抱怨我每晚都需要 rust

抱怨 skipping nightly which is missing installed component 'rls'，我不知道如何解决这个问题
如有任何帮助，我们将不胜感激
抱歉，文字太长，如果您只想快速修复，请参阅下面的您的问题的解决方案。您也可以查看 the rustup book，它包含有关此类问题的信息。
您正在尝试安装 Rust 的夜间版本。在夜间版本中，Rust 的非必要组件的可用性，例如 Rust Language Server (or short rls) is not guaranteed – if they fail to build, the nightly is shipped without them. You can see here that rls indeed was not part of the last few nightlies. The last day a nightly was shipped with rls was 2021-05-18, which is a build from the day before, so 2021-05-17 (a bit irritating, but this seems to be accepted behavior).
您的 rustup 安装似乎配置为包括 rls。因此，当您告诉 rustup 更新您的 nightly 工具链时，rustup 会选择包含 rls 的最新夜间 。没有比您当前安装的 nightly-2021-05-17 更新的 nightlies，因此，rustup 不会更新工具链。
您的问题的解决方案
- 如果您不需要
rls（只有在 IDE 和类似的东西中自动完成才需要），您的问题有多种解决方案：
- 您可以从夜间工具链中删除
rls 组件：rustup component remove --toolchain nightly rls
- The rustup book还有一些解决办法：
If [a previously installed component] is missing, rustup will automatically search for an older release that contains the required components. There are several ways to change this behavior:
- Use the --force flag to rustup toolchain install to force it to install the most recent version even if there is a missing component.
- Use the --profile flag to rustup toolchain install to use a different profile that does not contain the missing component. For example, --profile=minimal should always work, as the minimal set is required to exist. See the Profiles chapter for more detail.
- Install a specific date that contains the components you need. For example, rustup toolchain install nightly-2020-07-27. You can then use overrides to pin to that specific release.
- 如果您确实需要
rls，您就有点为难了。您可能想要 use a override 用于您的项目，实际上使用不同的 Rust 构建来构建您的代码和 运行 rls。然而，这可能行不通——rls 可能需要为自动完成构建你的项目依赖项，而 Rocket 不允许使用较旧的 nightlies。对于这种情况，我真的没有解决方案——您可能需要继续使用旧版本的 Rocket 或暂时停止使用 rls，直到有更新的 Rust 每晚发布 rls。
