Question

我正在尝试将角度5从角度更新为角度6。
因此，我正在执行以下步骤。 Want to upgrade project from Angular v5 to Angular v6
当我执行此命令ng update @ angular / cli和ng update @ angular / core时，我遇到以下错误。
你能告诉我如何解决它吗？
在下面提供我的package.json

C:\codebase\branches\project>ng update @angular/cli

这通常是代理的npm问题，实际上不是CLI问题。

看看Using npm behind corporate proxy .pac

基本上，您需要确保已配置npm以通过代理工作，然后ng cli应该不会出现连接问题。

npm config set proxy "http://domain\username:password@servername:port/"

请注意，这会将您的密码保存在配置文件中，因此完成后，您可能希望像这样删除已保存的密码”

npm config delete proxy
