Gulp error - Error: Cannot find module 'sigmund'

Question

My Gulp was working fine until I installed browser-sync

npm install browser-sync gulp --save-dev

Then I started to get this error:

Error: Cannot find module 'lru-cache'

Which I solved using this: npm link lru-cache answer from https://github.com/npm/npm/issues/1154

However, now when I try to run gulp I get this new error:

~/Projects/starfeeder ❯ npm install browser-sync gulp --save-dev npm WARN deprecated minimatch@2.0.10: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue npm WARN deprecated node-uuid@1.4.8: Use uuid module instead

fsevents@1.1.2 install /Users/leongaban/Projects/starfeeder/node_modules/fsevents node install

My gulpfile if that helps:

Answer 1

I had this same issue with installing through2 . The project used shrink wrap and had a package-lock.json which caused the a dependencies to break. Once I removed the lock and re-installed, all was good.

Answer 2

Ok so still not sure why I got those errors, but never installing browserSync again.

I had to npm link all my gulp plugins.

That work, but then it broke during the gulp build process.

Instead of doing npm link to everything, included other node modules I've never heard off. I removed browserSync and deleted my node_modules folder and did yarn(npm) install .
