Unable to install setuptools-scm from source due to tomli project's pyproject.toml

[safiyat]

While installing bcrypt-4.0.1.tar.gz from source, the dependency chain includes setuptools-scm.

setuptools-scm requires tomli, whose pyproject.toml the pre-installed toml is unable to parse.

Which pip version do you use? And how come you are using toml 0.10.0, when the newest version is 0.10.2?

reopening this as the version got yanked due to a regression
