我反复遇到这个问题。我卖掉了我所有的宝石。除了一些，像RMagick，必须在本地编译。我的宝石规格都不正常。然后它会导致"git pull"部署失败。
现在我的生产应用程序甚至无法启动。当我尝试运行
时，最荒谬和无益的错误:rake gems:refresh_specs --trace
结果如下:
rake aborted!

是关于什么的?听起来好像在启动周期中有什么东西搞砸了，但在我看来一切正常。
我最终只是删除了所有的gem .specification文件:
从应用程序根目录:
find . -name ".specification" -exec rm -rf {} ;
:
rake gems:refresh_specs
。完成了!
