1.执行ng g component 组件名，报错：

Error: More than one module matches. Use skip-import option to skip importing the component into the closest module.

More than one module matches. Use skip-import option to skip importing the component into the closest module.

解决思路：按照提示执行ng g component 组件名 --skip-import，报错信息变了，如下：

Error: dryRunSink.commit(...).ignoreElements is not a function

dryRunSink.commit(...).ignoreElements is not a function

最终解决办法为：

先执行：npm i @angular-devkit/schematics@0.0.45 @angular/cli --no-sav

再执行：ng g component 组件名 --skip-import

问题解决！！
