因此，我花了几个小时尝试自己修复这个问题，但我觉得情况变得更糟了。我正在运行 Kbuntu 12.10，并尝试以非 root 用户身份安装 nodejs 和 npm，以便我可以安装游戏闭包框架。我以 root 身份安装了 node 和 npm 版本。然后尝试通过以下说明再次安装它（不删除旧版本）：http://tnovelli.net/blog/blog.2011-08-27.node-npm-user-install.html
现在当我输入时，which npm我什么也得不到。但是当我输入时，which node我得到了/home/myusername/.local/bin/node。所以我假设节点已正确安装。
当我输入时npm -v
我得到：
The program 'npm' is currently not installed. You can install it by typing:
sudo apt-get install npm
所以我输入sudo apt-get install npm
响应是：

我该如何修复这个问题，以便我可以根据上面的链接安装 npm？
编辑：经过更多搜索后，我尝试了sudo apt-get clean && sudo apt-get update
，即使在那之后，我在尝试 apt-get npm 后仍然收到相同的消息
