How to Install Node.js and npm on Ubuntu 18.04
Npm is the default bundle director for Node.js and the world's biggest programming library.
In this instructional exercise, we will show you a few unique methods of introducing Node.js and npm on Ubuntu 18.04. Similar guidelines apply for any Ubuntu-based dispersion, including Kubuntu, Linux Mint and Elementary OS.
On the off chance that you need Node.js just as a nearby runtime for conveying Node.js applications then the least complex alternative is to introduce Node.js from the NodeSource archive. Designers ought to incline toward introducing Node.js utilizing the NVM content.
Pick the establishment alternative that is suitable for your current circumstance. It is ideal to counsel the documentation of the Node.js application that you use to discover which Node.js variants are upheld.
Installing Node.js and npm from NodeSource
NodeSource is an organization centered around giving endeavor grade Node backing and they keep an archive containing the most recent renditions of Node.js.
Utilize this vault on the off chance that you need to introduce a particular adaptation of Node.js. At the hour of composing, NodeSource store gives the accompanying adaptations - v14.x, v13.x, v12.x, and v10.x. We'll introduce the current LTS rendition of Node.js, form 12.
To introduce Node.js and npm from the NodeSource store, follow these means:
Empower the NodeSource store by running the accompanying twist order as a client with sudo advantages :
curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
The order will add the NodeSource marking key to your framework, make an adept sources storehouse document, introduce every single important bundle and revive the able reserve.
On the off chance that you need to introduce another form, for instance 14.x, simply change setup_12.x with setup_14.x
When the NodeSource storehouse is empowered, introduce Node.js and npm by composing:
sudo apt install nodejs
The nodejs bundle contains both the hub and npm doubles.
Check that the Node.js and npm were effectively introduced by printing their adaptations:
Installing Node.js and npm using NVM
NVM (Node Version Manager) is a slam content used to deal with different dynamic Node.js adaptations. With NVM you can introduce and uninstall a particular Node.js form you need to utilize or test.
To introduce Node.js and npm utilizing NVM on your Ubuntu framework, play out the accompanying advances:
1. Installing NVM (Node Version Manager) script
To download and introduce the nvm content run:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
The order above will clone the NVM vault from Github to the ~/.nvm index:
=> Close and reopen your terminal to start using nvm or run the following to use it now:
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
As the yield above says, you should either close and return the terminal or run the orders to add the way to nvm content to the current shell meeting. You can do whatever is simpler for you.
When the content is in your PATH, check that nvm was appropriately introduced by composing:
2. Installing Node.js and npm
Presently that the nvm is introduced you can introduce the most recent accessible rendition of Node.js, by composing:
nvm install node
The yield should look something like this:
Downloading and installing node v12.8.1...
Computing checksum with sha256sum
Now using node v12.8.1 (npm v6.10.2)
Creating default alias: default -> node (-> v12.8.1)
When the establishment is finished, check it by printing the Node.js adaptation:
How about we introduce two additional adaptations, the most recent LTS variant and rendition 8.10.0
nvm install --lts
nvm install 8.10.0
To list introduced Node.js variants type:
The yield should look something like this:
default -> node (-> v12.8.1)
node -> stable (-> v12.8.1) (default)
stable -> 12.8 (-> v12.8.1) (default)
iojs -> N/A (default)
unstable -> N/A (default)
lts/* -> lts/dubnium (-> v10.16.3)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.16.1 (-> N/A)
lts/dubnium -> v10.16.3
The passage with a bolt on the privilege (- > v8.10.0) is the Node.js variant utilized in the current shell meeting and the default rendition is set to v12.8.1. Default rendition is the variant that will be dynamic when opening new shells.
You can change the at present dynamic form with:
nvm use 10.16.3
Now using node v10.16.3 (npm v6.9.0)
In the event that you need to change the default Node.js adaptation utilize the accompanying order:
nvm alias default 10.16.3
Install Node.js and npm from the Ubuntu repository
Node.js and npm bundles are accessible from the default Ubuntu 18.04 vaults.
At the hour of composing, the variant remembered for the Ubuntu vaults is v8.10.0 which is the past TLS form.
To introduce nodejs and npm run the accompanying orders:
sudo apt update
sudo apt install nodejs npm
The Node.js executable from the Ubuntu storehouses is named nodejs rather than hub due to a contention with another bundle.
Check the establishment by executing:
Install development tools
To have the option to gather and introduce local additional items from npm you need to introduce the improvement apparatuses.
The accompanying order will introduce all the fundamental bundles including the GCC compilers :
sudo apt install build-essential
In the event that for certain reasons you need to uninstall Node.js and npm bundles, you can utilize the accompanying order:
sudo apt remove nodejs npm
We have indicated you three distinct approaches to introduce Node.js and npm on your Ubuntu 18.04 worker. The strategy you pick relies upon your prerequisites and inclinations. Despite the fact that introducing the bundled rendition from the Ubuntu or NodeSource archive is simpler, the nvm technique gives you greater adaptability for adding and eliminating distinctive Node.js adaptations on a for each client premise.
