离子2 - 观看失败：配置为观看以下路径的手表无法启动

Question

我一直试图让Ionic watch工作，但我一直在收到错误。我使用以下命令创建了一个全新的应用程序：

ionic start my-app --v2

这似乎工作正常，然后我尝试提供应用程序

ionic serve -p $PORT

但是，我收到以下错误

watch failed: A watch configured to watch the following paths failed to start. It likely that a file 
        referenced does not exist: /home/ubuntu/workspace/my-app/src/**/*.(ts|html|s(c|a)ss) 

我可以看到src文件夹确实存在于错误中显示的路径中。有没有办法可以解决这个错误？我正在使用C9 IDE并使用以下命令安装Ionic

sudo npm install ionic cordova -g

这是我的package.json，以防需要：

我有同样的错误，我通过删除node_modules目录解决它并运行npm install
