如何在Ubuntu 14.04上升级/安装最新版本的nodejs

Question

我已经为此工作了一个小时。

摘自其正式文件：

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

然而，它从来没有为我工作过。我试图清除npm cache，甚至卸载它并再次运行这两个命令。还是不起作用。我一直有0.10.25版本

我跑：

grep -h ^deb /etc/apt/sources.list /etc/apt/sources.list.d/* 

我得到的是：

nodejs似乎不在名单上。

我该怎么办？请帮帮我

Answer 1

我终于采用了非官方/过时的方式：

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

sudo ln -sf /usr/local/n/versions/node/<VERSION>/bin/node /usr/bin/node

如何将我的nodeJS更新为最新版本？

然而，这使得我的node -v和nodejs -v有不同的版本。nodejs -v仍然返回过时的版本。我不知道这是否有任何效果。
