javascript - npm install getting Cannot read property 'name' of null error

Not too sure what is causing this error as npm install works fine on other puters.

NPM and Node versions:

C:\Users\Work>npm -v

I have started to get the same error as you. Same npa.js throwing the TypeError. Based on what I see I assume you're using Laravel as well. Not sure what is going on because I didn't actually make any changes to my NPM packages.json. I am using node v16.13.0 and npm v8.1.0 so it doesn't seem to be related to versions – ComputerLocus Commented Feb 12, 2022 at 20:56
Hey, try removing npm from dependencies then 1. delete package-lock.json and node module folder 2. run npm install again. – Sakshi Mahajan Commented Feb 14, 2022 at 10:23

This error is occurring with the npm version that you are using: v8.3.2 and the way that you passing the version of the module "tailwindcss": "npm:@tailwindcss/postcss7-pat@^2.0.2"

If you remove this library will see that the error will stop to happen.

To solve this you can change the tailwindcss version to ^2.0.1-pat:

"tailwindcss": "^2.0.1-pat"

Or upgrade or downgrade your npm version:

Try to downgrade your node.js and npm version for other lts version like the lts/fermium (node v14.19.0, npm v6.14.16) or upgrade to the stable version (node v17.5.0, npm v8.4.1)

Also, the remended version for the npm with the node version v14.16.1 is the is 6.14.12 and not 8.3.2 as we can see in the releases table.

When you change the npm version you will need:

Delete the node_modules directory and package-lock.json file.
Reinstall the modules using npm install
