在项目中由于需要用到ffmpeg来完成视频直播，用到百度云的sdk，需要下载openssl，但是每次pod install都报如下的错误

产生的原因应该是cocoapods-downloader 版本的问题，使用命令 gem list --local | grep cocoapods 可以查看cocoapods-downloader的版本，在高于1.2.0的版本会报该错误
解决方法
打开终端，输入如下命令.
sudo gem uninstall cocoapods-downloader
sudo gem install cocoapods-downloader -v 1.2.0
rm -r ${TMPDIR}/openssl/
最后pod install即可。
