在新的Mac Mini上安裝Xcode和pods。
結果這個Mac配置不好，慢的離譜，讓人上火。
好不容易Xcode安裝完成了。
新建項目要用到pods。
那么又要安裝了。
打開終端。
先安裝rvm。
$ rvm install 2.2.2
然后裝的令人上火，大概用了N久N久N久，我一惱，被我關掉了。很尷尬。
于是再次打開重新安裝。于是出問題了。
Installing required packages: openssl....
Error running 'requirements_osx_brew_libs_install openssl',
showing last 15 lines of /Users/mac-mini/.rvm/log/1471423170/package_install_openssl.log
+ case "$1" in
+ [[ -t 1 ]]
+ return 1
+ printf %b 'There were package installation errors, make sure to read the log.
Try `brew tap --repair` and make sure `brew doctor` looks reasonable.
Check Homebrew requirements https://github.com/Homebrew/homebrew/wiki/Installation\n'
There were package installation errors, make sure to read the log.
Try `brew tap --repair` and make sure `brew doctor` looks reasonable.
Check Homebrew requirements https://github.com/Homebrew/homebrew/wiki/Installation
+ case "$_system_version" in
+ return 1
Requirements installation failed with status: 1.
然后很尷尬的，沒辦法安裝下去了，這時候看到了這個
Error running 'requirements_osx_brew_libs_install openssl',
那么就google一下咯。
結果找到方法了。
在終端上打上這句話
$ sudo chown -R "$USER" "$HOME"
等待執行。。。。。
然后出現了
chown:/User/mac-mini/Library/Caches/Cornerstone/...............
后面太長了，懶得打了。之后再重新試一下。
$ rvm requirements
執行之后發現可喜可賀的可以安裝了。
Checking requirements for osx.
Installing requirements for osx.
Updating system.....
Installing required packages: readline, openssl.....
Certificates in '/usr/local/etc/openssl/cert.pem' are already up to date.
Requirements installation successful.
于是此時執行
$ rvm install 2.2.2
然后就終于可以安裝了！
之后就可以執行
$ sudo gem install cocoapods
安裝pods啦！
非常完美～ : )
