An error occurred 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.

然后我这样做

sudo gem install bcrypt-ruby -v '3.0.1'
Building native extensions.  This could take a while...

并得到一个错误。

我错过了什么?

有类似的问题:

通常,解决方案是:

sudo apt-get install ruby-dev

或者,如果这不起作用,根据您的 ruby​​ 版本 ,运行类似:

sudo apt-get install ruby1.9.1-dev

应该解决你的问题。


还是行不通?安装 ruby​​-dev 后尝试以下操作:

sudo apt-get install make
