An error occurred while installing ffi (1.9.2), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.9.2'` succeeds before bundling.

这是我执行 bundle 更新时的错误，所以我按照上面最后一行的建议执行了以下操作

    $ gem install ffi -v '1.9.2'
    Building native extensions.  This could take a while...
    ERROR:  Error installing ffi:

            c:/jruby-1.7.4/bin/jruby.exe extconf.rb

    make

然后我尝试了以下

$ gem install ffi

Answer 1

'make' is not recognized as an internal or external command, operable program or batch file.

看起来像 Windows 错误消息..您的系统上是否安装了 make？我会查看 Cygwin以避免在 unix 工具上出现依赖性问题。
