title: Error running pod install: `UMFileSystemInterface` depended upon by `EXAV`
body: <p>I am developing mobile app for Android and ios using React Native. I developed app on Windows machine and run it successfully. I have a lot of modules and everything works well on Android.</p>
  <p>Now, I am trying to install all modules on macOS. I run <code>npm install</code> and then tried to run <code>npx pod-install</code> but got this error:
  <code>[!] Unable to find a specification for UMFileSystemInterface depended upon by EXAV</code>.</p>
  <p>I thought that this problem might be because of <code>react-native-unimodules</code> and I followed documentation on how to install this module on ios, but that didn't help. Any idea how to solve this problem?</p>
  <p>Here is my Podfile</p>
  <pre><code>require_relative '../node_modules/react-native-unimodules/cocoapods.rb'
  
  require File.join(`node --print &quot;require.resolve('react-native/package.json')&quot;`, &quot;../scripts/react_native_pods&quot;)
  require File.join(`node --print &quot;require.resolve('@react-native-community/cli-platform-ios/package.json')&quot;`, &quot;../native_modules&quot;)
  require File.join(`node --print &quot;require.resolve('react-native-unimodules/package.json')&quot;`, &quot;../cocoapods&quot;)

      config = use_native_modules!
  
    use_react_native!(:path =&gt; config[&quot;reactNativePath&quot;])
  
    # Uncomment to opt-in to using Flipper
    #
    # if !ENV['CI']
    #   use_flipper!('Flipper' =&gt; '0.75.1', 'Flipper-Folly' =&gt; '2.5.3', 'Flipper-RSocket' =&gt; '1.3.1')
    #   post_install do |installer|
    #     flipper_post_install(installer)
    #   end
    # end
  end
