Gabriellas-MBP:~ GabriellaKampe$ gem install rails
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
Gabriellas-MBP:~ GabriellaKampe$  sudo gem install rails

Answer 1

您无权写入与操作系统捆绑在一起的ruby版本的gemfile目录。您需要做的是使用rbenv或rvm管理您的ruby版本。我会推荐rbenv，您可以按照这些链接rbenv rails install Mac OS或rbenv rails install Ubuntu
