i got a test case failed

org.rust.cargo.commands.CargoTestCase > testCargoMetadata FAILED
    com.intellij.execution.ExecutionException: No metadata subcommand, please update cargo
        at org.rust.cargo.commands.Cargo.execute(Cargo.kt:76)

        at org.rust.cargo.commands.CargoTestCase.testCargoMetadata(CargoTestCase.kt:11)

and i currently get

• rustc 1.6.0
• cargo 0.8.0 (28a0cbb 2016-01-17)

how can i fix it.

You can update cargo :) cargo 0.9.0-nightly (6c05bcb 2016-01-29) is the minimal version, which has metadata command.

This particular test picks cargo from $PATH and is skipped if cargo is not found. So if you don't want to update cargo, it's fine just to remove it from PATH, or just change this condition to true.

👌 thx :)

[zjhmale]

but i find latest version of cargo is 0.8.0 https://github.com/rust-lang/cargo/releases @matklad

[matklad]

Yes, 0.9.0 is a yet-to-be release nightly version (it will hit stable with Rust 1.8). You can install it with multirust (nightly toolchain), or from a tarball linked in Cargo's readme.

thx! i just upgrade cargo to 0.9.0-nightly (8fc3fd8 2016-02-29) and fix it.
