扫描 github.com/golang/protobuf/proto/testdata 时出错：找不到包“.”

Question

在我的项目上运行ning glide install 时，出现以下错误：

[ERROR] Error scanning github.com/golang/protobuf/proto/testdata: cannot find package "." in:
    /Users/bevernie/.glide/cache/src/https-github.com-golang-protobuf/proto/testdata
[ERROR] Failed to retrieve a list of dependencies: Error resolving imports

在查看protobuf的源码时，发现其实并没有这个包。然而，我不直接使用 protobuf，所以错误必须来自我使用的依赖项之一。

当运行在我的项目上宁glide tree时，github.com/golang/protobuf/proto/testdata只有一个实例：

|-- github.com/golang/protobuf/proto   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/proto)
|   |-- github.com/golang/protobuf/proto/test_proto   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/proto/test_proto)
|   |   |-- (Recursion) github.com/golang/protobuf/proto   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/proto)

    github.com/golang/protobuf/proto/testdata   (glide get github.com/golang/protobuf/proto/testdata)

|   |-- github.com/golang/protobuf/proto   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/proto)
|   |   |-- github.com/golang/protobuf/proto/test_proto   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/proto/test_proto)
|   |   |   |-- (Recursion) github.com/golang/protobuf/proto   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/proto)
|   |   |-- (Recursion) github.com/golang/protobuf/ptypes/any   (/Users/bevernie/Programmation/work/src/github.com/golang/protobuf/ptypes/any)

这并不能真正帮助我查明问题的根源。

关于如何解决这些问题，您有什么建议吗？

直到一两周前我的项目编译都很好（我使用 Docker 在生产中部署，所以 glide install 每次都是运行并且在此之前从未失败，而且我最近没有添加任何新的依赖项）。

在你自己之前PR (995), there was glide issue 968

It looks like it's caused by a repository's structure changing, i.e. a sub-package being moved, or removed entirely.

Elliot Wright (seeruk) 提出的解决方法：

If the package that has been updated is under your own control, then I've since found it easier to use some of the newer Go features like type aliases to ease the pain from refactoring.
So, instead of just moving a package, move it and then make aliases to the new location in the old one so that your older code still works.
Then, gradually move things over. Basically just mark things as deprecated but make sure they're still usable for a little while until you've ported new code over.

If the package is not in your control, then you can always clone the version you want manually to your vendor folder and make your updates in your code.
Once you're done, Glide should let you update again.
If it's much more complex, sometimes it's even easier to revert to using go get until you're done updating packages, and rely on your $GOPATH contents.

It's far from ideal, but there are ways you can work around it at least.
In the mean time, I've also made an issue about this on dep.
I think they're looking into a way of disabling this kind of check if you just want the tool to trust you as the developer.

所以您可以使用 godep, or even the bleeding-edge vgo 检查您是否有同样的问题。
