这两天在导入某些三方库时遇到问题在这里记录下，方便大家查看及检索报错如下
错误信息大概为 cocoapods Pods/Pods/Target Support Files/Pods-Video/Pods-Video.debug.xcconfig: unable to open file (in target "Video" in project "Video") (in target 'Video')
错误截图在网上找了好久才找到解决方案
解决方案：升级cocoapods 版本到1.6.1
执行命令：
sudo gem install cocoapods --pre或者sudo gem install -n /usr/local/bin cocoapods --pre
