iOS GCM 示例的无效 Podfile

Question

我正在尝试按照 Google 开发人员页面上的说明安装 GCM 示例 Xcode 项目 https://developers.google.com/cloud-messaging/ios/start

但在第 1 步失败并显示此消息：

[!] Invalid `Podfile` file: [!] The specification of `link_with` in the Podfile is now unsupported, please use target blocks instead..

完整的成绩单是这样的：

$ pod try Google --no-repo-update

Trying Google
1: Samples/admob/AdMobExample.xcodeproj
2: Samples/analytics/AnalyticsExample.xcodeproj
3: Samples/appinvites/AppInvitesExample.xcodeproj
4: Samples/gcm/GcmExample.xcodeproj
5: Samples/signin/SignInExample.xcodeproj

Performing CocoaPods Installation

[!] Invalid `Podfile` file: [!] The specification of `link_with` in the Podfile is now unsupported, please use target blocks instead..

 #  from /private/var/folders/d5/f4qpz1r530xbw5cyrbfk094h0000gp/T/CocoaPods/Try/Google/Samples/gcm/Podfile:10
 #  -------------------------------------------
 #  # and delete the link_with command.
 >  link_with 'GcmExample', 'GcmExampleSwift'
 #  ------------------------------------------

我已尝试按照错误消息中的建议修改 podfile，但即使使用 --no-repo-update option 运行并产生相同的错误，也会重新生成 Podfile。

我之前没有使用 Pod 的经验，因此欢迎提出任何建议。

转到路径：“/private/var/folders/lx/78jh00l90p95cs1cy_545t2r0000gn/T/CocoaPods/Try/Google/Samples/gcm”然后只需打开 pod 文件并将其更新为

# GcmExample
 target 'GcmExample' do
  platform :ios, '7.0'
   pod 'Google/CloudMessaging'
end
# If using CocoaPods 1.0.0+, use the new target syntax.
#target 'GcmExample'
#target 'GcmExampleSwift'

# and delete the link_with command.
#link_with 'GcmExample', 'GcmExampleSwift'

然后，pod 安装
