NB: on a separate occassion (on another 14.04 system) I failed to install Node 4 in the way described in this post and instead succeeded with the method described here.
The following worked for me in August 2016:
curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash - sudo apt-get install -y nodejs
… subsequently to the installation above I get:
$ nodejs -v v4.5.0 mperdikeas@beorn:~# $ node -v v4.5.0… with no need to setup alternatives as I had to do in the installation method described in this post.
NB: the above process failed the first time it was adapted (I suspect due to some network vagary)
NB 2: The above also installs npm so subsequently to the above I configured npm to install global packages in my home directory as also described in this post:
$ which npm /usr/bin/npm $ npm --version 2.15.9 $ which npm /usr/bin/npm $ npm --version 2.15.9 $ npm config list ; cli configs user-agent = "npm/2.15.9 node/v4.5.0 linux x64" ; node bin location = /usr/bin/nodejs ; cwd = /home/mperdikeas ; HOME = /home/mperdikeas ; 'npm config ls -l' to show all defaults. $ npm config get prefix /usr $ cd && mkdir .node_modules_global $ npm config set prefix=$HOME/.node_modules_global $ npm config get prefix /home/mperdikeas/.node_modules_global $ cat .npmrc prefix=/home/mperdikeas/.node_modules_global $ npm install npm --global /home/mperdikeas/.node_modules_global/bin/npm -> /home/mperdikeas/.node_modules_global/lib/node_modules/npm/bin/npm-cli.js npm@3.10.6 /home/mperdikeas/.node_modules_global/lib/node_modules/npm… the above process also re-installed an updated version of npm in ~/.node_modules_global so we also need to update the PATH to ensure that npm is picked-up from that location:
$ cat ~/.bashrc_thisnode export PATH=~/.node_modules_global/bin:$PATH… and ensure it works:
$ which npm /home/mperdikeas/.node_modules_global/bin/npm $ npm -version 3.10.6Concluding, as part of the above post-node installation configuration we've accomplished three things:
