通过RVM安装Ruby失败

第一次安装失败是由于Homebrew一直安装不成功，遂去http://brew.sh/index_zh-cn.html官网

通过

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

复制到终端中直接安装，安装成功后再通过RVM安装Ruby还是失败，根据提示输入brew doctor查找原因，发现时Xcode版本过低，更新安装之后并运行Xcode，再通过

rvm install 2.3.0

安装了Ruby，安装Ruby成功后输入按照常规步骤到

pod repo remove master出现如下错误

[!] repo master does not exist

尝试更换源，输入如下

pod repo add master http://git.oschina.net/akuandev/Specs.git出现如下错误

[!] To setup the master specs repo, please run `pod setup`.

切换源失败，根据提示输入pod setup

刚开始尝试很多次，都是如下错误

Setting up CocoaPods master repo

[!] /usr/local/bin/git clone https://github.com/CocoaPods/Specs.git master

Cloning into 'master'...

error: RPC failed; curl 56 SSLRead() return error -9806

fatal: The remote end hung up unexpectedly

fatal: early EOF

fatal: index-pack failed

通过网络查询很久后死马当活马医，很多人遇到

error: RPC failed; curl 56 SSLRead() return error -36

输入

sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer就能pop setup成功

遂在终端输入如上

再进行pod setup，结果如下

Setting up CocoaPods master repo

CocoaPods 1.1.0.rc.2 is available.

To update use: `sudo gem install cocoapods --pre`

[!] This is a test version we'd love you to try.

For more information, see https://blog.cocoapods.org and the CHANGELOG for this version at https://github.com/CocoaPods/CocoaPods/releases/tag/1.1.0.rc.2

Setup completed 有了绿色的Setup completed即可

最后成功安装好Ruby

注：确保安装了Xcode命令行工具，忘记是在哪一步安装了此工具，在终端输入

xcode-select --install  即可安装，
