ng build --prod 下出现的问题

[daonatural]

我用的是angular-cli开发项目，用了ngx-echarts后，没有问题，页面也可以正常显示，当我重新ng serve的时候，会出现异常
ERROR in Error encountered resolving symbol values statically. Calling function 'ɵmakeDecorator', function calls are not supported. Co nsider replacing the function or lambda with a reference to an exported function, resolving symbol NgModule in /node_modules/_ngx-echarts@1.2.0@ngx-echarts/node_modules/@angular/core/core.d.ts, resolving symbol Angular EchartsModule in /node_modules/_ngx-echarts@1.2.0@ngx-echarts/index.d.ts, resolving symbol AngularEchartsModule in /node_modules/_ngx-echarts@1.2.0@ngx-echarts/index.d. ts，
再次complie又成功了，所以就没放在心上。

但当我用ng build --prod 打包项目的时候就会抛出同样的错误：

@freeWd 我自己的多个项目中也都是使用了ngx-echarts，并且使用ng build --prod是成功的。所以没有能够复现出你的问题。我怀疑和你本地的开发环境有关系，请试一下清空node_modules目录，然后重新npm install一次？

谢谢你的回复，这两天没有上网，回家过节了。所以没能及时回复你，表示歉意。
这个问题昨天才解决，是因为angular-cli的版本问题导致的，升级就没报这个错了。 ♪(^∇^*)
