我试图用gh-pages部署我的React应用程序，但是我遇到了这个错误：“ file”参数必须是字符串类型。收到的类型未定义。

起初，我以为是我的代码，所以我制作了另一个没有修改的create-react-app，尝试使用npm run deploy命令进行部署，但再次收到此错误消息。

我的package.json（我已经添加了homepage链接，predeploy和deploy脚本以及gh-pages依赖项）：

  "name": "test-deploy",
  "version": "0.1.0",
  "private": true,
  "homepage": "https://vnsteven.github.io/test-deploy/",
  "dependencies": {
    "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",
    "eject": "react-scripts eject",
    "predeploy": "npm run build",
    "deploy": "gh-pages -d build"
  },
  "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"
    ]
  }
}

错误输出：

此错误消息来自我全新的React应用程序。只有我的package.json已被修改。
