go build报错，提示错误can‘t load package： package xxx is not in GOROOT

我修改了一下 go.mod 文件 

lic_req 改成了 lic_req0506

 

module lic_req0506

go 1.17

require (
    github.com/farmerx/gorsa v0.0.0-20161211100049-3ae06f674f40
    github.com/gin-gonic/gin v1.7.7

 编译就不行了：

PS C:\code\luok\requesttoolgo> go build
main.go:10:2: package lic_req/httpUtils is not in GOROOT (C:\Program Files (x86)\Go\src\lic_req\httpUtils)
main.go:11:2: package lic_req/securityUtils is not in GOROOT (C:\Program Files (x86)\Go\src\lic_req\securityUtils)

 

检查发现有错误：

 

 

 

 

为什么啊！

找了一大圈都不行！

 

看看环境变量：

PS C:\code\luok\requesttoolgo> go env

set GO111MODULE=
set GOARCH=386
set GOBIN=
set GOCACHE=C:\Users\luok\AppData\Local\go-build
set GOENV=C:\Users\luok\AppData\Roaming\go\env
set GOEXE=.exe
set GOEXPERIMENT=
set GOFLAGS=
set GOHOSTARCH=386
set GOHOSTOS=windows
set GOINSECURE=
set GOMODCACHE=C:\Users\luok\go\pkg\mod
set GONOPROXY=
set GONOSUMDB=
set GOOS=windows
set GOPATH=C:\Users\luok\go
set GOPRIVATE=
set GOSUMDB=sum.golang.org
set GOVERSION=go1.18.1
set GCCGO=gccgo
set AR=ar
set CC=gcc
set CGO_CFLAGS=-g -O2

 

PS C:\code\luok\requesttoolgo> go env GOROOT
C:\Program Files (x86)\Go

 

go mod 问题？

重新初始化一下：

PS C:\code\luok\requesttoolgo> go mod init
main.go:10:2: package lic_req/httpUtils is not in GOROOT (C:\Program Files (x86)\Go\src\lic_req\httpUtils)
main.go:11:2: package lic_req/securityUtils is not in GOROOT (C:\Program Files (x86)\Go\src\lic_req\securityUtils)
PS C:\code\luok\requesttoolgo> go build
main.go:10:2: package lic_req/httpUtils is not in GOROOT (C:\Program Files (x86)\Go\src\lic_req\httpUtils)
main.go:11:2: package lic_req/securityUtils is not in GOROOT (C:\Program Files (x86)\Go\src\lic_req\securityUtils)
PS C:\code\luok\requesttoolgo>
PS C:\code\luok\requesttoolgo> go mod tidy
PS C:\code\luok\requesttoolgo>
PS C:\code\luok\requesttoolgo> go mod init
go: C:\code\luok\requesttoolgo\go.mod already exists

 

还是不行啊！go mod 模式改为传统模式：

PS C:\code\luok\requesttoolgo> go env -w GO111MODULE=   

或者

PS C:\code\luok\requesttoolgo> go env -w GO111MODULE=off

 

也是不行：

PS C:\code\luok\requesttoolgo> go build
main.go:17:2: cannot find package "github.com/gin-gonic/gin" in any of:
C:\Program Files (x86)\Go\src\github.com\gin-gonic\gin (from $GOROOT)
C:\Users\luok\go\src\github.com\gin-gonic\gin (from $GOPATH)
main.go:10:2: cannot find package "lic_req/httpUtils" in any of:
C:\Program Files (x86)\Go\src\lic_req\httpUtils (from $GOROOT)
C:\Users\luok\go\src\lic_req\httpUtils (from $GOPATH)
main.go:11:2: cannot find package "lic_req/securityUtils" in any of:
C:\Program Files (x86)\Go\src\lic_req\securityUtils (from $GOROOT)
C:\Users\luok\go\src\lic_req\securityUtils (from $GOPATH)

 

改回去吧：  PS C:\code\luok\requesttoolgo> go env -w GO111MODULE=on

 

 

后面终于解决了！！发现， 就是 需要go.mod 文件里面的 module 和 import 里面的保持一致！

 

 

 

 

go.mod 文件里面的 module 字段不能随便改！
