“db：migrate rake”抛出错误“无法加载此类文件 - bundler / setup”

Question

我是rails初学者的红宝石，我试图在我的本地mac上运行rails应用程序。我已经设置了环境和MySQL数据库，直到最后一个设置步骤：db:migrate rake，它才是完整的。我收到以下错误：

cannot load such file -- bundler/setup
/Users/snailwalker/vietnam/snailwalker/config/boot.rb:7:in `<top (required)>'
/Users/snailwalker/vietnam/snailwalker/config/application.rb:2:in `<top (required)>'
/Users/snailwalker/vietnam/snailwalker/Rakefile:5:in `<top (required)>'

我错过了什么？

Answer 1

  

无法加载此类文件 - bundler / setup

此问题的原因很可能是您没有bundler。您应该安装bundler然后尝试再次运行迁移。

gem install bundler
bundle install
bundle exec rake db:migrate

希望它会帮助你。
