Question

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

npm ERR！代码E404

npm ERR！找不到404：@ angular / router @ 5.2.0

每次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

我确实有互联网连接
我已经npm config set registry https://registry.npmjs.org/。
我删除了node_modules文件夹
我删除了缓存：npm cache clean --force
npm search找到了模块：

C：\ windows \ system32＆gt; npm search @ angular / router

还有什么可能是错的？

Answer 1

问题是由包含行.npmrc的本地文件always-auth = true引起的。删除此行可解决此问题。我不知道404错误是如何与身份验证相关的，但是注意到在我切换到镜像注册表之后，它突然报告了E401而不是官方注册表中的E404。

Answer 2

就我而言，通过在命令中添加@latest可以解决此问题。

npm install -g @ angular / cli @ latest

安装角度代表时，NPM安装结果为404
