Yarn is not deterministic when adding a new package to an existing project vs. a clean install

[wereHamster]

If you start with a clean create-react-app (v1.2.1) project, yarn installs babel-loader but its dependency babel-core is moved to the top-level node_modules so that it can be shared by all packages.

When you then add the two packages react-svg-loader and svg-react-loader yarn keeps the top-level babel-core, so that babel-loader continues to use that version (v6.22.1).

However when you remove all dependencies (rm -rf node_modules) and let yarn install everything afresh, it will install babel-core v6.13.2 as a private dependency of babel-loader, which is incompatible with other packages.

Steps to reproduce

$ ceate-react-app yarn-bug
$ cd yarn-bug
$ yarn build # works
$ yarn add react-svg-loader svg-react-loader
$ yarn build # works, too
$ rm -rf node_modules
$ yarn
$ yarn build # fails

That sucks, we need to fix it, thanks for the steps

What is the error message?

Success! Created yarn-bug at /Users/tomc/yarn-bug
Inside that directory, you can run several commands:

  yarn start
    Starts the development server.

  yarn run build
    Bundles the app into static files for production.

  yarn test
    Starts the test runner.

  yarn run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd yarn-bug
  yarn start

Happy hacking!

error Command failed with exit code 1.

[bestander]

I think I know the reason.
There is a step during resolution in install command when Yarn merges semver compatible dependencies and installs the highest compatible one.
This step is not run during add command for some reason, which is a bug.

The error you see is probably caused by a breaking change in a library (babel-loader?).
PR and help in debugging would be welcome

[roman-holovin]

I have a similar problem with my project. https://github.com/dantix/waterly/tree/eslint-airbnb
If I do a clean install, eslint is not working properly. If I install eslint 3.15.0 first, then update it to the 3.19.0 - it will work properly.

I've made a diff of file tree and there is a difference in how eslint dependency is included in modules.
In my case, after clean install eslint-config-airbnb has empty node_modules directory, after downgrade and upgrade eslint, it has eslint in local node_modules with 3.16.1 version.

Repro:

cd /tmp
git clone git@github.com:dantix/waterly.git
cd waterly
git checkout eslint-airbnb
yarn
yarn lint # there should be a lot of errors
yarn add eslint@3.15.0
yarn add eslint@3.19.0
yarn lint # there should be a handful of warnings

[bestander]

Thanks for repro steps

@bestander maybe I found why it is not deterministic: when we prepare the requests (https://github.com/yarnpkg/yarn/blob/master/src/cli/commands/add.js#L39) for the command yarn add <mypackage> we push errounously <mypackage> instead we should push <mypackage>@<version> like we do in the install command. I tried to fix, but it doesn't work as expected O.o I prefer to share the information, so maybe you can fix it better.

[bestander]

Thanks.
The trick is that Yarn replaces with maypackage@version here https://github.com/yarnpkg/yarn/blob/master/src/cli/commands/add.js#L90 at resolution step.

IIRC here https://github.com/yarnpkg/yarn/blob/master/src/package-request.js#L245 the optimization of yarn.lock happens and unused resolutions are getting left out.
Would be good to debug and see why it fails for add command.

[blexrob]

When running yarn check after the yarn command from the repro steps, I immediately got some errors. This was caused by the package resolver resolving patterns to different versions based on the order of package version resolve answers. I have filed issue #3466 for that.

[arcanis]

Should be fixed in 0.27.2 👍
