use of undeclared crate or module `tracing` #4939

Closed mutantbob closed 2 years ago

mutantbob commented 2 years ago

Version

tokio v1.17.0 tokio-util v0.7.1

Platform

Linux herakleion 5.4.72-gentoo #1 SMP Fri Nov 13 19:51:13 EST 2020 x86_64 Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz GenuineIntel GNU/Linux

Description I dusted off an old app that uses the reqwest crate and tried to compile it and got the following error:

error[E0432]: unresolved import `tracing`
  --> /home/thoth/.cargo/registry/src/github.com-1ecc6299db9ec823/tokio-util-0.7.1/src/codec/framed_impl.rs:15:5

The problem evaporated after a cargo update, but there may be other old apps with a Cargo.lock that triggers this problem.

Darksonn commented 2 years ago

We can't do anything about problems in old releases, so there's nothing to do here. This isn't an issue in the newest release.

matthiasg commented 6 months ago

@Darksonn i have this just now..

error[E0433]: failed to resolve: use of undeclared crate or module tracing --> /Users/mgt/.cargo/registry/src/index.crates.io-6f17d22bba15001f/tokio-1.37.0/src/sync/rwlock.rs:432:7 | 432 | #[tracing::instrument] | ^^^^^^^ use of undeclared crate or module tracing

Darksonn commented 6 months ago

It looks like you have accidentally modified your local copy of Tokio, because this is how the relevant line of code looks in version 1.37.0 of Tokio:

https://github.com/tokio-rs/tokio/blob/9c337ca1a306be38e3474082be14bdef4bcb45b5/tokio/src/sync/rwlock.rs#L430-L434

I recommend that you delete the tokio-1.37.0 folder in your registry index and let cargo redownload it.

matthiasg commented 6 months ago

@Darksonn i am not aware of changing anything manually in .cargo (how would I?).

Last thing i changed was adding a .cargo/config.toml and ran cargo clean.

But I just came back here anyway to report that deleting the entire cargo registry fixed the issue, so now i just have to find out how that file could have been changed. Thanks

Darksonn commented 6 months ago

I've sometimes seen people modify their registry accidentally when they go-to-definition in their IDE. That might be what happened.

Yup. Happened to me for another repo just yesterday.

matthiasg commented 6 months ago

cargo should make those files readonly by default
