rake aborted!
Gem::LoadError: You have already activated rake 10.3.2, but your Gemfile requires rake 10.2.2. Prepending `bundle exec` to your command may solve this.

Answer 1

尝试运行bundle exec rake routes以确保正确版本的Rake被加载。

Answer 2

您需要将gem更新为最新的可用版本： bundle update

Answer 3

Rake versions seems to be different. So, run it as bundle exec rake routes . It should be working.

Answer 4

The correct solution to your problem is to use bundle exec , as suggested by others, to load the version of Rake which your app expects. You may also wish to avoid needing to always run Rake commands with bundle exec . You can either

1) [Recommended] Update your app to use the same version of rake as you have running globally (10.3.2, which is the latest version)

or

2) [Not really recommended] Uninstall version 10.3.2 (actually, any version greater than the one you want) from your global gems and install version 10.2.2 (which your app is currently using)

rvm @global do gem uninstall rake
rvm @global do gem install rake --version 10.2.2

See RVM documentation for global gemsets
