go get报错：zip: not a valid zip file

具体报错：

User@3-WIN10BG0088 MINGW64 /d/Users/WorkSpace/Go/projects/gin-study
$ go get github.com/gin-gonic/gin
go: downloading github.com/gin-gonic/gin v1.9.1
go: github.com/gin-gonic/gin: zip: not a valid zip file
User@3-WIN10BG0088 MINGW64 /d/Users/WorkSpace/Go/projects/gin-study
$ go env | grep PROXY
set GONOPROXY=
set GOPROXY=https://mirrors.aliyun.com/goproxy/,direct

解决方式：

方式1：执行 go clean -modcache清理缓存（无效）

User@3-WIN10BG0088 MINGW64 /d/Users/WorkSpace/Go/projects/gin-study
$ go clean -modcache
User@3-WIN10BG0088 MINGW64 /d/Users/WorkSpace/Go/projects/gin-study
$ go mod tidy
go: finding module for package github.com/gin-gonic/gin
go: downloading github.com/gin-gonic/gin v1.9.1
go: github.com/ice-fire-song/gin-study imports
        github.com/gin-gonic/gin: zip: not a valid zip file

方式2：更换GOPROXY为七牛云的go代理（有效）

User@3-WIN10BG0088 MINGW64 /d/Users/WorkSpace/Go/projects/gin-study
$ go env -w GOPROXY="https://goproxy.cn,direct"
User@3-WIN10BG0088 MINGW64 /d/Users/WorkSpace/Go/projects/gin-study
$ go env|grep PROXY
set GONOPROXY=
set GOPROXY=https://goproxy.cn,direct
