GOPATH之外新建beego项目

配置go mod

Go 1.11，可以将项目放在 GOPATH 之外， 下面的过程就是这样场景的项目建立过程。

$ go mod init archmeasure
go: creating new go.mod: module archmeasure
go: to add module requirements and sums:
        go mod tidy

注意，GOPATH 之外建立项目时， module path 必须有。否则会下面错误

$ go mod init 
go: cannot determine module path for source directory /Users/guohongjun/Documents/MyCodes/arch-measure (outside GOPATH, module path must be specified)

Example usage:
        'go mod init example.com/m' to initialize a v0 or v1 module
        'go mod init example.com/m/v2' to initialize a v2 module

Run 'go help mod init' for more information.

安装或者升级 Beego 和 Bee 的开发工具

$ go get -u github.com/beego/beego/v2
$ go get -u github.com/beego/bee/v2

使用 bee 新建项目

bee 的工具还没兼容GOPATH之外新建项目，需要新建完成后做下面修改：

• 只用一个go.mod , 如果beego不是唯一的项目，需要删除bee默认新建的 go.mod 。
• import 的路径上增加 module path， 比如 默认是 import _ "website/routers" 需要改成 import _ "archmeasure/website/routers"
• default_test.go 中 trace 需要改 import "github.com/beego/beego/v2/core/logs" 把 beego.Trace 改成 logs.Trace 。
