获取：错误 TS1128：预期的声明或语句。 在 ReactJS 和 TypeScript 应用程序中

Question

Here is my current code for the new component I created which is causing this error to be throw.

Failed to compile.

./src/components/Hello.tsx (5,1): error TS1128: Declaration or statement expected.

I've checked other answers and haven't found the actual issue yet.

// src/components/Hello.tsx

import * as React from 'react';

export Interface Props {
  name: string;
  enthusiasmLevel?: number;
}

function Hello({ name, enthusiasmLevel = 1 }: Props) {
  if (enthusiasmLevel <= 0) {
    throw new Error('You could be a little more enthusiastic. :D');
  }

  return (
    <div className="hello">
      <div className="greeting">
        Hello {name + getExclamationMarks(enthusiasmLevel)}
      </div>
    </div>
  );
}

export default Hello;

// helpers

function getExclamationMarks(numChars: number) {
  return Array(numChars + 1).join('!');
}

Answer 1

Change

export Interface Props {

to

export interface Props {
