【问题描述】:
我正在尝试使用 cargo 安装 Racer,所以我在终端中执行了命令 cargo install racer 并导致错误:
error[E0554]: #![feature] may not be used on the stable release channel
--> /home/rajkumar/.cargo/registry/src/github.com-1ecc6299db9ec823/scoped-tls-0.1.2/src/lib.rs:47:34

以下是我的 opensuse 版本详情:

为什么我无法使用 cargo 安装 Racer?我错过了什么吗?

消息说,你必须使用夜间编译器。 github.com/rust-lang-nursery/rustup.rs/blob/master/… 和更多信息,doc.rust-lang.org/book/2018-edition/… 安装后你可以使用
cargo +nightly build
