TypeErrpr:无法读取未定义的属性'includes‘

Question

所以基本上，我在一个离子项目中，我们在两周前成功地迁移到了3.0.0测试版。一切都很正常，我可以毫无问题地进行开发。

但今天早上，我使用的是IONIC3Beta CLI，并尝试安装ConnectivityService。它不能在那个版本中工作，所以我执行了一个干净的ionic卸载，然后，针对ionic@latest进行了一个新的安装。它在app-scripts上给出了一个依赖错误，所以我使用了以下命令：

npm安装--save @^1.3.1

然后，我再次使用"npm install -g ionic@latest“。在那之后，一切都停止了。我不能再用ionic做任何事情了；无论我做什么，我都会遇到同样的错误："TypeErrpr: Cannot read property 'includes‘of undefined“。如果我把它卸载并重新安装也没关系，我只是不能让它工作。

你知道这可能是什么原因吗？

您的npm包已过期。我建议安装npm-check-updates，然后使用'ncu -u‘更新您的package.json文件。
