Completely nothing worked out for me from these answers. Had to create the project again by running cordova platform add ios. What I've noticed, even freshly generated project with (in my case) Firebase pods caused the error message over and over again. In my opinion looks like a bug for some (Firebase, RestKit) pods in Xcode or CocoaPods. To have the pods included I could simply edit my config.xml and run cordova platform add iOS, which did everything for me automatically. Not sure if it will work in all scenarios though.

编辑:我有一个Podfile从以前的iOS/Xcode，但最新的今天有# DO NOT MODIFY -自动生成的Apache Cordova在Podfile。这让我的脑海中亮起了一盏灯，开始尝试这种方法。看起来有点琐碎，但很管用，我的Firebase功能也很管用。

在我的案例中，我在集成WatchKit应用程序后得到了同样的错误。为了解决问题，我需要在Podfile中添加WatchKit的两个目标:

target 'MyProject WatchKit App' do
    platform :watchos, '2.0'
    shared_pods
end

target 'MyProject WatchKit App Extension' do
    platform :watchos, '2.0'
    shared_pods
end

PS:也许这发生在我身上，因为我错误地为MyProject WatchKit应用程序目标最初安装了pods。

我找到了我的解决方案:运行:pod update而不是pod install。错误被修正了!

你能试试这个吗:

删除Pods文件夹 删除Podfile.lock 运行pod安装 清洁+建造

当你这样做时

pod install --verbose

确保:

1-您在正确的目录。大多数情况下，当下载一个github项目时，会有一个主文件夹。在调用pod install——verbose之前，您需要在终端中的实际项目名称文件夹(masterfolder/project folder)中

2-删除旧的pod锁文件夹，然后使用xcode clean & do pod install清理项目。

3-保持rvm更新。
