rustup update 升级rust时异常 directory does not exist: ‘share/doc/rust/html‘ 解决方法

最近把原来的老版本rust升级为最新版本, 转悠了半天给我报一个 目录不存在异常而升级失败。

异常信息:

**info:**rolling back changes

**error:**failure removing component 'rust-docs-x86_64-apple-darwin', directory does not exist: 'share/doc/rust/html'

stable-x86_64-apple-darwin update failed - rustc 1.70.0 (90c541806 2023-05-31)

解决方法:

mac系统下rust的安装路径在 ~/.rustup/toolchains/stable-x86_64-apple-darwin , 进入这个目录然后手动创建提示不存在的这个目录 share/doc/rust/html , 然后在重新执行 rustup update 即可

网上其他的解决方法: 重新安装rustc, 命令如下:

bash 复制代码
# 重新安装rustc
rustup component remove rustc

rustup component add rustc


# 重新执行rust更新
rustup update

Rust升级和验证

bash 复制代码
