如何使sourcekit-lsp为VS代码工作？(用于Swift)

Question

我一直在尝试用VS代码设置Swift开发，为了做到这一点，我一直在遵循本教程：在Linux上使用Visual代码进行快速开发！，但是在完成它之后，我遇到了一个问题，说它无法启动SourceKit语言服务器。它还表示不能使用命令sourcekit-lsp启动服务器。

仍未解决，执行swift build -Xcxx -I/home/nikko/swift/swift-5.2.4-RELEASE-ubuntu20.04/usr/lib/swift时会得到以下信息

(顺便说一句，是44/52。每次都没有完成)

奇怪的是，我在谷歌上找不到任何有用的“_spi”(除了它可能意味着串行外设接口)。

在找到并遵循本指南之后：https://www.raywenderlich.com/8325890-a-complete-guide-to-swift-development-on-linux

我发现我必须在项目文件夹中编写rm -rf .build/，因为如果该文件夹已经存在，sourcekit-lsp就会失败。

还不够，我有未知属性'_spi‘的问题
