Error: Cannot find module 'body-parser' on clean project with 'body-parser' included in package.json


I just started a clean new project and added ‘body-parser’ to package.json using the ‘Add Package’ button.

I immediately get an error in the logs: Error: Cannot find module 'body-parser'

What am I doing wrong?

I see there’s a new package-lock.json file in the sidebar - is that related?

# package.json

"dependencies": {
    "express": "^4.15.3",
    "body-parser": "^1.17.2"
# server.js

var bodyParser = require('body-parser');
# logs

Error: Cannot find module 'body-parser'

For a quick fix update the scripts section of your package.json to include:

"preinstall": "rm package-lock.json",

The change over to npm 5 for projects seems to be causing issues with module installation. The above will delete the package-lock file allowing install to take place as expected.


hi weavermedia,

you did everything correctly, it was a problem on our end. When we upgraded to Node.js 8.1 we caused this issue. It should be fixed now! Thanks for reporting! :slight_smile:


Thanks @shindakun - good to know :+1:

@etamponi - great, thanks! :rocket:
