go.mod关于go版本异常的处理

​
1.私有仓库
 go.mod   要注意module的配置mod地址，要与下载地址一致。 否则就算下载下来，就会比较后报错。

module test.com/devGroup/devProjectgo 1.22.2

     2. 代码中的包引用地址。  要与module中的mod路径一致

package mainimport ("module test.com/devGroup/devProject/auth")func main() {auth.VerifyPassword("a","b")}

2.  三方代码引用
1.  私有库的拉取配置，有三种方式

 ssh
私钥放在本地： 用户/.ssh/  的目录中。

如：C:\Users\cdh01\.ssh

       2.访问令牌

      3.帐号和密码

3.  常见报错
1.https下载，报证书错误。

解决方式：

临时绕过：git config --global http.sslVerify false

或采用git@的方式进行下载

2. 对于奇怪的私有域名不识别。

        server response: not found: test.com/devGroup/devProject@v0.0.0-20250506075833-7f2f4412776b: unrecognized import path "test.com/devGroup/devProject": https fetch: Get "https://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1test.com/devGroup/devProjecthttps://test.com/devGroup/devProjec?go-get=1": dial tcp: lookup git.dbu.test on 8.8.8.8:53: no such host

原因： 是默认下载包走了代码。

解决方式：

配置为私有库就不走代理了  go env -w GOPRIVATE=test.com/devGroup/devProject

3. 下载地址与私有库mod.module配置的地址不一致，导致异常。

go: finding module for package test.com/devGroup/devProject/auth

go: downloading test.com/devGroup/devProject v0.0.0-20250506075833-7f2f4412776b

        module declares its path as: aa.test.com/aa-devProject

                but was required as: test.com/devGroup/devProject

4.下载异常

go mod tidy

go: test_license imports

        10.251.24.113:2222/devGroup/devProject/auth: malformed import path "10.251.24.113:2222/devGroup/devProject/auth": invalid char ':'

原因：git@的host必须用域名，不能用IP要端口的方式。

解决方式：采用https的下载方式。

或通过配置来实现动态的切换 git config --global url."[e-mail]:".insteadOf "https://test.com"

​

其他：

三者的关系

变量	功能	典型值	是否必须
GOPRIVATE	定义私有模块	*.test.com	✅ 是（主开关）
GONOPROXY	私有模块不走代理	*.test.com	可选（默认继承 GOPRIVATE）
GONOSUMDB	私有模块不校验 checksum	*.test.com	可选（默认继承 GOPRIVATE）

如果只设置 GOPRIVATE，Go 会自动让 GONOPROXY 和 GONOSUMDB 与其保持一致。
但如果需要更精细控制（例如某些模块走代理但跳过 checksum），可以单独设置。
