What is the current behavior?
Yarn does not publish the output files from webpack (while npm publish still does). I have tried publishing the same node module with npm and yarn, in case of npm the output is successfully exported.

WIth yarn (dist folder missing):

LICENSE README.md main.js package.json
WIth npm
LICENSE README.md dist main.js package.json yarn-error.log yarn.lock

Note that the prepublish command is rm -rf dist && webpack --progress --colors -d and gets executed successfully both by yarn or npm

yarn prepublish v0.23.2
$ rm -rf dist && webpack --progress --colors -d

Confirm, npm pack includes dist folder and yarn pack does not

[cordoval]

is there a workaround besides switching back to npm?

[bestander]

Help us investigate why the folder is not included.
pack.js files is quite small

@BYK. a candidate for HI PRI?

[BYK]

Will investigate.

I think this guys has the bug: https://github.com/yarnpkg/yarn/blob/master/src/util/filter.js#L149

.dist folder is listed in .gitignore so my suspicion is that we use that instead or on top of .npmignore.

This bug seems to have been resolved with the 0.27.0 release (it can be reproduced until then, but not after that) - I'll close this issue, but feel free to reopen it or to ping me if you think this is a mistake.

I seem to be getting this issue on 1.15.2.

Hi sorry for writing into this issue when it's closed, but i can see this issue on v1.22.0. Is there some parameter/switch/... to ignore .gitignore? I'm working with generated code so there's no easy way to modify .gitignore. Thanks

[davidvuong]

I'm also seeing the problem in 1.22.0. My workaround was to add a .npmignore file so yarn stops reading .gitignore.
