无论我做什么，Vscode IntelliSense 都不适用于 C/C++

Question

我无法让 Vscode 进行语法高亮或完成任何 C/C++ 代码。

• 我使用的是最新的 Vscode（截至撰写本文时为 1.90.1）。
• C/C++ 和 C/C++ 扩展包（最新、非内部版本）已安装并启用。
• 我已经安装并运行了 clang。
• 尝试遵循 Vscode 的官方文档https://code.visualstudio.com/docs/cpp/config-clang-mac

我创建了一个文件夹，使用

code /path/to/my/folder

打开它，有一个空的CPP文件。我正在逐行尝试文档所说的内容。我什至粘贴了文档中的确切代码，但它被识别为“纯文本”，并且没有完成或着色工作：

上面是我的 Vscode 环境，而 Microsoft 的文档很好地突出了语法，代码完成的 C/C++ 文件与我执行的步骤完全相同。在我的例子中，我什至没有在可供选择的语言列表中看到 C 或 C++，它被识别为“纯文本”。

这是我的

}

请注意，

C_Cpp.intelliSenseEngine

设置不存在，但仍然无法正常工作，我在尝试寻找解决方案时添加了它，但似乎没有什么区别。

我还尝试禁用除 C/C++ 之外的所有扩展（并且，在另一个实例中，除了 C/C++ 之外，还有 C/C++ 扩展包）并重新启动 Vscode，但没有任何改变。

我做错了什么？

Answer 1

我通过删除我的

~/Library/Application Support/Code

和

~/.vscode/extensions

目录解决了这个问题（我首先单独尝试了后者但没有成功，然后我也删除了前者）。我不知道是什么导致了这个问题，但我从那里备份了我的

settings.json

，删除了所有内容，重新启动了 Vscode，将

settings.json

放回去，重新启动了 Vscode，安装了 C/C++ 扩展（因为所有扩展也都被删除了） ，问题得到解决。我现在可以在语言列表中看到 C++，并且 IntelliSense 运行良好。
