go - 尝试通过 vendor 目录部署Google Cloud功能时出错

Question

我尝试了go113和go111，但是它们都不起作用:

目录结构如下:

cool_project
   - func.go
   - func_test.go
   utility
     - helper.go
   fancy
     - fancy.go
   go.mod # module cool_project
   go.sum
   .gcloudignore
   vendor
     ...

当我尝试使用gcloud functions deploy ...进行部署时，失败并显示:找不到软件包cool_project/utility或cool_project/fancy。

我不得不尝试使用Vendor ebcause，因为go.mod随INVALID_ARGUMENT不断失败，所以在有人围着谷歌搜索后指出了这个article

注意:

如果我使用go111和go.mod文件(无供应商目录)进行部署，它将失败，并出现隐含错误:

Deploying function (may take a while - up to 2 minutes)...failed.

对于go113和go.mod文件，它根本没有给出有用的错误:

日志显示:

INVALID_ARGUMENT

冉部署cmd:

叹! FWIW我确实测试了单元测试，并且go113可以正常工作。

Answer 1

我发现了2种(非常hacky)解决此问题的方法。我的特殊情况是我有一个GCP无法访问的 private 存储库。他们说我需要在此页面底部(今天)创建一个供应商目录:
https://cloud.google.com/functions/docs/writing/specifying-dependencies-go
所以我做到了，但是后来我得到了上面报告的错误。
错误解决方案1:
将所有内容放在主目录中，然后将每个包重命名为入口点函数的包名称。
Hacky解决方案2:
从字面上看，这是错误的第一行:

DEBUG: (gcloud.functions.deploy) OperationError: code=4, message=Build failed: srv/gopath/src/p/vendor/gcpfun/func.go:21:2: cannot find package "cool_project/fancy" in any of:
    /tmp/staging/srv/gopath/src/p/vendor/vendor/cool_project/fancy (vendor tree)

在这种情况下，请执行以下操作:

go mod vendor

然后在供应商目录中创建一个文件夹，其名称为go mod软件包名称，在您的情况下为'cool_project'。然后将subdir文件夹复制并粘贴到该目录中(例如vendor/cool_project/fancy/*.go)，然后再次进行部署。
