title: pod install failed with error: Library (from `../`)` required by `Podfile` when pod install in iOS
body: <p>I am making a cocoapods. I am using <code>pod lib create MyLibrary</code> to create a new cocoapods. After it's done, I added two files into MyLibrary/Pod/Classes/. And I commit and add a tag and then push to origin master. and the MyLibrary.podspec passed validation. So, I go into the Example folder which created when I do <code>pod lib create MyLibrary</code>. and do a <code>pod install</code> in the terminal. But I am getting error:</p>
  
  <pre><code>Analyzing dependencies
  Fetching podspec for `MyLibrary` from `../`
  [!] Unable to satisfy the following requirements:
  
  - `MyLibrary (from `../`)` required by `Podfile`
  </code></pre>
  
  <p>The podspec settings are all correct, like this one <code>s.source_files = 'Pod/Classes/*.{h,m}'</code>, and it passed the validation. So I think there is no problem with pod spec file. It seems the pod installation can't find the Pod folder. But it is right there. </p>
  
  <p>I am new to this making cocoapods. So if there is anything that not clear, please let me know. I don't know what I am doing wrong here.</p>
