"bundle-install“失败

Question

我正试图在Ubuntu上做一个新的项目。克隆GitHub回购并安装ruby sudo apt-get install ruby之后，y执行

bundle install

我得到的反馈是：

Make sure that `gem install ffi -v '1.8.1'` succeeds before bundling.

我遗漏了什么？

Answer 1

试试sudo apt-get install ruby1.9-dev。

然后又是bundle install。

顺便说一句，您可能不想弄乱系统红宝石，而是在本地安装ruby，而使用里本夫或rvm。
