golang 1.12导入相对目录模块

Question

go 1.12 如何导入相对路径模块。例如

demo_project
   - main.go
   -- demo
      - demo.go


demo.go:
pakcage demo
...

我尝试在main.go中导入“./demo”，但是报错:找不到路径 _/home/xxx/mywork/go_project/grpc_demo/demo 的模块如何在main.go中导入demo

Answer 1

• GO 首先要从 $GOPATH env 导入包。如果 go 找不到包，则会引发错误。

• 将我们的项目目录添加到 $GOPATH 环境中。

debug@ulab:/tmp/test$ go run main.go
main.go:3:8: cannot find package "mylib" in any of:
    /home/debug/.golang/go/src/mylib (from $GOROOT)
    /home/debug/.golang/gopath/src/mylib (from $GOPATH)

$ tree
.
├── main.go
├── src
│   └── hello
│       └── hello.go
└── start.sh

2 directories, 3 files

---

$ cat start.sh
#!/bin/sh

GOPATH="$(pwd):$(go env GOPATH)"

go run main.go

---

$ ./start.sh
