在Ubuntu上安装Node.js

Question

sudo apt-get install python-software-properties
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs npm

Failed to install some packages. This may mean that
you requested an impossible situation or if you are using the distribution
distribution that some required packages have not yet been created or been
been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
nodejs: Conflicts: npm
E: Failed to correct problems, you have held broken packages.

然后卸载ppa:chris-lea/node.js，尝试第二个选项：

sudo apt-get install node.js
sudo apt-add-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs npm

同样的错误，终端说npm是最新版本，但它也显示了我在顶部显示的文本。我认为问题是ppa:chris-lea/node.js，但我不知道如何解决它。

Answer 1

只需按照这里给出的说明进行操作：

安装示例：

sudo apt-get install python-software-properties python g++ make
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

它在当前稳定的Ubuntu上安装当前稳定的节点。Quantal(12.10)用户可能需要安装software-properties-common包才能使用add-apt-repository命令:sudo apt-get install software-properties-common
