On a bigger project got the folowing error then parcel is running.
Nothing special, just allot react components in a project. Used scss and css modules

Sorry repo is private and it's not easy reproducible. I will create another issue if it will popup next time. :smile:

Usual it happens then I install additional npm module to project while parcel is running :pray:

Could you try using the last revision on the master branch? I think @davidnagli fixed it in #805.

Can you suggest me how todo so?

@FDiskas You can clone this project and build it yourself by running: git clone [email protected]:parcel-bundler/parcel.git && cd parcel && yarn install && yarn build and then you can use yarn link as described in the second option here.

Looks like it's fixed.
Just keep in mind feels like project build time is 2x slower :stuck_out_tongue_closed_eyes:

And for some reason I got error in first build
" Cannot find module 'uglify-es'"

@FDiskas it should be slower the first time because we are fetching dev dependencies, the next build (even without cache) should be sustainably faster.

@davidnagli any idea for the uglify-es error above?

@fathyb No clue

@FDiskas Can you please provide an example repo so I can try to reproduce?

Fixed in 1.7.0, feel free to reopen if needed.
