vscode中出现$GOPATH/go.mod exists but should not

这个问题通常出现在Go项目中，因为Go1.11版本之后，Go modules被引入，它是一个新的依赖管理机制，会自动从远程下载依赖项，而不需要在本地安装它们。解决方法如下：

1. 打开终端并进入项目目录。
2. 运行命令：`go mod init your-project-name`。这会创建一个go.mod文件。
3. 运行命令：`go mod tidy`，这会根据代码导入的包来更新依赖关系。
4. 最后，删除$GOPATH/go.mod文件即可。

go.mod exists but should not

这个错误提示意思是说 go.mod 文件存在，但实际上不应该存在。可能是因为你的项目不需要使用 Go Modules，或者你的项目已经使用了其他的依赖管理工具，比如 dep 或者 glide。解决方法是删除 go.mod 文件，或者将项目迁移到 Go Modules。

cannot open output file D:\vsCode\CPP/exe/test1.exe: No such file or directory

This error message indicates that the program is unable to create the output file because the directory specified does not exist or the file cannot be created due to some permission issues.

To resolve this issue, you can try the following steps:

1. Make sure that the directory specified in the output file path exists. If not, create the directory manually.
2. Check if there are any permission issues with the directory or file. Ensure that you have the necessary permissions to create files in the specified directory.
3. If you are using an antivirus program, temporarily disable it and try running the program again. Sometimes, antivirus programs can interfere with the creation of new files.
4. If none of the above steps work, try changing the output file path to a different directory or location.

Once you have resolved the issue, you should be able to create the output file without any errors.
