I'm trying to install the Devises gem, running bundle install and then getting this error with bcrypt-ruby which I haven't had before. What can I do?

Installing bcrypt-ruby (3.0.1) with native extensions

An error occured while installing bcrypt-ruby (3.0.1), and Bundler cannot continue.
Make sure that `gem install bcrypt-ruby -v '3.0.1'` succeeds before bundling.

Okay, so I need to install bcrypt-ruby...

要么你没有安装 XCode，要么你的开发者目录配置不正确。

如果是第一个，请尝试安装 XCode。

如果是第二个，试试这个（或一些变化，取决于你的 XCode 目录在哪里）

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

gem 'bcrypt-ruby', '~>3.0.1', :github => 'rking/bcrypt-ruby'

rking 的 bcrypt-ruby 分支注释掉 3.0.1 的失败 c 编译补丁。Bcrypt-ruby 在一年前修复了这个问题，但不是针对版本 3.0.1，这似乎是您的 Rails 应用程序所需的依赖项。
