如果您使用代理，请确保正确设置了“代理”配置。 请参阅：“ npm帮助配置”

如果您位于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

• 使用以下命令：

  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>创建一个.npmrc文件，并添加http和https代理

  代理= http：//用户名：密码@主机：端口 https-proxy = http：//用户名：密码@主机：端口 https_proxy = http：//用户名：密码@主机：端口
