我刚刚开始一个反应本机项目。然而这个问题却困扰了我一天。我尝试了所有可能的方法来解决它。例如，
sudo gem uninstall cocoapods
rvm uninstall
brew install cocoapods
然而，我却没有运气。我想指出，我可以pod --version在其他路径下，但当我尝试pod在我的项目路径下时会出现问题。我还尝试将rvm默认版本设置为2.7.5，但问题仍然发生。另外，我没有使用Apple M1

我是Firebase的新手,我想存储提供者照片网址但是它出现错误'只能存储NSNumber,NSString,NSDictionary和NSArray类型的对象.' 我尝试了不同类型的方法,但它似乎不适用于示例let profilePicUrl = profile.photoURL as String或let profilePicUrl = NSString(NSURL: profile.photoURL)
这是我的方法
func createFirebaseUser(){
let key = ref.child("user").childByAutoId().key
if let user = FIRAuth.auth()?.currentUser{
for profile in user.providerData{
let uid = profile.uid
let providerID = profile.providerID
let displayName = profile.displayName
let email = ""
let profilePicUrl = profile.photoURL
//let userDict :[String : AnyObject] = ["name": username!"profilePicUrl": profilePicUrl!]
