我尝试使用 npm 安装 express-generator（或 angular-cli）但不成功。 报错如下：

如果您使用代理，请确保“代理”配置设置正确。请参阅：'npm 帮助配置'

如果您在 windows 防火墙后面，则必须使用代理连接到 npm 注册表。

您可以通过两种方式创建代理

• 使用这些命令：

  npm config 设置代理 http://username:password@host:port npm config 设置 https-proxy http://username:password@host:port

• 在 C:/<path to current user> 中创建一个 .npmrc 文件并添加 http 和 https 代理

  proxy=http://username:password@host:port https-proxy=http://username:password@host:port https_proxy=http://username:password@host:port
