无法找到“Google地方信息”的规范

Question

我正在尝试将Google Places SDK添加到我的xcode项目中，但不断收到错误

Unable to find a specification for `GooglePlacePicker`

这是我的pod文件

# Uncomment the next line to define a global platform for your project
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '9.0'

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

  # Pods for Restaurant
 pod 'GooglePlaces'
 pod 'GooglePlacePicker'
 pod 'GoogleMaps'


  target 'RestaurantTests' do
    inherit! :search_paths
    # Pods for testing


  end

  target 'RestaurantUITests' do
    inherit! :search_paths
    # Pods for testing
  end

end

有趣的是，如果我删除'GooglePlaces'和'GooglePlacePicker'，它就会完全安装'GoogleMaps'。
