无法更新nodejs ubuntu 15.01的版本

Question

我不明白为什么即使我在nodejs网站上写完全相同的行也无法实现， nodejs文档说

for Alternatively, for Node.js v5:

curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -
sudo apt-get install -y nodejs

当我按照指示说时；

如何安装最新版本？

Answer 1

检查当前的Node.js版本：

node -v

强制清理缓存：

sudo npm cache clean -f

安装n模块：

sudo npm install -gn

安装最新的Node.js：

sudo n stable

设置二进制链接（将7.6.0更改为安装的任何版本）：

sudo ln -sf /usr/local/n/versions/node/7.6.0/bin/node /usr/bin/node

再次检查Node.js版本：

node -v

您可以检查此链接 。

Answer 2

您可以使用https://github.com/tj/n

sudo npm install -g n
sudo n latest

Answer 3

您是否在代理环境中？ 如果是这样，请使用“ sudo -E”代替“ sudo”。

$ sudo n stable --> NG
$ sudo -E n stable --> Maybe OK... (I hope so.)
