介绍
大略因为 IDE 还不够 智能 & 弱小,在 Rust 中每次须要引入依赖时, 都须要手工增加到 Cargo.toml 文件中, 而且版本号还要去 crates 下面去查 (这个通过装置插件,能够给出提醒版本)
而 cargo-edit 能够主动帮忙增加依赖, 且自动更新版本号
cargo-edit 是一个很好用的工具,扩大了 Cargo 的性能,容许通过命令行批改 Cargo.toml 文件来增加、移除和降级依赖。
cargo-edit 包含几个子命令,如cargo upgrade、cargo add 和 cargo rm 等
。
其中,cargo add
,cargo rm
曾经在最新的 cargo 中集成。
cargo upgrade
用于将 Cargo.toml 中的依赖降级到其最新版本,并提供了不同的降级选项。
cargo set-version
用于在 Cargo.toml 中设置版本号,能够通过指定版本号或主动减少主版本、次版本或修订版原本应用。
如果没有装置 cargo-edit,能够通过cargo install cargo-edit
进行装置
如果有如下报错:
error: linking with `cc` failed: exit status: 1

error: could not compile `cargo-edit` (bin "cargo-upgrade") due to previous error
error: failed to compile `cargo-edit v0.12.2`, intermediate artifacts can be found at `/var/folders/9t/839s3jmj73bcgyp5x_xh3gw00000gn/T/cargo-installhdtjjF`.
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,可依照 cc failed: exit code: 1″>error: linking with cc
failed: exit code: 1 来操作,
即在~/.cargo/config
中(如果没有此文件,则创立), 减少如下内容:
[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
, 胜利装置
应用
以增加某个 crate 为例:
cargo add 须要的库名
再如
