我想使用这个包:github.com/go-sql-driver/mysqlgo get -u github.com/go-sql-driver/mysqlmain.go:12:2: no required module provides package github.com/go-sql-driver/mysql: go.mod file not found in current directory or any parent directory; see 'go help modules'
之前我不知道在终端中从零创建一个项目,我创建了一个文件夹,cd到其中,然后运行go mod init my_project_name,为我创建一个go.mod文件,然后我创建了main.go文件,该文件构建得很好cannot determine module path for source directory /Users/berkcan/workspace/go/my_project_name (outside GOPATH, module path must be specified)
