warning: go env -w GOPRIVATE=... does not override conflicting OS environment variable 设置环境变量失败

问题现象

设置环境变量失败

[root@centos7 ~]# go env -w GOPRIVATE="git.test.com"
warning: go env -w GOPRIVATE=... does not override conflicting OS environment variable

有可能GONOPROXY、GONOSUMDB等也会失败且错误信息一样。

问题原因

是和原有的配置有冲突

#原有go env信息如下：
[root@centos7 ~]# go env
GO111MODULE="on"
GOARCH="amd64"
GOBIN=""
GOCACHE="/root/.cache/go-build"
GOENV="/root/.config/go/env"
GOEXE=""
GOEXPERIMENT=""
GOFLAGS=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOINSECURE=""
GOMODCACHE="/root/project/pkg/mod"
GONOPROXY="git.work.com"
GONOSUMDB="git.work.com"
GOOS="linux"
GOPATH="/root/project"
GOPRIVATE="git.work.com"

解决方法

通过unset命令删除环境变量，然后在设置

[root@centos7 ~]# unset GOPRIVATE
[root@centos7 ~]# go env -w GOPRIVATE="git.test.com"
#更新后的env信息如下：
[root@centos7 ~]# go env
GO111MODULE="on"

GOENV="/root/.config/go/env"
