我想用 C++ 编译我的“hello world”,但我不能。 我使用 Visual Studio Code,这是我的代码。
当我尝试构建 cpp 时,错误是:
clang: error: no such file or directory: '/Users/a1/C++/first'
我的文件是“/Users/a1/C++/first.cpp”
这适用于 macOS、High Sierra 10.14 和 Visual Studio 代码。
我安装了 C/C++,但现在无法构建我的 C++。
#include "stadfx.h"
#include < iostream >
int _tmain(int argc, _TCHAR* argv[]) {
std::cout <<"Hello, World" <<std::endl;
return 0;
}
Executing task: g++ /Users/a1/C++/first.cpp -o -g /Users/a1/C++/first <
clang: 错误: 没有这样的文件或目录: '/Users/a1/C++/first' 터미널 프로세스가 종료 코드 1(으)로 종료되었습니다.

最佳答案
-o 选项需要一个文件名,它应该紧跟在“-o”之后。您已将“-g”作为文件名。然后命令以要编译的文件结束。在您的情况下,“第一”(不存在)。
尝试将您的 json 文件中的顺序移动为如下内容:
"args": [
"-g",
"-o",
"${fileDirname}/${fileBasenameNoExtension}",
"${file}"
],
