[!] 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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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cocoapods再次卸载/安装，但仍然出现上述错误。
