Я попытался развернуть приложение Go в App Engine.У меня следующие ошибки сборки:

Я не могу успешно построить без этих ошибок сборки.Я попытался точно следовать документации для Go на App Engine, и я растерялся, если мне нужно структурировать свое приложение иначе, чем предполагалось.Любые мысли о том, как решить эту ошибку GOPATH?
