How to use --modules-folder flag?

[borela]

Sorry if this was asked before but I couldn't find an example in the documentation/google search.

Does this flag mean that I could have a "vendor" directory instead of "node_modules"? How to use it?
I tried something like yarn install --modules-folder ./vendor/node_modules and it just installed the modules in ./node_modules.

Please mention your node.js, yarn and operating system version.
Windows 7
yarn 0.16.1

There's a bug actually. Make sure you delete the node_modules folder, then it should work fine.
If node_modules is present then it would always say Already up-to-date.

This thing isn't documented on the website. I'll do it within next couple of days.
Meanwhile, you can refer this.

Thank you @dhruvdutt it worked. Is there any way to set the new modules folder as default?

[Promixius]

a way to set the default module path would be favorable as running yarn upgrade later when a package has an update will again pull it into node_modules instead of ./vendor/node_modules

[dhruvdutt]

@Promixius I was thinking about the same. To make a configurable file or something for this purpose.

any way to recover branch clean-workflow from #281?

I would be able to bisect this further if you push clean-workflow again @kittens

result of further bisecting:

There are only 'skip'ped commits left to test.
The first bad commit could be any of:
f5f77ed
61890e9
ec7b1e5
f13537f
We cannot bisect more!

After working around skipped commits I found this to be the trouble maker:

Add integrity hash check to `kpm install`

If I run yarn install --production --modules-folder production to have a folder that can be deployed to the production environment and I then run yarn install to get a local node_modules folder to run the build with (in this particular order because of the bug mentioned here and addressed by the PR above), yarn removes all modules from the folder production. This can be worked around by renaming the folder before the second run of yarn install, but I would prefer if yarn would just ignore that folder as long as it isn't specified again using --modules-folder.
Could that be changed or is the current implementation on purpose and required?

IMO --modules-folder should be available on all commands.
Simple use case:

yarn install --modules-folder tmp/modules
yarn run [command] --modules-folder tmp/modules

specifying in package.json would be amazing. Any ETA on this ?
