Unable to resolve module fs

[helgahjartar]

Hello,

I'm getting the following error when I try to run the metro bundler after adding react-native-config-node to my project:

error: Error: Unable to resolve module fs from ../node_modules/react-native-config-node/index.js: fs could not be found within the project or in these directories: node_modules

The suggested solution is removing node_modules, re-installing and clearing the cache, which I've tried and it hasn't worked.
Any ideas?
