Got error in Node JS when it downgrade node version or npm version

Question

My application in windows machine does run only the node version of v6.11.0 and NPM is 3.11.11.

Now, my node version and NPM have been upgraded. I am not able to download the node version and NPM version. Current version of node is v10.14.1 and npm is 5.5.1

When I tried to downgrade, I am facing the below error.

npm install -g [email protected]
npm install -g [email protected]

Below error

npm WARN npm npm does not support Node.js v10.14.1

I installed the Node v10.14.1 and encountered the same error while installing a package.

I tried to uninstall and reinstall; but did not solve the problem. The installation of Node.js did not update/upgrade the "npm" version.

Then I followed below steps to fix the problem.

Go to "C:\Users\\AppData\Roaming" and delete the "npm" folder.
Repair the Node.js installation (you could also reinstall it)

I hope this will help to resolve the issue.

npm i -g npm@add version which you need to rollback.

eg: npm i -g [email protected]

Then check your version:

npm -v

i - install g - globally
