ios - 无法通过CocoaPods安装GoogleMaps

Question

我想在我的项目中安装iOS版GoogleMap SDK。但是当我使用pod install安装时，出现了错误。

[!] Unable to find a specification for `GoogleMaps`

pod repo remove master ; pod setup没有帮助。 pod repo update --verbose

    Updating spec repo `.git`
  $ /usr/bin/git -C /Users/admin/.cocoapods/repos/.git fetch origin
  From https://github.com/CocoaPods/Specs
     42723a4..830f47f  master     -> origin/master
  $ /usr/bin/git -C /Users/admin/.cocoapods/repos/.git rev-parse --abbrev-ref
  HEAD
  HEAD
  $ /usr/bin/git -C /Users/admin/.cocoapods/repos/.git reset --hard origin/HEAD
  fatal: ambiguous argument 'origin/HEAD': unknown revision or path not in the working tree.
  Use '--' to separate paths from revisions, like this:
  'git <command> [<revision>...] -- [<file>...]'
[!] CocoaPods was not able to update the `.git` repo. If this is an unexpected issue and persists you can inspect it running `pod repo update --verbose`

我的Podfile:

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

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

  # Pods for Interests
    pod 'GoogleMaps'
  target 'InterestsTests' do
    inherit! :search_paths
    # Pods for testing
  end

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

end

您需要在Podfile的顶部指定Specs仓库，如下所示:
source 'https://github.com/CocoaPods/Specs.git'
由于您列出的错误，我可以看到这种情况:

Updating spec repo `.git`
[!] CocoaPods was not able to update the `.git` repo. If this is an unexpected issue and persists you can inspect it running `pod repo update --verbose`
