为什么我无法使用 cargo 安装 racer?我错过了什么吗?
如错误消息所述,您无法使用稳定的 Rust 编译该代码。您需要安装 nightly Rust,然后使用它来编译程序:
rustup install nightly
cargo +nightly install racer
另请参阅:
- Is it possible to have multiple coexisting Rust installations?
我在尝试使用 armv7-unknown-linux-gnueabihf
的稳定通道编译源代码时收到错误 0554。
由于应用程序使用了稳定版中不可用的功能,所以失败了。
解决方案是安装夜间频道:
rustup install nightly
然后编译:
cargo +nightly build --target=armv7-unknown-linux-gnueabihf
这对我有用。
不要试图遵循 rustup 安装夜间频道时提供的语法,因为它不起作用:
cargo build --target=nightly-armv7-unknown-linux-gnueabihf
