Conan version: 2.0.13

I have a conan recipe where I define the set_version() method to set my package version based on an external script.

When I try to generate the package by doing

conan create .

I get the next error:

ERROR: conanfile didn't specify version

It seems that I must use --version flag for it to work and that set_version() is not called.

  1. --version is an optional parameter of conan
  2. set_version() method is defined in conanfile
  3. For what I know, set_version() will be automatically called when doing conan create or conan export

What am I missing?

(EDIT)

    def set_version(self):
        if self.version:
            return
        version_script = self.recipe_folder / "scripts" / "version"
        self.version = check_output([version_script], text=True).strip()

  • Please, show your recipe that you are using. The set_version works even when there is no self.version defined in the recipe, it's a tested case. Probably you are having an issue to get the version from your script. Plus, you should set self.version in set_version Commented Nov 3, 2023 at 18:51
  • self.version property is not manually set in the recipe; only in set_version() Commented Nov 3, 2023 at 18:58
  • It is possible that the result of check_output is empty? please print the value and execute, to double check it is getting a value. If it is getting a value and still complaining, I'd file a ticket in github.com/conan-io/conan/issues Commented Nov 3, 2023 at 23:33
