按照上图红线标注信息进行查找修改，以我的错误信息为例：

如下图，在MyStudySwiftTests的build setting中查找ALWAYS_EMBED_SWIFT_STANDARD_LIBRARIES，选择other添加$(inherited)，编译，重新pod install解决错误

2、mac系统更新导致cocoapods失效

解决办法：

$ sudo gem update --system
$ sudo gem install cocoapods -n/usr/local/bin

3、cocoapods搜索不到最新的三方库

4、cocoapods安装时提示吐下信息

Automatically assigning platform ios with version 9.0 on target XiaoFeiShang_Swift because no platform was specified. Please specify a platform for this target in your Podfile. See https://guides.cocoapods.org/syntax/podfile.html#platform.
解决办法：去掉Podfile中platform前的#符号

# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'

target 'XiaoFeiShang_Swift' do
  # Comment the next line if you're not using Swift and don't want to use dynamic frameworks
  use_frameworks!

  # Pods for XiaoFeiShang_Swift

end

5、cocoapods搜索不到三方库最新版本

pod cache clean --all
rm -rf ~/Library/Caches/CocoaPods
pod repo update

6、执行pod install时报错

错误信息

错误原因：如上图所示，需要安装的三方库为Alamofire，版本为5.0.0-beta.2，该版本最低支持的iOS target为10.0，但我的podfile文件中platform版本是低于10.0的，所以报错
修改方法：如下图所示，将platform后版本修改为10.0即可

修改信息

7、错误信息如下：

cocoapods Pods/Pods/Target Support Files/Pods-xxx/Pods-xxx.debug.xcconfig: unable to open file (in target "xxx" in project "xxx") (in target 'xxx')
解决办法一：

sudo gem install cocoapods --pre   

如果执行失败，提示You don't have write permissions for the /usr/bin directory，使用方法二：

sudo gem install cocoapods -n/usr/local/bin --pre
