Feature-gate error when `CARGO_REGISTRIES_CRATES_IO_PROTOCOL` is set in the environment

Problem

Flowistry is based off a toolchain from 1.67 (cargo +nightly-2022-12-07), which doesn't support sparse registries (they were stabilized in 1.68). Would it be possible to base this off a more recent toolchain instead?

error: usage of sparse registries requires `-Z sparse-registry`

As a workaround, manually running cargo +nightly-2022-12-07 install flowistry_ide --version 0.5.35 --force -Z sparse-registry gets flowistry far enough that it doesn't try to install the binary itself.

ah no, that just delays the error 😞

Flowistry could not run because your project failed to build with error:
error: failed to get `aho-corasick` as a dependency of package `redacted v0.0.0 (/Users/jyn/src/redacted)`

I will 0.5.36 soon which is on nightly-2023-04-12, is that recent enough?

[jyn514]

That should work great! 1.68 branched in January so April is more than late enough :) actually at that point I think this will be on by default so I won't need the environment variable.

I will 0.5.36 soon which is on nightly-2023-04-12, is that recent enough?

Do you know when v0.5.36 will be released ?

[willcrichton]

I just released 0.5.36, so this should be fixed now.
