VSCode-有一个红色下划线，但程序构建和运行正确，并且出现配音错误

Question

我已经将vscode配置为在Linux上使用c++。最近我想写一个新的cpp程序，我遵循了MS VScode教程，但当我将代码复制到VScode时，会有一个红色下划线和提示，如下所示：错误

然而，我可以构建它，甚至可以正确运行它而不会出错：运行构建任务在终端中运行它

当我调试它时，会发生错误。

"owner": "C/C++",
"severity": 8,
"message": "no instance of constructor "std::vector<_Tp, _Alloc>::vector [with _Tp=std::string, _Alloc=std::allocator<std::string>]" matches the argument list -- argument types are: (const char [6], const char [4], const char [6], const char [5], const char [8], const char [23])",
"startLineNumber": 9,
"startColumn": 24,
"endLineNumber": 9,
"endColumn": 24
}

这是我的c_cpp_properties.json:

{
"configurations": [
{
"name": "Linux",
"defines": [],
"compilerPath": "/usr/bin/gcc",
"includePath": [
"${default}",
"/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../include/c++/9.2.0",
"/usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../include/c++/9.2.0/x86_64-pc-linux-gnu",

"/usr/include"
],
"cppStandard": "c++17",
"cStandard": "c11"
}
],
"version": 4
}

和我的代码：

#include <iostream>
#include <vector>
#include <string>
using namespace std;
int main()
{
vector<string> msg {"Hello", "C++", "World", "from", "VS Code", "and the C++ extension!"};
for (const string& word : msg)
{
cout << word << " ";
}
cout << endl;
}

我也做了那个教程(针对Linux(，没有这样的错误。这是我的c_cpp_properties.json文件，我想可能是因为您没有指定IntelliSense。试试我的c_cpp_properties.json:

{
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**"
],
"defines": [],
"compilerPath": "/usr/bin/gcc",
"cStandard": "c11",
"cppStandard": "c++17",
"intelliSenseMode": "clang-x64"
}
],
"version": 4

}

这是我的设置。json:

"array": "cpp",
"atomic": "cpp",
"*.tcc": "cpp",
"cctype": "cpp",

我的启动json:

也许更改这些设置文件会有所帮助。矿山作业
