Mac上RoR环境搭建问题

昨天一晚上折磨的我啊都快疯掉了。

按照http://railstutorial-china.org方法配制,到rvm requirements这个命令执行时就麻烦事来了。

WutekiMacBook-Pro:~ wuxj$ rvm requirements
Checking requirements for osx.
Error: No available formula for gcc46 
Installing requirements for osx.
Updating system.......

Requirements installation failed with status: 1.

开始以为是Homebrew没更新,所以执行了下brew update,结果:

WutekiMacBook-Pro:~ wuxj$ brew update
error: The following untracked working tree files would be overwritten by merge:
    Library/Formula/ant.rb
    Library/Formula/libarchive.rb
Please move or remove them before you can merge.
Aborting
Error: Failure while executing: git pull -q origin refs/heads/master:refs/remotes/origin/master

执行了下brew doctor

WutekiMacBook-Pro:~ wuxj$ brew doctor
Warning: Some directories in your path end in a slash.
Directories in your path should not end in a slash. This can break other
doctor checks. The following directories should be edited:
    /Users/wuxj/Downloads/adt-bundle-mac-x86_64-20131030/sdk/platform-tools/
Error: Homebrew doesn‘t know what compiler versions ship with your version
of Xcode (5.1.1). Please `brew update` and if that doesn‘t help, file
an issue with the output of `brew --config`:

Thanks!

执行bundle

An error occurred while installing nokogiri (1.6.3.1), and Bundler cannot continue.
Make sure that `gem install nokogiri -v ‘1.6.3.1‘` succeeds before bundling.

依然不行,执行 gem install nokogiri -v ‘1.6.3.1‘ , 还是不行。

最后,在stackoverflow上找到个大神解救了我。就是各种brew安装啊。。。

brew install autoconf
brew install automake
brew install libtool
brew install ap
ple-gcc42 brew install libyaml brew install libxslt brew install libksba brew install openssl

结果

WutekiMacBook-Pro:sample_app wuxj$ rvm requirements
Checking requirements for osx.
Updating certificates in ‘/usr/local/etc/openssl/cert.pem‘.
Requirements installation successful.

终于解决了。
