cc @Electroid, I don't know what the policy about support Rust versions is for wrangler.

My fault, must be time to upgrade 😏

[mattlockyer]

Confirmed, installed successfully. Sorry forgot to include my version number in the OP.

There really needs to be an error prompt saying you need a new version of Rust before it builds 400 packages.

[jyn514]

Cargo is about to stabilize rust-version in Cargo.toml for 1.56: rust-lang/cargo#9732
But it won't help for any toolchains earlier than that; cargo doesn't give us a way to run code before dependencies are built.

That's good to hear. Better than never doing it, but in the short term I guess others will have to make the same mistake as I.
