I have the same issue. Basically, I am using node v10+ but my project was created in v8.11.4. All the modules were used according to the older version(v8), that's why I am facing the issue. So there are two solutions either update your module or downgrade the node.
我有同样的问题。基本上，我使用的是 node v10+，但我的项目是在 v8.11.4 中创建的。所有模块都是根据旧版本（v8）使用的，这就是我面临这个问题的原因。所以有两种解决方案，要么更新你的模块，要么降级节点。
I have solved by downgrading the node from v10 to v8. Because some of the modules are not possible to update due to project dependency.
我已经通过将节点从 v10 降级到 v8 来解决。因为部分模块由于项目依赖无法更新。

Little late, but for any out there struggling, I came across this error by creating the React app without using sudo. Using sudowhile running npx create-react-app app-namefixed the issue.
有点晚了，但对于任何在那里挣扎的人，我通过创建 React 应用程序而不使用sudo. 使用sudo在运行npx create-react-app app-name固定的问题。

If you are running on Windows and have IIS running on your machine, ensure the IIS server is stopped if you are trying to run on port 8080. You can also change the port to not bring IIS into it.
如果您在 Windows 上运行并且在您的计算机上运行 IIS，如果您尝试在端口 8080 上运行，请确保 IIS 服务器已停止。您还可以更改端口以不将 IIS 带入其中。
npm start -- --port 8000
