ruby - 无法通过 rvm bundle install 安装 ffi 1.9.0 - OSX 10.8.4

Question

在带有自制软件、xcode(带有命令行工具)和 libffi 的 Macbook Pro 上使用 OSX 10.8.4。

我已经安装了 rvm 和 ruby​​-1.9.3-p448，并且有一个名为 omega.ecoop 的 gemset。有一个 gemfile 列出了该项目所需的 gem。但是，在运行 bundle check 后，我无法安装它们:

Bundler can't satisfy your Gemfile's dependencies.

这是正确的，因为它们没有安装。所以我使用:

bundle install

产生以下内容:

Installing ffi (1.9.0) 

一切顺利，直到:

An error occurred while installing ffi (1.9.0), and Bundler cannot continue.
Make sure that `gem install ffi -v '1.9.0'` succeeds before bundling.

这个命令也不起作用(gem install ffi -v '1.9.0')，我得到同样的错误。我试过:

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

我已阅读:

can't setup ruby environment - installing fii gem error

Bundle update fails on ffi

Bundle update fails on ffi

Error installing ffi

gem install ffi -v '1.1.5' osx 10.8

但仍然没有运气。我按照本指南设置了 RVM:

http://portertech.ca/2010/03/26/homebrew--rvm--awesome/

如果这有帮助，ffi-1.0.11 安装顺利，fff-1.9.0 将不会安装 ( http://rubygems.org/gems/ffi/versions)。

/Users/Sam/.rvm/gems/ruby-1.9.3-p448@omega.ecoop/gems/ffi-1.0.11 (no problem)

我只想使用命令行(而不是 jewelrybox GUI)来学习一些新技能，但相当卡在这里。任何帮助将不胜感激，谢谢。

编辑

所以我尝试了一种不同的方法，我认为可能是不兼容的 ruby​​ 版本:

rvm install 2.0.0

然后这次使用 ruby​​ 2.0.0 创建 gemset

rvm use 2.0.0@omega.ecoop --create

检查它在那里并选择为当前的 gemset(准备安装一些 gem)

rvm gemset list

gemsets for ruby-2.0.0-p247 (found in /Users/Sam/.rvm/gems/ruby-2.0.0-p247)
(default)
global
=> omega.ecoop

是的，一切都很好。尝试安装

bundle install

这次“安装 ffi (1.9.0)”没有问题。然后我删除了 ruby​​ 1.9.3，因为我目前只将它用于 compass/sass/susy，如果 2.0.0 可以工作，那就这样吧。

Sams-MacBook-Pro:~ Sam$ ruby -v
ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin12.3.0]
Sams-MacBook-Pro:~ Sam$ cd drupal/ecoop/sites/default/themes/ecoop/
ruby-1.9.3-p448 is not installed.

To install do: 'rvm install ruby-1.9.3-p448' <<<<<< no thanks

Sams-MacBook-Pro:ecoop Sam$ compass watch
>>> Change detected at 12:35:09 to: reset.scss

overwrite css/styles.css 
>>> Compass is watching for changes. Press Ctrl-C to Stop.

现在对我的项目来说效果很好。不确定使用更新版本的 ruby​​ 的任何后果，但已经浪费了足够的时间，需要做一些设计。显然，这不会帮助需要 1.9.3 的人，因此关于为什么 ffi 无法安装的原始查询尚未得到解决。

Answer 1

Sams-MacBook-Pro:~ Sam$ cd drupal/ecoop/sites/default/themes/ecoop/
ruby-1.9.3-p448 is not installed.

To install do: 'rvm install ruby-1.9.3-p448' <<<<<< no thanks

该目录中的 .ruby-version 文件仍然是 1.9.3。
