安裝cocoapods
在運行 “sudo gem install cocoapods” 的時候出現(xiàn)問題：ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/fuzzy_match
則可以改為：
sudo gem install -n /usr/local/bin cocoapods
安裝monkey

ERROR: Could not find a valid gem '/usr/bin' (>= 0) in any repository
ERROR: Possible alternatives: userbin
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.
解決：sudo gem install -n /usr/local/bin crash_monkey --no-ri --no-rdoc
