Cocoapods Firebase吊舱更新

Question

早上好，我在更新Firebase / Analytics和Firebase / Core吊舱时遇到问题。

我的Podfile：

source 'https://github.com/CocoaPods/Specs.git'
source 'https://github.com/CocoaPods/Specs'
platform :ios, '10.0'

target 'Unity-iPhone' do
pod 'Firebase/Analytics', '5.15.0'
pod 'Firebase/Core', '5.15.0'
pod 'Firebase/Messaging', '5.1.0'
pod 'GoogleAppMeasurement', '5.3.0'
pod 'Google-Mobile-Ads-SDK', '~> 7.0'
end

如果我运行pod install，我将得到以下输出

Analyzing dependencies

[!] CocoaPods could not find compatible versions for pod "Firebase/Analytics":
  In Podfile:
    Firebase/Analytics (= 5.15.0)

None of your spec sources contain a spec satisfying the dependency: `Firebase/Analytics (= 5.15.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.

与pod outdated：

所以我运行pod update：

但是“ Firebase / Analytics”仍在5.1.0版上 我哪里错了？我已经尝试过多次安装repo master了，还有gem

如消息所示，您应该先执行pod repo update，然后再执行pod update。希望这会有所帮助。
