所以基本上，我在一个Ionic项目中，我们或多或少在两周前成功迁移到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，我正在使用Ionic 3 beta CLI，并尝试安装ConnectivityService。它无法在该版本中工作，因此我执行了ionic的完全卸载，然后进行了旨在ionic@latest的新安装。它在应用程序脚本上给出了依赖错误，所以我使用了以下命令：
npm 安装 --save @^1.3.1
然后，我再次使用了"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'"。如果我卸载它并重新安装它并不重要;我只是无法让它工作。
你知道是什么原因造成的吗？

你的 npm 包已经过时了。我建议安装 npm-check-updates，然后用"ncu -u"更新你的 package.json 文件。
