Firebaseを用いた、facebookログインの実装における、SDKのimportエラー

firebaseを用いてfacebookログインを実装しようとしています。

とある講座の教材として実装しているのですが、
cocoapodsで下記ライブラリをinstallし、

ruby
1# Uncomment the next line to define a global platform for your project
2# platform :ios, '9.0'
3
4target 'Swift5FacebookLoginWithFirebase_3' do
5  # Comment the next line if you don't want to use dynamic frameworks
6  use_frameworks!
7
8  # Pods for Swift5FacebookLoginWithFirebase_3
9  pod 'Firebase/Auth'  
10  pod 'FacebookSDK'
11  pod 'Firebase/Core'
12  pod 'FacebookCore'
13  pod 'FacebookLogin'
14  pod 'FacebookShare'
15  pod 'SDWebImage/WebP'
16
17end
18```swift

20viewControllerにて、
21下記のように
22importしていますが、下記画像のようにFBSDKCoreKItがNo such module~となります。
23なぜでしょうか？

        UserDefaults.standard.set(1, forKey: "loginOK")
        UserDefaults.standard.set(self.displayName, forKey: "displayName")
        UserDefaults.standard.set(self.pictureURLString, forKey: "pictureURLString")
    }
    
}

func loginButtonDidLogOut(_ loginButton: FBLoginButton) {
    <#code#>
}

// //github試験用
// func Log() {
// print("gittest")
// }
//
// //さらに変更
// func Log2() {
// print("gittest")
// }

}


pod install で下記のようにwarningがでます。
ちなみに、rbenvでrubyを2.7.0に最近しました。関係があるのでしょうか？
