# pod installで引っかかる

## ドキュメント内のライブラリ一覧のURLが404

ドキュメントに始め方が書いてあり、podで入れればいいと書いてありますが、

```rb
platform :ios, '8.0'
swift_version = '4.1'

target 'MyApp' do

  pod 'RSocket', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/iOS/third-party-podspecs/RSocket.podspec?token=ADr9NE_I05Vu8g7oq_g6g_9FLx784NFmks5bJ5LvwA%3D%3D'
  pod 'DoubleConversion', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/iOS/third-party-podspecs/DoubleConversion.podspec?token=ADr9NOxtIEmr5ODP9PWq6-sht-Ye6UYGks5bJ5MjwA%3D%3D'
  pod 'glog', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/iOS/third-party-podspecs/glog.podspec?token=ADr9NBHbrlbkFR3DQTPzj0CnZdria4jvks5bJ5M3wA%3D%3D'

  pod 'PeerTalk', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/iOS/third-party-podspecs/PeerTalk.podspec?token=ADr9NB8frQTrUWytsMXtdv_P8km7jV_Mks5bJ5NbwA%3D%3D'
  pod 'Yoga','~>1.8.1', :modular_headers => true
  pod 'Sonar', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/xplat/Sonar/Sonar.podspec?token=ADr9NFO7byH9uAuhGAIEYuoJeBNyBxf6ks5bJ5N8wA%3D%3D'
  pod 'SonarKit', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/SonarKit.podspec?token=ADr9NBuYoodM_NeysQg899hkxXw0WZ7Xks5bJ5OVwA%3D%3D'
  pod 'SonarKit/SonarKitLayoutComponentKitSupport', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/SonarKit.podspec?token=ADr9NBuYoodM_NeysQg899hkxXw0WZ7Xks5bJ5OVwA%3D%3D'

  pod 'ComponentKit', :podspec => 'https://raw.githubusercontent.com/facebook/Sonar/master/iOS/third-party-podspecs/ComponentKit.podspec?token=ADr9NNV9gqkpFTUKaHpCiYOZIG3Ev-Hyks5bJ5O-wA%3D%3D'
  post_install do |installer|
        installer.pods_project.targets.each do |target|
            if ['YogaKit'].include? target.name
                target.build_configurations.each do |config|
                    config.build_settings['SWIFT_VERSION'] = swift_version
                end
            end
        end
    end
end
```

`SonarKit`と`SonarKit/SonarKitLayoutComponentKitSupport`と`SonarKit/SKIOSNetworkPlugin`がこのような404のエラーを吐きます

```

            if ['YogaKit'].include? target.name
                target.build_configurations.each do |config|
                    config.build_settings['SWIFT_VERSION'] = swift_version
                end
            end
        end
    end

end
```

## 自分の入れてたCocoaPodsのバージョンが低くて引っかかる
`CocoaPods`バージョン1.2.0をいれていました

このようなエラーが出ていました

```
$ bundle exec pod install
[!] A dependency with an external source may not specify version requirements (Yoga).
```

podfileを編集してYoga以外をいれようとすると下記のようなエラーが出てきました

```
$ bundle exec pod install
[!] Invalid `SonarKit.podspec` file: undefined method `static_framework=' for #<Pod::Specification name="SonarKit">
Did you mean?  weak_framework=.

 #  from SonarKit.podspec:12
 #  -------------------------------------------
 #    spec.authors = 'Facebook'
 >    spec.static_framework = true
 #    spec.source = { :git => 'https://github.com/facebook/Sonar.git',
 #  -------------------------------------------
```

`CocoaPods`バージョンを最新の1.5.2にあげると無事にワークスペースが作られました
