I'm trying to run my C++ program on my Macbook and I'm trying to run my program in VSCode by running the build task C/C++:clang++ build active file .我试图在我的 Macbook 上运行我的 C++ 程序，我试图通过运行构建任务C/C++:clang++ build active file在 VSCode 中运行我的程序。 However, every time I do this I get this error ld: can't open output file for writing: /Users/admin/first/first, errno=21 for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) The terminal process terminated with exit code: 1 However, every time I do this I get this error ld: can't open output file for writing: /Users/admin/first/first, errno=21 for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation) The terminal process terminated with exit code: 1

2 个解决方案

This appears to be a simple permission problem here:这似乎是一个简单的权限问题：

ld: can't open output file for writing ld: 无法打开 output 文件进行写入

The linker cannot write to the file specified. linker 无法写入指定的文件。

Edit : As correctly pointed to by molbdnilo, the error 21 is EISDIR , which means the file you are trying to write to already exists as a directory .编辑：正如 molbdnilo 正确指出的那样， error 21是EISDIR ，这意味着您尝试写入的文件已经作为目录存在。 So... just this folder?所以...只是这个文件夹？ :) :)

Did you brew install any c++ tools?您是否安装了任何 c++ 工具？ Sometimes that is the source of these issues.有时这就是这些问题的根源。 The program is trying to use native OS versions of things when it should use Homebrew's or vice versa.该程序在应该使用 Homebrew 时尝试使用本机操作系统版本，反之亦然。
