go install报错： should be v0 or v1, not v2问题解决

1. 背景

执行go install时，报错

go install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@latest
-> unzip /Users/albert/go/pkg/mod/cache/download/github.com/golangci/golangci-lint/v2/cmd/golangci-lint/@v/v2.99.1.zip: github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.99.1: invalid version: should be v0 or v1, not v2

2. 排查过程

由于网络上搜不到相关信息，以下通过查看源码的方式排查

2.1. 打开go源码，搜索unzip关键字，找到upzip方法，下面看到日志->和输出的很像，加上sl前缀，重新打包运行查看

2.2. 重新打包

cd src
./make.bash

2.3. 运行

cd /Users/albert/go/go1.21/go1.21.7/bin
./go install github.com/golangci/golangci-lint/v2/cmd/golangci-lint@latest

sl-> unzip /Users/albert/go/pkg/mod/cache/download/github.com/golangci/golangci-lint/v2/cmd/golangci-lint/@v/v2.99.1.zip: github.com/golangci/golangci-lint/v2/cmd/golangci-lint@v2.99.1: invalid version: should be v0 or v1, not v2

2.4. 一步一步多加点日志

2.5. 能发现是cmd/vendor/golang.org/x/mod/zip/zip.go:810处报的错

1. 1. 由于后面还有改动代码，添加注释等，截图和运行结果稍有不匹配

2.6. 由于debug.stack只能打印出本文件的链路，无法自动下钻，定位到checkBip方法后，进到方法里再添加debug.stack

2.7. Check方法

2.8. 写了个单测，SplitPathVersion方法拿到的pathmajor是空字符串

2.9. CheckPathMajor方法里，v为v2.99.1，而pathmajor为空字符串。根据方法里的判断，如果pathmajor为空字符串，那么版本应该为v0或者v1, 而v=v2.99.1,导致报错

3. 原因总结

问题原因在于，SplitPathVersion方法拿到的path是github.com/golangci/golangci-lint/v2/cmd/golangci-lint，解析出来pathMjaor为空字符串，CheckPathMajor方法里判定应该是V0或V1。正确的SplitPathVersion拿到的入参应该是github.com/golangci/golangci-lint/v2，入参没有做处理导致出问题

4. 解决方法

由于这个是go源码的问题，不好直接改动go源码，需要自己写个脚本，下载源代码，使用源代码编译安装
