error: could not compile `ra_ap_ide` due to previous error
warning: build failed, waiting for other jobs to finish...
error: failed to compile `cargo-modules v0.6.0`, intermediate artifacts can be found at `/var/folders/bb/7_6236wd3y9b5_wy_6v2_tv40000gn/T/cargo-installdq0M5j`

However, it can be installed without error if I use the older version which is 0.5.14.

Same problem here. I'm using Ubuntu 22.04

It looks like you're not on the latest version of Rust. You will need to upgrade to Rust 1.65, which stabilized if-let statements.
