同事离开度假,我试图按照他离开的说明在我们的演示服务器上设置他的应用程序.我可以在本地运行所有内容,但是在安装socket.io模块的服务器上遇到问题.

安装了python,安装了nodejs,两者都成功了.但后来我发出命令：

npm install -g socket.io

我得到的输出是：

我所在的帐户应该具有管理员权限.谷歌搜索我发现了一些建议,但似乎没有一个对我有用.尝试使用sudo进行前置命令,但得到：

[qa@umr-demo ~]sudo npm install -g socket.io
[sudo] password for qa:
sudo: npm: command not found
