当我运行时，npm run build我收到此错误：

ERROR in ./src/client.js 7:2\nModule parse failed: Unexpected token (7:2)\nFile was processed with these loaders:\n * ./node_modules/jshint-loader/index.js\nYou may need an additional loader to handle the result of these loaders.\n| \n| const component = (\n>   <Router history={browserHistory}>\n|     {routes}\n|   </Router>\n @ multi babel-polyfill ./src/client.js main[1]\n

./src/client.js（带有警告browserHistory-- 无法解析符号 \'browserHistory\' ）

我有很多城市都有这样的物体：

[{id: 1, name: 'New York'}, {id: 2, name: 'London'} ...]

我的值是id。

我将数组中的元素（名称）放入选择列表。但我需要添加第一个选项，其中包含数组（名称）中的值，该选项具有相应的 id，但我无法使其工作。

我的组件：

const propTypes = {  
  cities: PropTypes.array,  
  enteredEvent: PropTypes.array  
};

class newEvent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      showInOption: ''
    };
    this.handleDictionary = this.handleDictionary.bind(this);
    this.searchTypeEvent = this.searchTypeEvent.bind(this);
  }

  componentDidMount() {
    this.searchTypeEvent();
  }

  handleDictionary(e) {
    ...
  }

  searchTypeEvent() {
    if (this.props.enteredEvent.cityid !== null && this.props.enteredEvent.cityid !== undefined) { // if I have id value
      const type = this.props.cities.find(el => el.id …

当我运行时eslint .出现错误：

Error: .eslintrc.js \xc2\xbb eslint-config-standard-with-typescript:\n    Configuration for rule "@typescript-eslint/restrict-plus-operands" is invalid:\n    Value {"skipCompoundAssignments":false} should NOT have additional properties.\n

我在配置中禁用了“@typescript-eslint/restrict-plus-operands”规则：

rules: {\n  ...\n  '@typescript-eslint/restrict-plus-operands': 'off',\n}\n

但它不起作用，我得到同样的错误。

有什么问题？

软件包版本：

"@typescript-eslint/eslint-plugin": "^5.62.0",\n"@typescript-eslint/parser": "^6.4.1",\n"eslint": "^8.48.0",\n"eslint-config-prettier": "^9.0.0",\n"eslint-config-standard-with-typescript": "^39.0.0",\n"eslint-plugin-import": "^2.28.1",\n"eslint-plugin-n": "^16.0.2",\n"eslint-plugin-prettier": "^5.0.0",\n"eslint-plugin-promise": "^6.1.1",\n"typescript": "^5.2.2",\n

节点 v14.18.2

npm v6.14.15

UPD

将“@typescript-eslint/eslint-plugin”更新到6.4.1版本后，出现了新的错误：

/node_modules/@typescript-eslint/parser/node_modules/@typescript-eslint/scope-manager/dist/referencer/ClassVisitor.js:123\n        withMethodDecorators ||=\n                             ^^^\nSyntaxError: Unexpected token '||='\n

我需要添加对象列表,但我无法理解如何正确地做到这一点.我从控制台获得的每个新对象.怎么解决？

我的尝试:

namespace ExampleCars
{
    public class Car
    {
        public string name;
        public int speed;
        public Car(string name, int speed)
        {
            this.name = name;
            this.speed = speed;
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            string name;
            int speed, elements;
            List<Object> cars = new List<Object>();

            elements = Convert.ToInt32(Console.ReadLine());
            if (elements > 0)
            {                
                for (int i = 0; i < n; i++)
                {                    
                    name = Convert.ToString(Console.ReadLine());                    
                    speed = Convert.ToInt32(Console.ReadLine());                    
                    Car newCar = new Car(name, speed);
                    cars.Add(newCar);
                }
            } …
