无法读取未定义的属性“NullLogger"(angular/cli 1.4.7) [英] Can not read property 'NullLogger' of undefined (angular/cli 1.4.7)

问题描述

今天，我突然开始收到这个错误尝试在我的 angular 4 应用程序中添加组件 (ng g c abc) 时，无法读取未定义的属性 'NullLogger'".当我在 google 上搜索时，人们建议我们需要将 cli 版本更新到 1.4.10 .但问题是为什么我们现在为 1.4.10 以下的所有 angular/cli 版本收到此错误?.我现在不想更新我的 CLI 版本.有谁知道为什么会这样??

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??

以下是我的 package.json 文件，

推荐答案

我做了以下来解决问题，

I did following to resolve the issue,

全局卸载@angular/cli

Uninstall @angular/cli globally

npm uninstall -g @angular/cli

本地卸载@angular/cli

Uninstall @angular/cli locally

npm uninstall --save-dev @angular/cli

清除缓存，

npm 缓存清理

再次全局和本地安装@angular/cli

install @angular/cli globally and locally again

npm install -g @angular/cli@latest

之后一切正常.
