TypeError：无法读取未定义的属性“包含”

Question

所以基本上，我在一个 Ionic 项目中，我们在两周前或多或少地成功迁移到了 3.0.0 测试版。一切正常，我可以毫无问题地进行开发。

但是今天早上，我使用的是 Ionic 3 beta CLI，并尝试安装 ConnectivityService。它不能在那个版本中工作，所以我彻底卸载了 ionic，然后，针对 ionic@latest 进行了新的安装。它在应用程序脚本上给出了一个依赖错误，所以我使用了以下命令：

npm install --save @^1.3.1

然后，我再次使用“npm install -g ionic@latest”。在那之后，一切都停止了工作。我不能再用离子做任何事情了；无论我做什么，我都会遇到同样的错误：“TypeErrpr：无法读取未定义的属性'包含'”。卸载再安装也没关系；我就是无法让它工作。

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。
