Yarn: When installing with yarn, deps don't work as they would when installing with npm

[jh3y]

_using yarn 0.15.1, OSX 10.10.1 and node 6.3.1_

Might be overlooking something really simple here :confused:

But I may have encountered a possible bug with how dependencies are being installed or the versions that may be being installed.

I'm working on a simple project that makes use of webpack-dev-server and utilizes the hot module reloading feature for live updates in the browser and auto bundling.

I set up a clean simple project, and thought I'd give yarn a spin to pull in the dependencies. HMR wouldn't work at all.

As the source hasn't changed I figured it must be the node_modules. I removed all dependencies and reinstalled with npm. HMR has returned and is working as expected.

To make sure yarn was the issue, I removed all deps again and reinstalled with yarn. Sure enough, HMR ceased to work again.

To reproduce, simply start up a project that uses webpack-dev-server with HMR. Test it using deps installed with yarn and then when the deps are installed using npm.

You'd expect HMR to work regardless of which package manager you use to install dependencies.

Same here, but it happens with browsersync, when start my watch gulp job where is browsersync, the job doesn't works

[jh3y]

Hmm. Maybe a dependency that both browser-sync and webpack-dev-server rely on then that isn't sitting quite right when installed with yarn :cry:

when I tried to migrate my project to yarn, I've had the same issue with webpack-dev-server and react-hot-loader v3.

no idea why 🤔

[jh3y]

Hopefully it's something trivial 🙏

I've encountered a similar issue in the project I'm working on. Slick-carousel works when installed with npm, but fails when installed with yarn.

[altayaydemir]

@tlaak @jh3y have you guys find any solutions? 😅

[jh3y]

Nope 😭

So I'm still not committed to using it.

[tlaak]

It worked with version 0.16, but now that I upgraded to 0.16.1 my project is not even building anymore 😭

[altayaydemir]

😭

[jh3y]

I seem to be having much better luck with everything now 😸

browser-sync has been working fine for me :tada:

Having similar issues with webpack

Using yarn 0.16.1

@jh3y Is this still happening with the latest version of Yarn (v0.24)?

[jh3y]

Sorry for the delayed response 😅

Wanted to make sure and try this out with a fresh clone of the same project that prompted opening the issue, a cache clean etc. Good news! Seems the issue has gone for me :tada: HMR and everything else working as expected. It may have been resolved some time/versions ago.

Happy to close this 👍

@jh3y Great to know! 👍
