使用cocapods导入百度SDK的时候，抛出了如下异常：

解决办法：
在终端运行如下语句
sudo gem install cocoapods运行该语句后，如果出现以下情况，证明执行成功：
Parsing documentation for cocoapods-1.5.3
Done installing documentation for cocoapods after 2 seconds
1 gem installed此时载执行下载操作即可:
pod install运行该语句后，如果出现以下情况，证明执行失败：
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory.此时需要我们在执行另一步操作：
sudo gem install -n /usr/local/bin cocoapods执行该命令后，出现以下提示，证明操作成功：
Parsing documentation for cocoapods-1.5.3
