Install Node.jsFollow this link to the download page on the Node.js website and click the Windows Installer button.
This will start a download of the .msi file.
When that is complete, click on the downloaded file to start the Node.js Setup Wizard. You will be given a series of prompts as you work through the setup wizard.
When you are finished, open a command prompt and execute the following command:
You should see an output similar to this (you may see a different version number based on which one you installed):
NPM (Node.js Package Manager) should have been automatically bundled with your Node.js installation. But you can double-check it with this command:

You now have Node.js installed and it's ready for you to use!
LinuxWe will be using the Node Version Manager (Nvm). And compared to other Node.js installation methods, it has the easiest ways to have multiple versions of Node.js without adding much extra complexity. There will be times when applications need different versions of Node.js to work, so having the flexibility to change that is important and will save you a lot of time.
Before going through these steps, open a new terminal (CTRL+ALT+T) and navigate to the home directory of your machine:
Install/Verify System PackagesFirst, let's update the system packages on your machine:
When that finishes, run the following command to install the build-essential package if you don't already have it: Torrent uploader for mac.
Install Nvm (Node Version Manager)Now we are ready to install the nvm package. Use one of the two (curl or wget) commands below to run the nvmbash script.
At the time of publication, NVM v0.34.0 was the most recent version available. Make sure you check the NVM Github project page to get the latest version and replace the yellow text in the commands below.

curl command:
Or use the wget command:
The bash script clones the nvm repository to ~/.nvm and adds the source line to your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).
Reload the ShellMac Install NpmAfter running the above command, you will receive an output message similar to the following in your terminal:
You can reload the shell by running:
Or simply open a new Terminal window/tab.
Verify the InstallationTo verify that nvm was installed correctly, use this command:
You should see an output with the version of nvm you downloaded.
Now let's install the latest Node.js stable release (replace v10.16.0 with the version you wish to install):
You now have Node.js installed and it's ready for you to use!
