xcode - 无法找到 `React-Core` 依赖的规范 `UMReactNativeAdapter`

Question

低于错误，

Analyzing dependencies
Fetching podspec for `DoubleConversion` from `../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec`
Pre-downloading: `ExpoKit` from `http://github.com/expo/expo.git`, tag `ios/2.13.0`
Fetching podspec for `Folly` from `../node_modules/react-native/third-party-podspecs/Folly.podspec`
Fetching podspec for `glog` from `../node_modules/react-native/third-party-podspecs/glog.podspec`
[!] Unable to find a specification for `React-Core` depended upon by `UMReactNativeAdapter`

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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.

我试过，

pod setup
pod install
pod install --repo-update

另外，我卸载/安装了 cocoapods再次，但仍然出现上述错误。

您可以更改您的 UMReactNativeAdapter podspec 文件，

s.dependency 'React-Core'

将“-”更改为“/”

看看这个类似的问题。
