安裝Ruby on Rails：-bash：bundle：命令未找到

Question

在我的應用程序中運行捆綁軟件時出現問題，我復制了命令和日志，並顯示在下面。

$ 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，在看到該錯誤之后，我運行了以下命令：

$ gem install rake -v 10.4.2

$ bundle exec rake db:setup

-bash: bundle: command not found

如何修復可以在rake db:setup運行的錯誤？

您需要安裝bundler ，然后可以使用bundle命令。

gem install bundler

試試這個命令bundle exec

bundle exec rake db:setup
