Rake db:migrate返回"rake已中止！没有这样的文件可加载-- spec“

Question

出于某种原因，rails开始给我一个关于"rake db:migrate“的错误，并且我不能再运行迁移。它返回错误“没有这样的文件要加载-- spec /home/ti/rails_apps/appname/Rakefile:10”

我花了两个小时在谷歌上搜索答案，试图找出答案，但一无所获。可能的问题是什么？

下面是跟踪信息：

Answer 1

也许是你的谷歌地理编码器插件rake任务需要一些你没有的东西？

/home/ti/rails_apps/teamisrael/vendor/plugins/google-geocoder/tasks/rspec.rake:5

Answer 2

看起来在堆栈跟踪中，google-geocoder插件需要旧版本的RSpec。
