1、下到一半的时候可能会出现错误，这时，编译项目的时候缺少哪个包就去对应的下就好了，guthub上也有一些相对应的包（github源的包都能go get到的）

go get -u -v github.com/stretchr/testify/assert

2、项目会出现”golang.org/x/net/context”丢失，使用间接获取，

go get -u -v github.com/golang/net

在golang.org文件夹下创建x文件夹，将$GOPATH\src\github.com\golang 下的net复制到$GOPATH\src\golang.org\x目录下 ,然后执行：

go install -v golang.org/x/net/context

3、运行时可能会出现找不到包cannot find package “github.com/dgrijalva/jwt-go”

go get -u -v github.com/dgrijalva/jwt-go

再安装一遍echo

go install -v github.com/labstack/echo/
