In my case, this error came up when I had installed bluebird in the wrong directory.

When I downloaded Bluebird from my home directory

myuser@raspberrypi:~ $ sudo npm install --save bluebird

it is installed in ~/node_modules (and I got some warnings by doing so), and I had to include it by using

var Promise = require('/usr/lib/node_modules/bluebird');


When I install Bluebird from the /usr/lib directory using

myuser@raspberrypi:/usr/lib $ sudo npm install --save bluebird

(no warnings), it is installed in /usr/lib/node_modules (next to the existing npm directory), and I had to include it by using

var Promise = require('/usr/lib/node_modules/bluebird');

So make sure you are aware of where the module is installed and that you refer to it accordingly. In general, here is a description where require looks for modules in nodejs.

In my case the Bluebird folder was called 'bluebird' and i was importing it as 'Bluebird' (with a capital 'B') so i changed the import string to be 'bluebird' (im working on linux).

Hope this helps someone.

I usually use registry to install modules. But I forgot that while downloading hexo-cli. when I run hexo, it responses me 'cannot find bluebird', even though it has been installed.

my solution is:

use registry to install hexo-cli again.

then everything is ok.

I'm having the same issue. It looks as though bluebird is not downloading with its' index.js which would exposes all the functions as a module.

If you cd into node_modules/bluebird you may see that it does exist, but there is no index.js. Since there's no index.js node does not know how to require bluebird.

Here are a few items to try:

  1. If you have a "proxying" npm registry, put a namespace on all packages you pull from that repository, and then edit your npm config pull all packages from the public NPM, unless they are namespaced to pull from your private NPM registry. You can see an example below of how to scope configuration to scopes.

    registry=https://registry.npmjs.org/
@dog:registry=https://npm.dog.com/
@dog:always-auth=true
//npm.dog.com/:_authToken="XXXXXXXXXXXX"
@dog:cafile=/Users/dogboy/.ssh/dogtown.crt

  2. Upgrade NPM versions.

You might need to install the bluebird package locally. Try

npm install --save bluebird
