iOS开发之--cocopods相关问题及解决方法

问题一、

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default

解决办法:删除工程中的Podfile.lock,再pod intall.

 问题二、

[!] CocoaPods could not find compatible versions for pod "IQKeyboardManager":
  In snapshot (Podfile.lock):
    IQKeyboardManager (= 6.3.2)
 
  In Podfile:
    IQKeyboardManager (~> 6.3.2)
 
None of your spec sources contain a spec satisfying the dependencies: `IQKeyboardManager (~> 4.0.11), IQKeyboardManager (= 4.0.11)`.
 
You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.
 
Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

解决方法如下：

// 移除本地master
sudo rm -fr ~/.cocoapods/repos/master
// 移除本地缓存
sudo rm -fr ~/Library/Caches/CocoaPods/
// 重新setup,如果网速较慢,可以在后面加上 --verbose
pod setup

// 更新到最新的预览版,一次到底
sudo gem install cocoapods --pre

如果sudo gem install cocoapods --pre 
无效才考虑移除本地缓存
