无法在 Linux 的 Windows 子系统上运行反应服务器（ubuntu）

Question

所以我试图在 ubuntu 上使用 reactjs 开发服务器从 Windows ZEDC9F0A5A373648 子系统运行

当我跑步时

sudo npm start

我收到这样的错误：

启动开发服务器...

      ^

我试过了：

sudo npm cache clear --force
sudo rm -rf node_modules
sudo npm install
sudo npm start

但我仍然收到错误

我也试过：

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

但它也不能解决任何问题

Answer 1

没关系，我试图在根文件夹上安装 npm，我应该在文件夹 app 上安装 npm

Answer 2

所以我遇到了一个新问题，我正在尝试在 Port=80 上运行 reactjs

但我不能使用：

sudo PORT=80 npm start

它返回上面的错误

奇怪的是，如果我只使用它就可以完美运行

npm start
