ModuleNotFoundError installing package with setuptools_scm

Describe the bug

When I try to install cutlet I get this error:

 ERROR: Command errored out with exit status 1:

How to reproduce

This should reproduce the error:

pipx install cutlet

I’m on Linux but I don’t think platform is relevant so I’ll omit verbose output, let me know if it would actually help.

Expected behavior

cutlet should have installed without issue.

---

I maintain this package, so I’d like to make sure it works. I’m not sure if I’m doing something wrong and should change it or if this is an issue with pipx.

To clarify why I’m importing setuptools_scm, if it’s not present the package is installed as version 0.0.0, which can cause issues. Importing makes sure that the package is present rather than building a package with a bogus version. setuptools-scm is specified in setup_requires, so I’m not sure if there’s something else I should do here.

scripts are platform-specific and don’t work well on Windows, so it’s better to use console_scripts instead anyway 🙂

fyi https://github.com/iterative/shtab uses setuptools_scm without needing pyproject.toml
