英文:
Godep restore doesn't use the code saved in _workspace
问题
我一段时间前开始使用godep，但我觉得我没有理解它的原理，可能完全使用错误。
我以为godep会维护_workspace，以便在某些修订版/项目被删除或不可用时，有一个本地副本。但是godep restore似乎根本不使用_workspace。
而且，第二次调用godep save并没有更新_workspace，只更新了Godeps.json。
我错过了什么吗？
更新：
为了解释我的问题，我将Godeps.json中的一个修订版更改为无效的修订版"1"，然后运行了godep restore。以下是我收到的错误信息：
$GOPATH/bin/godep restore
# cd /home/iliga/gopath/src/github.com/jinzhu/gorm; git pull --ff-only
From https://github.com/jinzhu/gorm
a97a508..087b708 master -> origin/master

# cd /home/iliga/gopath/src/github.com/jinzhu/gorm; git checkout 1
error: pathspec '1' did not match any file(s) known to git.
godep: restore: exit status 1
如上所述，我希望不会出现错误，并且godep只会简单地从_workspace中复制代码。
英文:
I started using godep a while ago but I think I'm failing to understand the principal, and I may be using it incorrectly entirely.
I thought godep maintains _workspace in order to have a local copy of the packages in case some revisions/projects are removed or become unavailable. But godep restore doesn't seem to use _workspace at all.
Also, calling godep save for the second time didn't update _workspace, only Godeps.json.
What am I missing?
UPDATE:
To explain my question I changed one of the revisions in my Godeps.json to an invalid revision "1" and ran godep restore. Here's the error I got:
$GOPATH/bin/godep restore
# cd /home/iliga/gopath/src/github.com/jinzhu/gorm; git pull --ff-only
From https://github.com/jinzhu/gorm
a97a508..087b708 master -> origin/master

error: pathspec '1' did not match any file(s) known to git.
godep: restore: exit status 1
As explained above, I would expect there to be no error and for godep to simply copy the code from _workspace.

"godep restore"不使用_workspace。它会读取Godeps.json文件，并将您的依赖项检出到GOPATH中。
要使用_workspace，您需要在go命令前加上godep前缀，例如"godep go build"、"godep go test"。
英文:
"godep restore" does not use _workspace. It reads Godeps.json and check out your dependencies to GOPATH.
To use _workspace, you run go command prefixed with godep, like "godep go build", "godep go test".
