node.js - 安装 Angular deps 时 NPM 安装导致 404

问题描述

我安装了最新的 node.js 8.x 和 npm 5.6.0。尝试执行时npm install，我不断收到以下错误：

npm 错误！代码 E404

npm 错误！404 未找到：@angular/router@5.2.0

每次我重试安装时失败的模块都不同，但最常见的是@angular/forms@5.2.0,@angular/animations@5.2.0和@angular/platform-browser@5.2.0

C:\windows\system32>npm search @angular/router

还有什么可能是错的？

解决方案

问题是由.npmrc包含该行的本地文件引起的always-auth = true。删除此行解决了该问题。我不知道 404 错误与身份验证有何关系，但注意到我切换到镜像注册表后，它突然报告 E401 而不是像官方注册表那样的 E404。
