问题描述
今天，我突然开始收到此错误 尝试在我的angular 4应用程序中添加组件(ng g c abc)时，无法读取未定义的'NullLogger'属性" .当我在google上搜索它时，有人建议我们需要将cli版本更新为1.4.10.但是问题是为什么对于1.4.10以下的所有angular/cli版本，我们现在都会出现此错误?.我现在不想更新我的CLI版本.有人知道为什么会这样吗?
Today, sudeenly I start getting this error "Cannot read property 'NullLogger' of undefined" while trying to add a component ( ng g c abc) in my angular 4 app. When I searched it on google, people are suggesting that we need to update our cli version to 1.4.10 . But the question is why we are getting this error now for all angular/cli version below 1.4.10? . I do not want to update my CLI version now. Does anyone know why is it happening??
