rust-analyzer: Failed to load manifest for workspace member

Hello all

I just cloned the repo, and when I run cargo xtask install --server, I get the following error:

error: failed to load manifest at rust-analyzer/xtask/Cargo.toml

Caused by: failed to parse manifest at rust-analyzer/xtask/Cargo.toml

Caused by: feature edition2021 is required

consider adding cargo-features = ["edition2021"] to the manifest

Can someone please help me? I really want to have a rust server up and running because currently, I’m learning rust. Huge thanks to anyone who tries to help! 😃

Okay, I finally got it to work. For those who have the same issue, use this command:

curl https://sh.rustup.rs -sSf | sh

That will, hopefully, install and/or update your rustc version. Thanks for all of your help. I’m going to go ahead and close this issue now, since I found the solution.

I am using the latest version of rustc rustc 1.60.0-nightly (27f5d830e 2022-02-02) but still have the same error

If you’re on Debian/Ubuntu, you should install the toolchain using https://rustup.rs, not the system package.

You will need to update your rustc version. Rustc 1.56 is the oldest currently supported version: https://github.com/rust-analyzer/rust-analyzer/blob/3b3063fb2d1804b3dc42184027ef08073de03fd9/xtask/Cargo.toml#L7
