Question

我干净安装了Mac OS Yosemite，但现在Rails无法正常运行。

当我尝试rails s时，它会告诉我bundle install。

尝试运行bundle install后，我收到此消息：

Errno::EACCES: Permission denied - /Users/giowong/rails_project/doctible_pre_treatment/vendor/bundle/ruby/2.0.0/gems/bcrypt-3.1.7/.gitignore

我做了

sudo gem update --system

和

bundle install

当我这样做时，我会收到这些令人讨厌的东西：

 An error occurred while installing bcrypt (3.1.7), and Bundler cannot continue.
 Make sure that `gem install bcrypt -v '3.1.7'` succeeds before bundling.

我尝试使用

进行安装

 \curl -sSL https://get.rvm.io | bash -s stable --rails

但没有运气。

我不建议使用随OS X提供的默认Ruby，因此请安装RVM。您还需要安装Xcode命令行工具：

xcode-select --install # click install, not Get Xcode

然后验证是否安装了gcc：

gcc --version

然后才开始运行：

\curl -sSL https://get.rvm.io | bash -s stable --rails

发布OS X 10.10 Yosemite安装Rails错误
