help： go build 失败，提示 usage: compile [options] file.go...

[codists]

一、说明

GOROOT=D:\apps\go1.18
GOPATH=D:\GoProject 

二、问题描述

在 D:\GoProject\src\power\project_name\cmd\listener> 目录下执行 go build 命令(说明：project 是 项目名称):

\GoProject\src\power\project\cmd\listener>go build .\main.go

结果编译失败，提示信息如下：

说明：(1)错误提示中第一行的 auto-task/task/create 是项目的目录。

二、尝试的解决方法

1.修改 project 上一级目录名称，如 power 修改为 power1,结果可以正常编译。  
2.将 project 移动到 GoProject 之外的目录，结果可以正常编译。  

请教各位大佬，为什么用 power 这个名字就不行，可能是因为什么原因造成的？

第二个就是答案，自从有了 go mod 之后，不要把项目放到 gopath 目录下，gopath 在 go mod 之后就是个缓存目录，里面的文件也尽量不要编辑。

我估计你的 go mod 文件 第一行有包含 .../power/project/... ，go 编译时会查找 gopath 目录下的代码也会查找 go.mod 文件开始的子目录路径，而你把项目放到 gopath 目录下，估计引起了冲突。把 power 改为 power1 后，如果你的 go.mod 文件没有同步更改，那么 go 在查找路径时不会冲突，所以第一个也能编译（这个是我推测的）
