我是编程的新手,我正试图在我的终端上安装rails.我一直在按照朋友的指示,安装xcode命令行工具,自制程序,git,rbenv,ruby-build,ruby gems,ruby和postgres.但无论何时,我尝试$ gem install rails,我得到以下内容:
Russell-Silvers-MacBook-Pro:~ Russell_Silver$ gem install rails

Permission denied @ rb_sysopen - /Users/Russell_Silver/.rbenv/versions/2.1.5/lib/ruby/gems/2.1.0/gems/rails-4.2.0/README.md
这尤其令人沮丧,因为当我运行$ gem list时,它说我有rails 3.2.18.这是特殊的,因为当我运行$ rails v $时,它告诉我我有Rails 4.2.0.
当我尝试使用rails时 rails my new_app
