似乎是gh-pages 2.1中的错误。
我通过将gh-pages降级到2.0版解决了我的问题：
yarn add gh-pages@2.0 -D` // ornpm install -D gh-pages@2.0解决方法
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 rundeploy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' ] }}

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。
