Hi everyone! No need for more "happens to me" comments since we have a fairly good understanding of why and how this happens. We'll try to get at this ASAP, and at least suppress the warning since it is not useful to you, as the users.

Apologies for the trouble. In the meantime, if anyone is interested in giving this a shot until we do, feel free to ping me here or on Discord and I'd be happy to guide you!

Scheduled to be released in 0.28 - either revert the check or find out why a folder is copied twice

FWIW, I've also experienced this using --nightly with the install script

Thanks, I'll investigate + convert the check into a warning

bestander picture bestander on 30 Jun 2017

Pinning to 0.27.3 works for me.

cibernox picture cibernox on 30 Jun 2017

Yeah, it is only in master right now

bestander picture bestander on 30 Jun 2017

The problem is in bundledDependencies.
Sending a PR to make the issues non breaking installation

The bug is mitigated, the PRI can be lowered

The bug is mitigated, the PRI can be lowered

I think we should keep this high-prio and fix the underlying issue in 1.0

Still seeing these warnings on yarn install npm using v0.28.4.

Still happening in v1.0.1.

not sure it it's a proper solution, remove yarn.lock then re-run yarn worked for me :)

I am getting these warnings even with the list command:

Why would copy be required for listing globally installed modules?

sudo-suhas picture sudo-suhas on 14 Sep 2017

@sudo-suhas, that is a separate bug.
Afaik yarn global list actually runs install command :(

@BYK Hi, I'm experiencing this issue also. Perhaps, we could have a roll-up message for each immediate dependency that has duplicate file copies, something like:

"warning The module "[email protected]" has case-insensitive files that shouldn't be copied twice. Please run yarn with --verbose for a complete listing."

At least this would reduce the amount of warning text that hits the screen during install. The warning comes from:

https://github.com/yarnpkg/yarn/blob/0ee1c55fd55f3863a7544e40a774162764d29536/src/util/fs.js#L225

Maybe an approach would be to keep a Map of each module that encounters this issue, and report the above message only when it's first seen.

Thanks for your time and attention on this matter!

kriswill picture kriswill on 18 Sep 2017

There is a flaw in the logic how folders are copied, probably because it all happens recursively and in parallel.
It should not affect end users very much (files won't be copied twice) but I did not want the developers to loose this issue out of sight because this flaw may cause unexpected behavior in the future.

If anyone has some time to go deep into the reasons why it is happening and provide a fix that would be so awesome.

bestander picture bestander on 18 Sep 2017

@bestander I briefly looked at this a few days ago. Looks like it is due to us neglecting bundledDependencies completely. I think this is related to #4417

BYK picture BYK on 18 Sep 2017

Why is this warning showing up at all if I may ask? Is this something package developers can do anything about at all? Let alone consumers of packages? Isn't it some internal "how yarn copies stuff" issue?

I'm literally being spammed with this error message with one particular repository generating about 150 of these warnings during a single install.

adamreisnz picture adamreisnz on 23 Sep 2017

I hear you @adamreisnz, thanks for sharing the frustration. I'll try to look into it this week but at the very least, we should just remove the warning.

BYK picture BYK on 23 Sep 2017

@adamreisnz can you share the package you are experiencing this issue with?

BYK picture BYK on 23 Sep 2017

I know this is 99% related to how bundledDependencies are handled but just want to make sure your case is also covered by that.

BYK picture BYK on 23 Sep 2017

@BYK an example repo to reproduce is here: https://github.com/clintmod/koa-neo4j-secure-rest-api
the fsevents package (refd by nodemon) is causing the warnings via node-pre-gyp that look like:

The case-insensitive file /Users/clint/code/github/clintmod/koa-neo4j-secure-rest-api/node_modules/fsevents/node_modules/node-pre-gyp/lib/reveal.js shouldn't be copied twice in one bulk copy

steps to repeatedly repro are:
rm -rf ./node_modules && yarn

where yarn version = 1.0.2

@BYK thanks for looking into it. The following package.json was what was causing so many warnings about bulk copies for us (but in reality, since upgrading to yarn 1.x.x, any package/site I work on generates these warnings);

Just my two cents here..not sure whether it's helpful. I started seeing this too today, but in my case, it's a module I installed from filesystem (yarn add file:...) and: I'm on Windows.
Have you guys replicated the issue on non-windows systems? Because.. I usually rest assured such issues are just because of Windows :)

I also see this error with the yargs lib. Doing a yarn list yargs reveals that my project actually has four different versions (and the same version twice?)

tim-soft picture tim-soft on 25 Sep 2017

@tim-soft I guess it's correct to see the same version twice because apparently, the main dependency is @3.10.0 and any package that requires a version different from that has to include it in its own ./node_modules. Happens to be twice.

Did a yarn install today and this showed up. It also indicated I should upgrade yarn to 1.1.0, but I get the same output.

Hi everyone! No need for more "happens to me" comments since we have a fairly good understanding of why and how this happens. We'll try to get at this ASAP, and at least suppress the warning since it is not useful to you, as the users.

Apologies for the trouble. In the meantime, if anyone is interested in giving this a shot until we do, feel free to ping me here or on Discord and I'd be happy to guide you!

I'd just like to point out that this is still very much an issue. Every yarn version thereafter [email protected] seems to barf when there is a dependency that specifies any bundledDependencies.

I'm a bit concerned with why [email protected] was released with this issue outstanding.

There's a possibly related issue (or perhaps root cause):

As of 1.3.2 bundled dependencies are double installed. Once from the bundle, in the bundling module's node_modules and again into the top level project's node_modules. The latter are the only parts referenced in the lock file.

If the resolver ends up deciding one of those deps currently being installed at the top level has to be hoisted, I think that would cause the problems described here (with multiple of the same destination).

npm, fwiw, records all of the bundled modules in its lockfile, with annotations so it knows that they're sourced from the bundling tarball, not from stand alone downloads.

Thanks for looking into this for us, @iarna, very much appreciated!

@iarna the issue is the complete neglect of bundledDependencies in Yarn right now. Since they are already shipped inside the tarball they get "installed" when we extract the tarball. They get "reinstalled" when yarn simply carries on normal operations by resolving and installing the package's dependencies.

I think blacklisting any node_modules during linking would at least make the behavior sane and we can safely say "we do not support bundledDependencies at the moment". After that, we can start devising a proper solution which may include marking bundledDependencies and excluding them from global resolution.
