You need to have nodecode folder in directory else you will get
bash: /root/nodecode$: No such file or directory
Info:
apt-get is a command line interface for retrieval of packages and
information about them from authenticated sources and for
installation, upgrade and removal of packages together with their
dependencies.
npm is installed with Node.js npm is distributed with Node.js- which
means that when you download Node.js, you automatically get npm
installed on your computer. For checking the version of npm
StepI Install your nodejs
https://nodejs.org/en/
Ubuntu
Run the following on your command line to install the source for nodejs
curl -sL https://deb.nodesource.com/setup | sudo -E bash -
Then, run this to get the latest nodejs package
sudo apt-get install -y nodejs
Step II
Check that you have node and npm installed
To check if you have Node.js installed, run this command in your terminal:
node -v
To confirm that you have npm installed you can run this command in your terminal:
npm -v
A note on versions
npm versions
npm is a separate project from Node.js, and tends to update more
frequently. As a result, even if you’ve just downloaded Node.js (and
therefore npm), you’ll probably need to update your npm. Luckily, npm
knows how to update itself! To update your npm, type this into your
terminal:
npm install npm@latest -g
Node versions and Long Term Support Node.js has lots of versions! To
use Node.js, and therefore npm, effectively, you’ll want to make sure
that you are on a version that is supported by the Node.js team. In
general, you should use the version of Node.js labelled “LTS”.
Use a Node.js version manager Software is always changing, and so it’s
often a good practice to use a version manager to help account for
this change. For this reason (and many others!) we recommend that you
use a version manager for your Node.js installation. There are many
great options; here are a few*:
NVM
