你试过gem update --system吗?您可能需要更新版本的rubygems。

如果您使用rvm使用以下设置默认的ruby版本,那么它将拾取正确的ruby版本。你可能需要在设置默认值

后运行bundle install / gem install rails -v 4.2.5
rvm --default 2.2.2

好的,我在遇到与海报相同的问题后遇到了这个问题。他的更新建议从Gemfile中删除spring帮助我走上了正确的轨道。对我来说,问题是我引入了一个新的环境变量,但spring并没有采用。当您从Gemfile中删除spring时,它会阻止您的应用使用spring进程,但并没有真正停止spring进程,因此将其重新添加,进行捆绑安装或其他操作仍然会给您带来麻烦。春季进程正在运行。

要查看这是否可能是您的问题,可以检查bin/spring status并查看spring是否在后台运行以及是否已经运行了一段时间。

解决方案(至少对我来说):重新启动spring

bin/spring stop
rails c
