Running on MacOS node version: v4.2.3
Running on Amazon Linux node version: v6.0.0-pre

temporal fix:
rm -rf /node_modules/mongoose/node_modules/mogodb npm install --prefix ./node_modules/mongoose/ mongodb@2.1.6 --save

[yvan]

yeah this is happening to me as well.

@chelinho139: are you sure you don't mean?

(missing 'n' in mongodb)

rm -rf /node_modules/mongoose/node_modules/mongodb

and then

npm install --prefix ./node_modules/mongoose/ mongodb@2.1.6 --save

@yvan

rm -rf /node_modules/mongoose/node_modules/mongodb npm install --prefix ./node_modules/mongoose/ mongodb@2.1.6 --save

Your soultion don't work exactly like this, what i did and it works is:

1. Remove mongoose and mongodb.
2. Install mongoose.
3. Go to ./node-modules/mongoose and open package.json, change mongodb version to 2.1.6
4. Run npm install in mongoose root.

Alternatively I found installing the Kerberos module helped to fix this.
npm install kerberos --save

None of this ended up helping I ran into other issues. I exhausted most online threads and my patience. I went from monk to mongoose, back to monk, and now i'm just using the native node.js mongo driver for my little scripts. Monk and mongoose were working so well just a few months ago ...

The root cause is within https://www.npmjs.com/package/mongodb-core which prints out the error when the kerberos (optional) dependency is not installed. (mongodb-js/mongodb-core@c130871)

mongodb-core has removed the printing out the error message in version 1.3.1
mongodb upgrades its dependency on mongodb-core in version 2.1.6
mongoose in the latest releases version 4.4.2 is using mongodb version 2.1.5

The error message is just annoying and should not have any impact on using mongoose. If you require the Kerberos feature then you probably already had it installed or were possibly depending on npm to install peer dependencies for you. As @domjtalbot noted you can install kerberos or wait for the next release of mongoose that upgrades to mongodb 2.1.6+

Already resolved in master (8fe1fa3)
