Let me show you the right way of npm installation in windows.


How to install node on Windows 10


→ Step1: Download Node Js


Download Node.js software from this website. The most recent LTS version is node-v14.15.3. Package npm is in-built. You don’t have to install it separately. If you own an older version of windows, select the 32-bit version of the node.js installer. Else you can choose 64-bit in all other cases.

→ Step2- Install Node.js and npm


Double click on the installer node-v14.15.3-x64.msi and then follow the steps.


  • Step2.1 – Accept all the terms in the license agreement and click next.
  • Step2.2 – Select the folder for node.js installation. Default location of node.js is “C:\Program Files\nodejs\“. It will be better if you keep it default.
  • Step2.3 – Select node.js features. I will suggest you leave it by default. Make a note, npm (node package manager) will be there as part of this download. You don’t need to install it in a seperate way.
  • Step2.4 – Choose an optional tool (chocolatey) to compile native modules, if necessary. I can suggest you keep it unchecked.
  • Step2.5 – Click install.

→ Step 3 – Check the npm and node Js versions.


  1. Check the node js version.
  2. Then check npm (node package manager) version.
  3. Now you will not get any “npm command not found error” in Windows 10.

How you can check the npm path variable in Ubuntu 20.04


You need to make sure, that npm is already installed, if not, follow how to install node JS and npm in Ubuntu 20.04 steps in this article.

Step 1 Check a default path for npm command.

Step 2 – Check /etc/environment file for npm path.

Step 3 Edit /etc/environment file and add npm path.

Add npm path till bin folder at the end of environment file separated by a colon “:”. Then save and exit from file. Npm path should be within quotes ” “.

For example, /usr/bin in my case.

Reload environment file for changes.

How to check the npm path variable in Windows 10


First, you have to check whether node js and npm are installed in Windows 10 or not. If it’s already installed you need to follow these steps:-


  1. Step 1 – Search for the environment variable.

  4. Step 1.3 – Select “Path” and then click on Edit.

If npm variable path doesn’t exist there, Click New > Add npm variable path “C:\Program Files\nodejs” > Click OK.

(Please take note that you need to replace the default “C:\Program Files\nodejs” with your custom target Folder. In case you have selected another different folder during the installation process.)

Click OK two times to close all open dialogue boxes.
