bcrypt-ruby宝石宝石：：Installer：：ExtensionBuildError：

Question

日安。我正在尝试建立一个由其他人负责的项目。

当我运行bundle install时，它会因错误而崩溃

sudo创业板安装bcrypt -v '3.0.1'

$ sudo gem install bcrypt-ruby -v '3.0.1'

看起来没有安装ruby开发库。

看起来您还在使用全局ruby/gems安装，所以最简单的修复方法是安装ruby1.9-dev包(或类似的程序包)，然后再试一次。

或者，您可以使用rvm，此问题将自行修复：https://rvm.io/
