Npm 在安装现有项目的依赖项时，我在angular中遇到错误

cli的本地系统验证：

我正在尝试运行现有的angular项目。 使用npm安装

但它在安装依赖项时给了我上述错误

我已经分享了angular for project的版本，我的系统也请看一看

该项目是使用6.1.5角版本开发的

我的本地系统上有6.0.1版本

    Your global Angular CLI version (6.1.5) is greater than your local
    version (6.0.1). The local Angular CLI version is used.

    To disable this warning use "ng config -g cli.warnings.versionMismatch false".
