package 'xxx' is not in GOROOT

项目 go run main.go 时报错

go env 查看环境

如果要用 gopath 模式 引入包 从src目录下开始引入 需要关闭 go mod 模式

export GO111MODULE=off

../github.com/go-playground/universal-translator/errors.go:7:2: cannot find package "github.com/go-playground/locales" in any of:

如果使用go mod 模式

export GO111MODULE=on

并且在目录下执行 go mod init

目录下产生两个文件

go.mod
go.sum

否则就会报错

main.go:15:2: package tinybg/conf is not in GOROOT (/usr/local/go/src/tinybg/conf)
main.go:16:2: package tinybg/utils is not in GOROOT (/usr/local/go/src/tinybg/utils)
