安装angular-cli1.6.4警告：npm WARN @schematics/angular@0.1.13 requires a peer of @angular-devkit/schematics@0.0.46 but none was installed.

angular-cli升级到最新版本：

$ npm uninstall -g angular-cli
$ npm install -g @angular/cli@latest

最新版本为：Angular CLI 1.6.4

安装后警告提示：

npm WARN @schematics/angular@0.1.13 requires a peer of @angular-devkit/schematics@0.0.46 but none is installed. You must install peer dependencies yourself.
npm WARN @schematics/schematics@0.0.13 requires a peer of @angular-devkit/schematics@0.0.46 but none is installed. You must install peer dependencies yourself.

按提示先安装@angular-devkit/schematics@0.0.46

npm install -g @angular-devkit/schematics@0.0.46

卸载angular-cli后重新安装，仍然报以上警告。

在angular-cli的issue上开了一个bug：[bug] global angular-cli install produces peer warnings

angular1.6.4版有很多问题，已经在angular-cli 1.6.5修复。
