后端错误：在 Ubuntu 18.10 上构建 SourceKit-LSP 的 llvm.linker.options 无效

Question

我正在关注 this 教程，以便在 Ubuntu 18.10 上集成 Visual Studio Code 和 SourceKit-LSP，但是，我在构建 sourcekit-lsp 项目时遇到了困难。

我得到的错误：

fatal error
: 
error in backend: invalid llvm.linker.options


clang: error: clang frontend command failed with exit code 70 (use -v to see invocation)
clang version 7.0.0-3 (tags/RELEASE_700/final)
Target: x86_64-unknown-linux
Thread model: posix
InstalledDir: /usr/bin
clang: note: diagnostic msg: PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace, preprocessed source, and associated run script.

我不确定它是否相关，但在控制台中输入 Swift 后，我收到以下错误：

Welcome to Swift version 5.0-dev (LLVM b10ce3d642, Clang c1979d7668, Swift 94b167db75).
Type :help for assistance.

如果有人能给我提示如何解决问题，我将不胜感激。我唯一想到的就是重新安装clang，但它并没有解决问题。

这是一个 llvm 错误 (https://bugs.llvm.org/show_bug.cgi?id=39743)。在此处查看解决方法：https://forums.swift.org/t/error-while-trying-to-build-sourcekit-lsp-on-linux/18138/2
