rbenv Your user account isn't allowed to install to the system Rubygems

 

Clone一个新Rails项目到Mac， bundle install 的时候遇到下面的提示

 

Fetching source index from http://rubygems.org/ Your user account isn't allowed to install to the system Rubygems.

也就是说，rbenv 要往你系统的自带Ruby里面安装gem.

gem list | grep bundler

用上面的命令看看你是否经过rbenv安装了bundler. 若是没有那就对了，因此只能去找系统的ruby了，那么你可能不但愿这样。

因此解决办法已经明了：

gem install bundler
rbenv rehash
