为什么 `cargo build` 不能在 VS Code 中编译 structopt-derive？
Why can't `cargo build` compile structopt-derive in VS Code?
我正在尝试使用 Rust 和出色的 structopt crate 编写一个小型 CLI 应用程序。
当我使用 Notepad++（编写代码）和 Conemu（运行 Cargo 命令）时，一切正常。
但是，当我将 VS Code 与 Rust plugin（或 Eclipse Corrosion）一起使用时，cargo build 命令失败并出现此错误

问题是什么？我可以做什么 - 除了使用 Notepad++ 编码 - 能够 运行 VS Code 中的 cargo 命令？
似乎是 RLS 中的错误：Windows: RLS keeping derive plugin DLLs opened prevents cargo build from working #802
Whenever the RLS is running for a crate, I can't do cargo build for that crate. It fails with errors like this:
[...]
Looking in Process Explorer, RLS has the derive plugin DLLs loaded. I assume this is what's causing cargo to fail, since it can't write to those files while they're loaded. Similarly, cargo clean fails:
[...]
If I close VSCode (and thus RLS), building with cargo build works fine again.
I assume this is Windows-specific due to its file exclusivity behavior. I think this started happening with a recent nightly (3/28?). I suppose this could've been caused by some change in cargo or rustc causing it to write to dlls which were already built or something.
因此解决方案应该非常简单：将 RLS 更新到其最新版本并查看已修复的错误！
而要更新 RLS，只需 rustup update
