Rails - 获取Rake错误

Question

运行rake命令时,我收到此错误:

You have already activated rake 10.0.2, but your Gemfile requires rake 11.1.1. 
Prepending `bundle exec` to your command may solve this.

如何解决这个问题,以便我不必bundle exec在每个rake命令之前运行？

我卸载了rake并重新安装,但它仍在寻找旧版本:

C:/Ruby22-x64/bin/rake:22:in `load': cannot load such file -- C:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/rake-10.4.2/bin/rake (LoadError)
        from C:/Ruby22-x64/bin/rake:22:in `<main>'

Answer 1

跑

$ bundle update rake

这对我有用.

看文档. http://bundler.io/v1.3/man/bundle-update.1.html

Answer 2

很简单：

gem install rake -v 11.1.1
