我的问题是可可豆荚版本，所以我安装了最新的: Sudo gem安装cocoapods—pre 然后pod更新

这对我很有用

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。

我也有同样的问题 我将所有内容更新到最新 来自: NPM -v 6.4.1 节点-v v10.2.1 Pod——1.5.3版

: NPM -v 6.5.0 Node -v v11.8.0 Pod——1.6.0版本

然后修复它

我也犯了同样的错误。首先我更新cocoapods使用

sudo gem install cocoapods

然后安装Pod使用Pod安装命令为我工作。

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!

如果你在Podfile中删除目标的所有pod，例如:

target 'myTarget' do
pod 'great-stuff', '~> 4.0'  // you deleted this last pod
end

你需要从你的Xcode目标构建阶段手动删除这些构建步骤:

检查pod Manifest.lock 复制Pod资源

Cocoapods(当前稳定版本0.37.2)在运行pod install时不执行此清理。
