Gulp - Error: cannot find module 'immutable'

The Problem

I’m currently using browser-sync as a gulp dev-dependency for an express.js app. Everything seems to work fine in a local version of this app but when I:

• git clone the repo
• npm install
• npm start or nodemon ./bin/www
• gulp

Running gulp will give me an error that looks related to browser-sync and immutable. Here’s a truncated error (full errors near the end of the issue):

throw err;
      ^
Error: Cannot find module 'immutable'
...
(truncated for length)
...

When I look at the output from install browser-sync by itself, I can see that immutable is installing successfully:

$ npm install browser-sync --save-dev

...
CXX(target)
Release/obj.target/bufferutil/src/bufferutil.o
browser-sync@2.2.2 node_modules/browser-sync
...
├── immutable@3.6.3
...

Attempted Solutions

• I’ve tried deleting my node_modules and re-installing all dependencies with npm install but the error still persists.
• In package.json, tried removing ^ and ~ from dependencies to lock-in versions for npm modules
• (Probably unnecessary but) Rebuilt the app from scratch to see if the error would still persist, and it does. Here’s the repo where I rebuilt it from scratch.

Full Console Output (errors, immutable-related)

The problem was with the immutable lib, which is now fixed. On Sun, 8 Mar 2015 at 06:17, William Huang [e-mail] wrote:

this same error is happening to me on this version, no problems in 2.2.1
