Vscode-rust: rust-analyzer 崩溃：无法反序列化 InitializeParams：缺少字段“请求”

Rust-analyzer 发布 2020-08-31 是片状的。 它只是在我的 VSCode 安装中停止工作。 它完成代码完成并显示文档弹出窗口，但停止显示编译器错误和警告。 重启 VSCode 没有效果。 rustup update没有修复它。

有没有什么办法可以使用VSCode来编辑使用tokio的代码？ 是否一切都被破坏了，或者是否有 VSCode、VSCode Rust 扩展、RLS/rust-analyzer 和 rust-analyzer 版本的特定组合可以正常工作？

VSCode + just rust-analyzer 在 MacOS 上对我有用。

Windows 上同样的问题

@Calvin-he、@ mleonhard如果您使用的是 Rust 扩展，我建议您切换到rust-analyzer一个。 前者的rust-analyzer支持有点过时，用户似乎遇到了很多问题。

我认为这是通过更新 rust-analyzer VS Code 插件的版本来解决的。 我认为这是一个上游问题，但我没有进一步调查： https :

我有同样的“无法反序列化 initializeParams ...” 来自 rust-analyzer 的错误。 VS Code 报告说，每当我打开一个新的.rs文件时，它就会“在过去 3 分钟内崩溃 5 次”。

我在远程主机上安装了（带星号的）“Rust”扩展 v0.7.8（并将 rust-analyzer 设置为引擎）和 rust-analyzer 扩展。 禁用“Rust”扩展使问题消失。 很难判断是哪个锈蚀分析仪崩溃了。 显然它是由“Rust”扩展安装的，而不是“rust-analyzer”扩展。

对于后代，我正在运行：
VS Code：1.50.1（在 macOS 10.15.7 上，但连接到运行 Ubuntu 20.04 的远程主机）
Rust-analyzer 扩展：v0.2.344

哇，谢谢@benjaminfjones ，这是一个有趣的失败模式！

谢谢@benjaminfjones ，禁用“Rust”扩展成功了！ （对于相同的版本）。

如果禁用 Rust 扩展，代码补全如何工作？

@abhyuditjain rust-analyzer自己完成代码。 它完全替代了 Rust 扩展。

我有同样的问题（见下面的日志）：我禁用了 rust-analyzer 扩展，rls 工作正常。

你在跟我讲话吗？

@沃尔克-韦斯曼你禁用rust-analyzer扩展或实验rust-analyzer的支持vscode-rust ？ 后者有些损坏，但独立的rust-analyzer扩展应该可以工作。

我不知道我两个月前做了什么。 目前，vscode.rust 已“内置”并启用，而 matklad.rust-analyzer
已安装并启用。 rust-lang.rust 被禁用。

ps -ef | grep -i rls什么也没显示。 ps -ef显示/home/volker/.config/Code - OSS/User/globalStorage/matklad.rust-analyzer/rust-analyzer-x86_64-unknown-linux-gnu正在运行。

我不知道这是否是我 2 个月前的配置，但它似乎有效（除了 self.hl_range.range.contains_range(hl_range.range)、crates/ide/src/syntax_highlighting/highlights.rs 中的断言失败之外:42:9 ，但我这是一个不同的错误。）。

目前，vscode.rust 已“内置”并启用，并且 matklad.rust-analyzer 已安装并启用。 rust-lang.rust 被禁用。

然后你使用rust-analyzer 。

self.hl_range.range.contains_range 中的断言失败

那可能是https://github.com/rust-analyzer/rust-analyzer/issues/7299。

是的。 但是我不知道这是否是我最近两个月的配置。
