Question

我创建了一个有角度的应用程序，其中正在执行JSON.stringify，JSON.parse之类的JSON转换功能。我遇到诸如找不到名称“ JSON”的错误，并且在tsconfig.json中也出现错误，如下所示

“-lib”选项的参数必须为：“ es5”，“ es6”，“ es2015”，“ es7”，“ es2016”，“ es2017”，“ esnext”，“ dom”，“ dom.iterable” '，'webworker'，'scripthost'，'es2015.core'，'es2015.collection'，'es2015.generator'，'es2015.iterable'，'es2015.promise'，'es2015.proxy'，'es2015.reflect '，'es2015.symbol'，'es2015.symbol.wellknown'，'es2016.array.include'，'es2017.object'，'es2017.sharedmemory'，'es2017.string'，'es2017.intl'，'esnext .asynciterable”。

tsconfig.json

class UserModel {

  /// Document ID of the user on database
  String _firebaseId = ""; 
  String get firebaseId => _firebaseId;
  set firebaseId(newValue) => _firebaseId = newValue;

  DateTime _creationDate = DateTime.now();
  DateTime get creationDate => _creationDate;

  DateTime _lastUpdate = DateTime.now();
  DateTime get lastUpdate => _lastUpdate;

  String _displayName = "";
  String get displayName => _displayName;
  set displayName(newValue) => _displayName = newValue;

  String _username = "";
  String get username => _username;
  set username(newValue) => _username  = newValue;

  String _photoUrl = "";
  String get photoUrl => _photoUrl;
  set photoUrl(newValue) => _photoUrl = newValue;

  String _phoneNumber = "";
  String get phoneNumber => _phoneNumber;

  String _address = "";
  String get address => _address;
  set address(newValue) => _address = newValue;

  bool _isAdmin = false;
  bool get isAdmin => _isAdmin;
  set isAdmin(newValue) => _isAdmin = newValue;

  /// Used on first login
  UserModel.fromFirstLogin() {
    _creationDate     = DateTime.now();
    _lastUpdate       = DateTime.now();
    _username         = "";
    _address          = "";
    _isAdmin          = false;
  }

  /// Used on any login that isn't the first
  UserModel.fromDocument(Map<String, String> userDoc) {
    _firebaseId           = userDoc['firebaseId']  ?? '';
    _displayName          = userDoc['displayName'] ?? '';

    _address              = userDoc['address'] ?? '';
    _isAdmin              = userDoc['isAdmin'] ?? false;
    _username             = userDoc['username'] ?? '';
    //_lastUpdate           = userDoc['lastUpdate'] != null ? userDoc['lastUpdate'].toDate() : DateTime.now();
    //_creationDate         = userDoc['creationDate'] != null ? userDoc['creationDate'].toDate() : DateTime.now();
  }

    print('''

在compileOptions的lib中添加es5

  "compilerOptions": {
    "target": "es5",
    "module": "es2015",
    "lib": [
      "es5",
      "dom"
    ]
  }
