我正在尝试使用 NPX create React app 创建一个 React 应用程序，并且 npm install 运行正常，但应该运行代码的 npm start 会出现错误。
这是错误

我尝试删除节点模块并删除缓存，然后再次使用 NPM INSTALL 但它们不起作用。我在这里缺少什么？
最佳答案
解决方案1
将环境变量设置为 C:\Windows\System32。
解决方案2
如果第一个步骤不起作用，请按照第二个步骤操作。导航到您的项目文件夹并输入此命令>>>
rm -rf node_modules
rm package-lock.json
rm yarn.lock
npm cache clear --force
npm install
解决方案3
降级package.json文件中的react-scripts
