下载某个ios源码后，控制器进入目录执行pod install：
$ podinstallAnalyzing dependencies[!] TheversionofCocoaPods usedtogenerate the lockfile (0.39.0)ishigherthantheversionofthecurrentexecutable (0.35.0). Incompatibility issues may arise.
因此我们需要更新cocoapods，执行下面的命令，但是并没有更新成功。
$ gemupdatecocoapodUpdating installed gemsNothingtoupdate
查看当前版本：
$ pod--version0.35.0
怀疑source地址有变化：
$ gem sources -l*** CURRENT SOURCES ***http://ruby.taobao.org/
网上查看，告知taobao服务器已经改为https协议，因此执行如下：
$ gem sources -rhttp://ruby.taobao.org/http://ruby.taobao.org/ removed from sources$ gem sources -ahttps://ruby.taobao.org/https://ruby.taobao.org/ added to sources
更新系统，提示没有权限：
$ gemupdate--systemUpdating rubygems-updateFetching: rubygems-update-2.5.1.gem (100%)ERROR:Whileexecuting gem ... (Gem::FilePermissionError) You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
使用sudo来执行操作：
$ sudo gemupdate--systemUpdating rubygems-updateFetching:rubygems-update-2.5.1.gem (100%)Successfully installed rubygems-update-2.5.1Parsing documentationforrubygems-update-2.5.1
执行安装:
$ pod setupSettingupCocoaPods master repoSetup completed [!] CocoaPods was not abletoupdatethe `master` repo. If thisisanunexpected issueandpersists you can inspect it running `pod repoupdate--verbose`
根据提示执行repo更新:
$ pod repoupdate--verboseUpdating spec repo`master`$ /usr/bin/git pull--ff-onlyFromhttps://github.com/CocoaPods/Specs a0baa68..9a14a05master-> origin/mastererror: Yourlocalchangestothefollowingfiles would be overwrittenbymerge: CocoaPods-version.yml Specs/1PasswordExtension/1.0.0/1PasswordExtension.podspec.json Specs/1PasswordExtension/1.0.1/1PasswordExtension.podspec.json Specs/AKUTestKit/1.1.2/AKUTestKit.podspec.json Specs/ALCore Aborting Updating a5c6b67..9a14a05 [!] CocoaPods wasnotabletoupdatethe`master`repo.Ifthisisan unexpected issueandpersists you can inspect it running`pod repo update --verbose`
master分支还是失败，查看网上建议，先清除缓存
rm-rf ~/.cocoapods/repos/master
再重新运行：
$ pod setupSetting up CocoaPods master repo CocoaPods1.0.0.beta.2is available.To updateuse: `gem install cocoapods --pre`[!] This is a test version we'd love youtotry. For more information see http://blog.cocoapods.organdthe CHANGELOGforthis version http://git.io/BaH8pQ.Setup completed
最后，到下载的ios工程目录下，执行：
$ podinstallUpdatinglocalspecs repositories CocoaPods1.0.0.beta.2isavailable.Toupdateuse:`gem install cocoapods --pre`[!] Thisisatestversionwe'd love you to try.
