Question

在我的应用程序中运行bundle时出现问题，我已经复制了命令和日志，并在下面显示。

$ cd ~/Desktop/chinook/

$ rake db:setup

rake aborted!
Gem::LoadError: You have already activated rake 11.1.2, but your Gemfile requires rake 10.4.2. Prepending `bundle exec` to your command may solve this.

然后在看到错误后我运行了这个命令：

$ gem install rake -v 10.4.2

$ bundle exec rake db:setup

-bash: bundle: command not found

如何修复此错误，我可以运行rake db:setup？

bundle exec rake db:setup
