ubuntu 12.04 LTS中未安装npm

Question

pp@pp-desktop:~$ sudo apt-get install npm

正在读取包列表...依赖关系树构建完成

正在读取状态信息...完成后，无法安装某些包。这可能意味着您请求了一种不可能的情况，或者如果您使用的是不稳定的发行版，那么一些所需的包还没有创建或移出传入的包。以下信息可能有助于解决此问题：

The following packages have unmet dependencies:
 npm : Depends: nodejs but it is not going to be installed
       Depends: nodejs-dev

我通常在Ubuntu中安装NodeJS和NPM，并遵循以下教程(如何使用PPA安装)：https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-an-ubuntu-14-04-server

我已经在Ubuntu 12.04 LTS中尝试过了，没有任何问题。

警告：尝试在干净的Ubuntu中安装。

希望它能为你工作！
