无法在Ubuntu上安装npm 12.04

Question

我想将我的nodejs和npm 1.4升级到最新版本。我设法将我的nodejs升级到10.0.40，但我的npm无法更新。所以我决定一起删除它并重新安装最新版本。现在，我不仅可以安装最新版本，但我不能安装我以前的一个。每次我尝试安装它给我这个错误：

$ sudo apt-get install npm 
Reading package lists... Done

Some packages could not be installed. This may mean that you have 
requested an impossible situation or if you are using the unstable

     Depends: node-tar but it is not going to be installed 
     Depends: node-which but it is not going to be installed

我怎么能安装最新版本，当我根本没有它？

基于相对有限的信息，我建议您从NodeSource ppa中完全删除并重新安装节点。

这将是sudo apt-get purge nodejs删除节点，然后按照instructions here。

对于Ubuntu的，命令的全序列卸载并重新安装电流+的NodeJS NPM将是（节点4.x版）：

sudo apt-get purge nodejs 
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash - 
sudo apt-get install -y nodejs 

免责声明

这将完全删除您的安装Node.js，然后从另一个（最新）源重新安装。这个过程应该是直截了当的，但如果你不明白它在做什么，使用它需要你自担风险。
