使用软件包管理器在Ubuntu 16.04 Server上安装NodeJS只会安装发行版（v.4）而不是LTS

Question

I have this odd problem that when I try to install NodeJS on a fresh Ubuntu Server VM.

I execute the two simple steps from the official instruction but somehow I manage to fail.

In the home directory of my user I execute curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash - which ends successfully and then sudo apt-get install -y nodejs but this results in the installation of v.4.2.6.

Output can be seen below:

Please help.

Answer 1

You probably have to run sudo apt-get update before sudo apt-get install to update the local package lists after adding the sources for 6.x. If you do that, you should see version 6 being installed.

The answer was hiding in this thread: Installing NodeJS on Ubuntu Trusty

So it must have been some kind of an issue with curl using the local network so I used wget to download like this:

wget https://deb.nodesource.com/setup_6.x

And then from the same directory:

sudo bash ./setup_6.x

And finally:

sudo apt-get install nodejs

Which did it.

You might consider using nvm to install Node instead of the distro package. This offers you more flexibility in managing your version of Node.
