记录一次go mod tidy/go get安装私库错误信息

执行语句

go get -u codeup.aliyun.com/xxxx/commonlib

错误信息如下

go: codeup.aliyun.com/golang-base/commonlib@v1.0.4 (replaced by codeup.aliyun.com/go/commonlib@v1.0.4): verifying go.mod: codeup.aliyun.com/go/commonlib@v1.0.4/go.mod: reading https://goproxy.cn/sumdb/sum.golang.org/lookup/codeup.aliyun.com/go/commonlib@v1.0.4: 404 Not Found

解决方式

问题原因是没有权限访问这个，如果是阿里云的codeup平台，需要再用户目录下添加_netrc文件

路径：C:\Users\Administrator\_netrc

加了上面还是没用，并且提示

https://goproxy.cn/sumdb/sum.golang.org/lookup/codeup.aliyun.com/go/commonlib@v1.0.4: 404 Not Found

这很明显，走了代理去拉取私库，设置不走代理即可,可以设置多个值，以逗号隔开

私有仓库记得打tag，比如v1.0.0,如果没有打tag，可以用master替代

windows:
$env:GOPRIVATE = "codeup.aliyun.com,git.my.com/private"

linux:
export GOPRIVATE=codeup.aliyun.com,git.my.com/private

更新代码

如果没有打tag，需要将原来生成的随机tag修改为master或者其他的分支即可

有tag的话，就更改为新的tag即可

题外（忽略不看）：设置GOPROXY

windows:
添加： go env -w GOPROXY=https://goproxy.cn

linxu:
export GOPROXY=https://goproxy.cn,direct

取消代理：
go -u GOPROXY

另外一种错误

go: errors parsing go.mod:
/service/go.mod:41: unrecognized import path "codeup.aliyun.com/xxx/protobuf": parse https://codeup.aliyun.com/xxx/protobuf?go-get=1: no go-import meta tags ()

解决方式：在go mod中找到私有仓库地址，看结尾是否是.git，没有就加上
