Npm Command Not Found ? Solution 2021
What Is NPM?
npm is a package manager for the JavaScript programming language. npm, Inc. is a subsidiary of GitHub, that provides hosting for software development and version control with the usage of Git. npm is the default package manager for the JavaScript runtime environment Node.js
please install Node Package Manager in your system. This requires you to install Node.js
To see if NPM is installed, type npm -v in Terminal. This should print the version number so you’ll see something like this 1.4.
The npm file should be in /usr/local/bin/npm
. If it’s not there, install node.js again with the package on their nodejs. This worked in my case.

how to update npm packages
Updating local packages
We recommend regularly updating the local packages your project depends on to improve your code as improvements to its dependencies are made.
-
Navigate to the root directory of your project and ensure it contains a
package.json
file:cd /path/to/project
In your project root directory, run the
update
command:npm update
-
To test the update, run the
outdated
command. There should not be any output.npm outdated
Updating globally-installed packages
-
Note: If you are using npm version 2.6.0 or less, run this script to update all outdated global packages.
However, please consider upgrading to the latest version of npm:
npm install npm@latest -g
how to uninstall npm package
To uninstall a package you have previously installed locally (using npm install <package-name>
in the node_modules
folder, run
npm uninstall <package-name>
from the project root folder (the folder that contains the node_modules folder).
Using the -S
flag, or --save
, this operation will also remove the reference in the package.json
file.
If the package was a development dependency, listed in the devDependencies of the package.json
file, you must use the -D
/ --save-dev
flag to remove it from the file:
npm uninstall -S <package-name> npm uninstall -D <package-name>
If the package is installed globally, you need to add the -g
/ --global
flag:
npm uninstall -g <package-name>
for example:
npm uninstall -g webpack
and you can run this command from anywhere you want on your system because the folder where you currently are does not matter.

what does npm init do?
Most developers run npm init right after creating and navigating into a new project. It makes sense to npm init at the start of the project because we use npm to download dependencies. Once we npm init , we can begin downloading (and saving) our dependencies. For most projects, this workflow works.
