Allow fallback from tomli to toml on newer Python #129

Closed nanonyme closed 3 years ago

nanonyme commented 3 years ago

Please allow falling to toml instead of requiring tomli on new Python 3. tomli is only installable with pep517 which creates a circular dependency that you need pep517 to build pep517.

nanonyme commented 3 years ago

Come to that, looks like pep517 needs pep517 to be built so it has circular dependency on itself as well.

I'm closing this. We clearly just need to bootstrap somehow.

I'm working on a bootstrapping page as part of flit's documentation. On my phone now, so I can't quickly link it, but it should be easy to find the PR.

@takluyver it was reasonably straightforward to do, I tried as part of https://gitlab.com/freedesktop-sdk/freedesktop-sdk/-/merge_requests/5870 and created a new tool to install wheels that can be told what the build-backend is so it doesn't need to read TOML during bootstrapping.
