`go build -mod vendor` 无法使用 vendored 包

`go build -mod vendor` fails to make use of vendored packages

将我的 Go 服务部署到 Google AppEngine(标准)时,我收到一条错误,描述未找到模块版本,但编译一切正常。

模块位于私有 Github 实例上并检出到 vendor/

A go build -mod vendor -o /dev/null ./... 在 cloud-build-local、本地和 Google Cloud Build 中工作。 github 上存在名为 'v1.1.0' 的标签。com/company/gosystem:

A grep -RI 'gosystem@' * 没有任何报告。

Go 使用 https 获取 versions/dependencies。即使你使用 vendor,Go 也会验证版本。由于 github.com/venclave/gosystem 是私人仓库,git 无法访问它。

解决这个问题的方法很少。

1 - 使用 ssh:

git config --global url.ssh://git@github.com/venclave.insteadOf https://github.com/venclave

2 - 使用 GitHub 令牌:

在此处生成 GITHUB_TOKEN https://github.com/settings/tokens

export GITHUB_TOKEN=xxx
git config --global url."https://${GITHUB_TOKEN}:x-oauth-basic@github.com/venclave".insteadOf "https://github.com/venclave"

最后,我通过强制使用 vendor,将其添加到 go.mod:

来完成这项工作
replace github.com/company/gosystem => ./vendor/github.com/company/gosystem
