在ffi上捆绑更新失败
我正在尝试在我的rails应用程序上进行bundle update ，但是我收到以下错误：

有任何想法吗？
昨天我遇到了类似的问题。
我能够使用以下步骤解决它：
https://github.com/carlhuda/bundler/blob/1-0-stable/ISSUES.md
从本质上讲，我的捆绑包存在问题并清除了问题并从头开始重建事情解决了问题。
这里重复这些步骤：
# remove user-specific gems and git repos rm -rf ~/.bundle/ ~/.gem/ # remove system-wide git repos and git checkouts rm -rf $GEM_HOME/bundler/ $GEM_HOME/cache/bundler/ # remove project-specific settings and git repos rm -rf .bundle/ # remove project-specific cached .gem files rm -rf vendor/cache/ # remove the saved resolve of the Gemfile rm -rf Gemfile.lock # try to install one more time bundle install
虽然，在输出文本中给出了消息：
您必须首先安装开发工具。
这让我觉得你可能没有安装Apple Xcode开发者工具 。 你检查过了吗？ （我相信它们可以在Mac App Store中找到。）
对于Xcode 5及更高版本：
$ xcode-select --install
安装命令行工具。
从brew安装gcc-4.2后，您需要创建它的符号链接：
ln -s /usr/bin/gcc /usr/bin/gcc-4.2
以防万一尝试运行
sudo / usr / bin / gcc
你可能会看到许可协议，所以滚动它，输入“同意”并尝试再次安装gem。
请注意：
如果您最近更新了Xcode，则可能只需要打开Xcode并接受最新协议 。
我有同样的问题，最近安装了Xcode（v6.1）的更新，并通过以下步骤解决了它：
- 打开Xcode
- 接受新协议
- 重新运行捆绑包更新
通过Xcode安装“命令行工具”就可以了。
如果您有Xcode 4.5，请打开首选项 > 下载 >选择组件选项卡，然后单击命令行工具旁边的安装 。
虽然我是从Xcode安装的，但您也可以从Apple的Developer Downloads下载没有它的软件包并搜索“命令行工具” 。
对我来说，我只是没有安装gcc，在Ubuntu解决：
sudo apt install build-essential
我不得不接受Xcode用户许可证：
运行sudo xcrun cc应该会显示Xcode许可协议的cli版本。 另一个选择是打开Xcode.app并在GUI中同意。
可能是由更新OSX引起的。

Mac OSx 10.10.2优胜美地
CC=/usr/bin/i686-apple-darwin11-llvm-gcc-4.2 gem install ffi
这就是它 – 检查你可以挂钩的/usr/bin中有4.2编译器
ls /usr/bin|grep gcc|grep 4.2
您不必擦除所有本地gem或覆盖符号链接来执行此操作 – 这是浪费时间并且可能会产生更多问题然后解决。
请注意，如果您需要通过brew安装，您的bin路径可能会有所不同
brew install apple-gcc42
还方法：
export SDKROOT=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk bundle update
ffi.h可以在${SDKROOT}/usr/include/ffi/ffi.h 。
Ubuntu Trusty LTS 14.04
需要从ruby 2.2.1切换到2.3.0以支持Rails应用程序中的新gem版本。
解：
-
rvm get stable -
rvm remove 2.3.0 -
rvm install 2.3.0 -
bundle install
