I was getting this error when trying to run $node test.js

node:internal/modules/cjs/loader:936

I put this into the same directory as my test.js file.

npm install --save @polkadot/api

this worked for me on Ubuntu.

There are a number of possible causes for this problem, but in my case it was because the parent directory containing my React app was named in the format Next&ReactApps. The presence of the & caused npm to not be able to navigate into the React app's root directory and therefore was throwing these Cannot find module errors.

To fix this, make sure to remove the & from the names of any directories in the path to your applications.

To fix that use the mand "yarn add all" in node.js it would install all prefrence using modules
