I have little knowledge of Ubuntu 14.04.

I need to install Node.js. The Ubuntu I am using is a big system for an organization so I don't have sudo access, but I found that npm 1.3.10 is installed.

I am looking for a sequence of commands to install Node.js into my user directory. I have downloaded Node.js from here on nodejs.org (LTS version, 64 bit) in ~/Downloads/node-v8.9.1-linux-x64.tar.xz. What do I do next?

In order to install Node.js and npm locally without having to use sudo open the terminal and type:

echo 'export PATH=$HOME/local/bin:$PATH' >> ~/.bashrc

. ~/.bashrc

mkdir ~/local

mkdir ~/node-latest-install

cd ~/node-latest-install

wget -c http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1

./configure --prefix=~/local

make install 

wget -c https://www.npmjs.org/install.sh | sh  

The curl package is not installed in Ubuntu by default. If you don't have curl installed on your system, replace all instances of curl in the install.sh file with wget -c and save the changes to the install.sh file before running it.

This will install node-v9.2.0 which is a later version of Node.js than the file you already downloaded.

I workout this way - in 2 steps.

Step 1: Download and extract nodejs binaries

# create a directory where you want to install node js

mkdir ~/nodejs-latest



# download and extract nodejs binaries into the created directory

cd ~/nodejs-latest

wget -c http://nodejs.org/dist/node-latest.tar.gz | tar xz --strip-components=1

# append the following lines to the ~/.bashrc file

export NODE_HOME=~/nodejs-latest

export PATH=$PATH:$NODE_HOME/bin



# refresh environment variables

source ~/.bashrc

You can then verify the nodejs installation with node --version and npm --version.

I like to use ubuntu groups to achieve this. It's quite simple.

1. 
   

   First install nodejs and npm using apt-get

   
   
   

   sudo apt-get update && sudo apt-get install nodejs npm

   
   


2. 
   

   Figure out who is logged in i.e username, run following command to see it in terminal

   
   
   

   whoami

   
   


3. 
   

   You can see the list of groups you are assigned by using a very simple command, normally the first group is your username itself

   
   
   

   groups

   
   


4. 
   

   Run following to allow access to logged in user

   
   
   

   sudo chmod 777 -R /usr/local && sudo chgrp $(whoami) -R /usr/local

   
   


5. 
   

   Update npm and nodejs

   
   
   

   npm install -g npm

   
   

You are allset, your user can run npm commands without sudo

You can also refer to npm throws error without sudo.
