我试图将react应用程序部署到 gh-pages。我以前做过，但这是我第一次遇到这种错误。它说

“文件”参数必须是字符串类型。接收类型未定义

我尝试删除 node_modules 文件夹并使用 npm install 重新安装所有软件包，但仍然发现相同的错误

下面是我的 package.json 文件

{
      "name": "qrummy",
      "version": "0.1.0",
      "homepage": "https://quiph.github.io/QRummy/",
      "private": true,
      "dependencies": {
        "firebase": "^6.2.4",
        "gh-pages": "^2.1.0",
        "react": "^16.8.6",
        "react-dom": "^16.8.6",
        "react-scripts": "3.0.1"
      },
      "scripts": {
        "start": "react-scripts start",
        "build": "react-scripts build",
        "test": "react-scripts test",
        "predeploy": "npm run build",
        "deploy": "gh-pages -d build",
        "eject": "react-scripts eject"
      },
      "eslintConfig": {
        "extends": "react-app"
      },
      "browserslist": {
        "production": [
          ">0.2%",
          "not dead",
          "not op_mini all"
        ],
        "development": [
          "last 1 chrome version",
          "last 1 firefox version",
          "last 1 safari version"
        ]
      }
    }

这是我的主要 index.js 文件

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import * as serviceWorker from './serviceWorker';

ReactDOM.render(<App />, document.getElementById('root'));

// If you want your app to work offline and load faster, you can change
// unregister() to register() below. Note this comes with some pitfalls.
serviceWorker.unregister();

错误输出如下

> gh-pages -d build
