不能使用JSX，除非‘--jsx’-作出反应

Question

    }

Login.tsx

   interface IUserLoginInformation {
      username: string;
      password: string;
    }

    const Login = () => {
      const {
        register,
        handleSubmit,
        watch,
        formState: { errors }
      } = useForm<IUserLoginInformation>();
      const history = useHistory();
    
      const [users, setUsers] = React.useState([]);
      
    
      const onSubmit: SubmitHandler<IUserLoginInformation> = data =>
        fetchLoginDeatils();
    
      return (
        <form onSubmit={handleSubmit(onSubmit)}>
          <input defaultValue="test" {...register("username")} />{" "}
          {/* register your input into the hook by invoking the "register" function */}
          {/* include validation with required or other standard HTML validation rules */}
          <input {...register("password", { required: true })} />
          {/* errors will return when field validation fails  */}
          {errors.password && <span>This field is required</span>}
          <input type="submit" />
        </form>
      );
    };
    export default (Login);

在上面的代码中，我得到了以下错误:我在互联网上尝试了所有可能的选项。但是没有什么是changed.In登录代码，我使用javascript和脚本.I更改"jsx"："react-jsx" to "jsx"：“put”。

 Cannot use JSX unless the '--jsx' flag is provided.

Answer 1

下面的内容是错误的，因为它排除了.tsx文件，比如Login.tsx

  "include": [
    "./src/**/*.ts"
  ]

修复

改为：

  "include": [
    "src"
  ]

附加提示

更改后的

• 尝试重新启动您的IDE +终端以获取tsconfig.json。
• 确保没有其他tsconfig.json文件。
