以下软件包具有未满足的依赖项：nodejs：冲突：npm

我遵循了这个要旨https://gist.github.com/Goddard/5500157来安装nodejs和npm，但是运行它之后，既不能运行node --version也不可以运行npm --version，从而导致找不到命令错误。我能够卸载nodejs，但是必须进入脚本中描述的temp目录并进行make卸载才能使npm离开。

现在，尝试再次安装nodejs和npm时，我改用此链接http://www.andreagrandi.it/2013/02/08/how-to-install-latest-stable-node-js-on-ubuntu/，但是，如果我尝试同时安装nodejs和npm，则会收到此错误消息。

sudo apt-get install nodejs npm

The following packages have unmet dependencies:
   nodejs : Conflicts: npm
E: Unable to correct problems, you have held broken packages.

如果我只是安装nodejs，那可以正常工作。

sudo apt-get install nodejs

node --version
v0.10.15

但是现在，如果我尝试安装npm，则会显示此错误消息

sudo apt-get install npm 

The following packages have unmet dependencies:
npm : Depends: nodejs (>= 0.6.19~dfsg1-3) but it is not going to be installed

我正在使用Ubuntu 13.04。任何帮助表示赞赏。我对node.js和npm不太了解。我正在尝试开始学习如何使用这些功能，因此我的经验不足可能正在显示出来。

nodejs从PPA安装的软件包npm自v0.10.0起包含。由于您拥有v0.10.15，因此在运行sudo apt-get install nodejs时还安装了npm。尝试运行npm以确认。
