Jest无法正常运行Create-React-App“无法从componentY找到模块nodeModuleX”

Question

我正在尝试开始测试使用Jest通过Create React App创建的项目中的组件。我为一个组件创建了一个简单的测试文件，并且从与我要测试的组件甚至不相关的组件中获取“错误”。我正在使用Create React App，因此无法更改Jest的配置。

那是测试文件

/** Home.test.js */

import React from 'react';
import ReactDOM from 'react-dom';
import Home from '../../components/Home';

test('renders without crashing', () => {
    const div = document.createElement('div');
    ReactDOM.render(<Home />, div);
 });

那是错误

FAIL  src\__tests__\components\Home.test.js
  ? Test suite failed to run

    Cannot find module 'signature_pad' from 'Signature.jsx'

      at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:179:17)
      at Object.<anonymous> (src/components/common/inputs/Signature.jsx:3:22)

如果在组件Signature.jsx上注释代码的导入行，则会从另一个组件收到另一个错误：
