I wanted to post my process which normally fixes these issues for me.
First off – the first thing you should always try first is to delete your node_modules folder and clean the cache:
# Once you've deleted your node_modules folder in your project.. npm cache clean npm install
I usually uninstall Node from my system and reinstall the latest version, as well as delete the node_modules package from the project which I’m having the troubles with.
- Uninstall Node.js in your programs
- Delete c://users//username//AppData/Roaming//npm
- Delete c://users//username//AppData/Roaming//npm-cache
- Open your environment variables and delete all references to node.js / npm
Once everything is uninstalled and the machine is clean, go and and download and reinstall node. Keep in mind you’ll need to reinstall all global node packages like gulp, bower – etc.
You can verify your versions of node.js:
# Check your node.js version node -v # Check your npm version npm -v
