我正在尝试按照这些步骤开始我的第一个离子项目：Ionic framework get started page
但是当我在终端ionic serve写作时（步骤3），即使我在http://localhost:8100运行开发服务器，我也收到此错误消息（我的应用程序正在运行但我仍然遇到此错误消息）：
TypeError: msg.trim is not a function

同样在设置时我编写命令sudo ionic start myApp tabs我得到了这个：Running command - failed! [ERROR] An error occurred while running npm install (exit code 1):
终端中的完整错误消息（我在macOS上）是：
