编译器无法生成可执行文件。 （RuntimeError）
我最近升级到OS Mountain Lion。 我正在处理的项目需要gem sys-proctable作为依赖项，但是当我运行bundle install我得到：

Make sure that `gem install sys-proctable -v '0.9.2'` succeeds before bundling.
但我确实安装了开发人员工具！ 运行gem install sys-proctable -v '0.9.2'给出了几乎相同的错误：

这是我的mkmf.log文件的内容：

发生同样的问题，我终于解决了。 以下是我遵循的步骤：
- Xcode，Xcode CLT
-
sudo xcodebuild -license -
sudo port upgrade outdated -
sudo port install apple-gcc42 -
rvm reinstall 1.9.3#important！
真的，我认为只需要第一步，第二步和最后一步，但无法测试它。
确保在更新后打开XCode。 我发现在最近通过App Store更新XCode后，我必须打开它并接受新的许可协议。 否则我收到“编译器无法生成可执行文件。（RuntimeError）您必须先安装开发工具。”
如果您使用的是rbenv和自制软件：
brew tap homebrew/dupes ; brew install apple-gcc42
以下步骤解决了该问题。
- xcode-select安装
- sudo xcodebuild -license
希望它可以帮到某人。
事实certificate这是RailsInstaller OSX 1.0.3中的一个错误 – （在阅读在Mountain Lion上安装Ruby时遇到的问题 – ruby1.9.3不会’编译 ）
我需要更改/etc/rvmrc来包含这个：

我在“捆绑安装”期间收到以下错误：
Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension. /Users/bob/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb creating Makefile make compiling generator.c make: /usr/bin/gcc-4.2: No such file or directory make: *** [generator.o] Error 1 Gem files will remain installed in /Users/bob/.rvm/gems/ruby-1.9.3-p194@storefront/gems/json-1.8.0 for inspection.

Make sure that `gem install json -v '1.8.0'` succeeds before bundling.
更新Xcode并安装CLT后，执行以下操作可以解决此问题：
bundle clean --force bundle install
因为我相信我会再次降落在这里。
我的问题是， sudo xcodebuild -license实际上什么都不做，我不得不手动启动xcode以同意他们的条款才能使它工作。 多么光荣的操作系统。
当我在Mountain Lion上遇到相同的问题时，我无法重复多少让我感到沮丧。 在我读到Mountain Lion存在一些GCC问题后，我最终将操作系统升级为Mavericks。 我仍然有同样的错误：/
唯一有用的是在安装命令行工具后重新安装ruby。
“对于未来的访问者来说，这对我有用。不是说它应该重要但是我安装了rvm和brew。已经安装了Xcode和Xcode CLT。我只需要（在任何一个都没有sudo）rvm使用2.0.0，然后xcode -license，同意许可证然后rvm重新安装2.0.0。最后一步非常重要，确实“
然后$ gem安装rails
这完全解决了我的问题。 这个博客提供了一个很棒的演练，其中有关于如何以多种方式安装Mac开发工具（命令行工具）的截图（ http://www.moncefbelyamani.com/how-to-install-xcode-homebrew-git-rvm-ruby-on -mac / ）
您必须安装最新的Xcode和命令行工具（在Xcode内）。 这显然与你的Xcode或PATH有关。 which clang给了什么？
