile.settings.compiler.version == "16":
        for version in ("15", "14"):
            compatible_pkg = conanfile.info.clone()
            compatible_pkg.settings.compiler.version = version
            conanfile.compatible_packages.append(compatible_pkg)
    if conanfile.settings.compiler == "Visual Studio" and conanfile.settings.compiler.version == "15":
        for version in ("14"):
            compatible_pkg = conanfile.info.clone()
            compatible_pkg.settings.compiler.version = version
            conanfile.compatible_packages.append(compatible_pkg)

And the package uses:

 def package_id(self):
   enable_visual_studio_downward_compatibility(self)

From my understanding and reading the documentation, this is the right way to enable compatibility. However, when a VS2019 consumer tries to consume a VS2015 package, I get the following error:

ERROR: package/version@user/stable: Error in package_id() method, line 53
        enable_visual_studio_downward_compatibility(self)
while calling 'enable_visual_studio_downward_compatibility', line 8
        compatible_pkg = conanfile.info.clone()
        ConanException: 'minor_mode' is not a known package_id_mode

Is this a bug or am I doing something wrong here? (I am using Conan 1.22.2)

Yeah you are right, there was something wrong with the dependencies. I reinstalled the dev branch and that works fine now. Sorry about that.

Much better, it will go for 1.22.3 😉
