我收到以下错误。当我执行“ ng build --prod --aot”

错误 找不到模块：错误：无法在“ C：\ Shruthi \ Applications \ PULSE \ Q2-error \ pulse \ Pulse-web \ node_modules \”中解析“ ../@akveo/ng2-completer/ng2-completer.ngfactory” ng2-smart-table'

当我进行构建时，一切正常。

我从昨天开始收到此错误，昨天之前一切正常。

是否由于ng2-completer或与ng build或angular版本相关的某些内容而导致错误。

下面是我的package.json
