@seleem1337 Thanks for addressing this issue. Its a blocking my workplace from requiring use of poetry in a large corporate environment.

I just tried out this fix and it didn't seem to work. I got this error:
{path to my package} does not contain any element

I made the following change and then it worked as expected:

        return_code = installer.run()

        if return_code != 0:
            return return_code

        if self.option("no-root"):
            return 0

        try:
            builder = SdistBuilder(self.poetry, NullEnv(), NullIO())
        except ModuleOrPackageNotFound:
            # This is likely due to the fact that the project is an application
            # not following the structure expected by Poetry
            # If this is a true error it will be picked up later by build anyway.
            return 0

        self.line(
            "  - Installing <info>{}</info> (<comment>{}</comment>)".format(
                self.poetry.package.pretty_name, self.poetry.package.pretty_version
            )
        )

        if self.option("dry-run"):
            return 0
