VSCode-有一条红色下划线，但程序构建和运行正确，并且出现了dubugging错误 我已经配置了我的VSCODE，在Linux上使用C++。最近我想编写一个新的cpp程序，我遵循了MS VScode教程，但当我将代码复制到VScode时，会出现一条红色下划线和如下提示： ,c++,visual-studio-code,C++,Visual Studio Code,但是，我可以构建它，甚至可以无误地正确运行它： 当我调试它时，会发生错误 { "resource": "/home/aqachun/Documents/Projects/cpp/vscodeTest/helloworld.cpp", "owner": "C/C++", "severity": 8, "message": "no instance of constructor \"std::vector<_Tp, _Alloc>::vector [wit

看起来像是一个智能感知错误。这个错误实际上是一个构建失败，所以你声称你可以构建肯定是一个误解。至少我是这么想的。如果你描述你所做的和你所观察到的，人们可以给出更好的诊断。作为一个新用户，也请阅读。@UlrichEckhardt谢谢，我已经用两张关于运行构建任务和运行程序的图片更新了我的问题，它似乎运行得很好吗？有趣的是，这对我来说很好，使用clang++-9I，我在VSCode中也没有收到类似intellisense错误的错误。该错误实际上是一个构建失败，所以你所说的你可以构建一定是一种误解。至少我是这么想的。如果你描述你所做的和你所观察到的，人们可以给出更好的诊断。作为一个新用户，也请阅读。@UlrichEckhardt谢谢，我已经用两张关于运行构建任务和运行程序的图片更新了我的问题，它似乎运行得很好吗？有趣的是，这对我来说很好，使用clang++-9I我在VSCode中也没有这样的错误谢谢，我尝试将

更改为

，我得到一个
#include检测到的错误。请更新您的includePath，当单击灯泡以添加其所说要添加的includePath时，再次显示原始错误。也许我应该配置我的c/cpp扩展？检查你是否有clang（你可以很容易地在Linux上安装它）只要转到

如果你安装了它，如果不转到
sudo apt get install clang
