大概因为IDE还不够智能&强大,在Rust中每次需要引入依赖时,都需要手工添加到Cargo.toml文件中,而且版本号还要去crates上面去查 (这个通过安装插件,可以给出提示版本)
而cargo-edit可以自动帮助添加依赖,且自动更新版本号
cargo-edit是一个很好用的工具,扩展了Cargo的功能,允许通过命令行修改Cargo.toml文件来添加、移除和升级依赖。
cargo-edit包括几个子命令,如cargo upgrade、cargo add和cargo rm等
。
其中,cargo add
,cargo rm
已经在最新的cargo中集成。
cargo upgrade
用于将Cargo.toml中的依赖升级到其最新版本,并提供了不同的升级选项。
cargo set-version
用于在Cargo.toml中设置版本号,可以通过指定版本号或自动增加主版本、次版本或修订版本来使用。
如果没有安装cargo-edit,可以通过cargo install cargo-edit
进行安装
如果有如下报错:
error: linking with `cc` failed: exit status: 1

To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.
可应该是arm64上特有的问题,可按照 error: linking with cc
failed: exit code: 1来操作,
即在~/.cargo/config
中(如果没有此文件,则创建),增加如下内容:
[target.x86_64-apple-darwin]
rustflags = [
"-C", "link-arg=-undefined",
"-C", "link-arg=dynamic_lookup",
]
[target.aarch64-apple-darwin]
rustflags = [
"-C", "link-arg=-undefined",
"-C", "link-arg=dynamic_lookup",
]
再次cargo install cargo-edit
,成功安装
以添加某个crate为例:
cargo add 需要的库名
再如
