Node.js安装socket.io时出现npm错误

Question

我是一个新的node.js开发者。我正在尝试编写一个简单的聊天项目。因此，我想通过NPM安装socket.io，但是我遇到了这个错误。

我使用的是Ubuntu 12.04。

ubuntu@Ubuntu-1210:~/Masaüstü/blog$ npm install socket.io
npm http GET https://registry.npmjs.org/socket.io

你尝试过访问 https://dev59.com/kGcs5IYBdhLWcg3wXSyU 吗？ - bbill

谢谢，问题已经解决了 :) - Olkunmustafa

Answer 1

像我在上面评论中发布的链接中的答案一样，我建议首先运行

npm config set registry https://registry.npmjs.org/

- bbill

你也可以使用不同的镜像源，比如Nodejitsu托管的镜像源：npm config set registry https://registry.nodejitsu.com/ - 3rdEden

这是不安全的，因为您没有使用https。 - AzizAhmad

Answer 2

建议使用sudo。

sudo npm install socket.io
