google-app-engine - 去 appengine : panic: proto: duplicate enum registered: appengine. LogServiceError_ErrorCode

Question

我最近更新了我的 golang GAE SDK(goapp 版本现在是 go1.4.2 (appengine-1.9.21) darwin/amd64)，现在我在尝试提供该应用程序时遇到此错误:

orcaman$ goapp version
go version go1.4.2 (appengine-1.9.21) darwin/amd64

Ors-MacBook-Pro:main orcaman$ goapp serve

看完this ，我虽然这可能与同时引用新的“google.golang.org/appengine”和旧的“appengine”包有关，但我的应用程序现在没有对“appengine”的单一引用。

帮助？

好的，我明白了:我必须删除我的 $GOPATH/src/google.golang.org/appengine/文件夹，然后从我的应用程序重新运行 goapp get 以重新获取新格式的 deps。这解决了上述问题。
