rake或任何其他rake命令无法正常工作

Question

嗨我正在做一些编码并试图

rake routes

并出现此错误消息,我不知道该怎么做

rake aborted!
Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 10.4.0. Prepending `bundle exec` to your command may solve this.

任何有关这方面的帮助将非常感激

Answer 1

运行命令后,我在旧项目中遇到此问题 rails new MyNewProject

为了在旧项目上修复它我刚进入Gemfile.lock文件并搜索rake.我发现rake (10.3.2)并替换了它rake (10.4.2)并为我修复了它.

Answer 2

您通常不应手动编辑gemfile.lock.如果您确实删除了该文件并从头开始重新启动,请确保gemfile指定了您的宝石版本,这样您就可以获得所期望的版本.对于这种情况:

$ bundle update rake

为我工作.

Answer 3

此错误是因为您的gem文件使用的是不同版本的rake,因此您需要指定所需的rake版本,这样可以帮助您

 bundle exec rake routes
