Duplicate Package Issue

[AdamKyle]

Consider the following package.json:

{
  "name": "toy-box",
  "description": "Toy Box is a simple and efficient DI system based off symfony and other concepts.",
  "version": "0.0.1",
  "license": "MIT",
  "repository": "https://github.com/AdamKyle/Toy-Box",
  "dependencies": {
    "babelify": "*",
    "browserify": "*",
    "gulp": "3.9.0",
    "vinyl-source-stream": "1.1.0"
  },
  "devDependencies": {
    "babel-jest": "*",
    "babel-polyfill": "*",
    "jest-cli": "*"
  },
  "scripts": {
    "test": "jest"
  }
}

When I run: npm test I am confronted with:

> toy-box@0.0.1 test /Users/AdamBalan/Documents/toy-box
> jest

Using Jest CLI v0.9.0, jasmine2, babel-jest

Error: Failed to build DependencyGraph: @providesModule naming collision:
  Duplicate module name: acorn
  Paths: /Users/AdamBalan/Documents/toy-box/node_modules/acorn-globals/node_modules/acorn/package.json collides with /Users/AdamBalan/Documents/toy-box/node_modules/acorn/package.json

This error is caused by a @providesModule declaration with the same name accross two different files.

This is most likely a setup or configuration issue. To resolve a module name collision, change or blacklist one of the offending modules. See http://facebook.github.io/jest/docs/api.html#config-modulepathignorepatterns-array-string
npm ERR! Test failed.  See above for more details.

I do not understand the instructions at: http://facebook.github.io/jest/docs/api.html#config-modulepathignorepatterns-array-string In order to understand what to do.

Is there a fix for this?

I've been having a lot of issues with this today without any luck on understanding the issue. The issue seems related to having the same dependencies in different install paths. For the time being I've downgraded to 0.8.2 to resolve the issue.

Was wondering if this is related to npm v3? I know I've seen issues with auto mocking with the latest version before.

Unfortnelty I was having issues with 0.8.2 So 0.9.0 is the way for me. How ever this acorn stuff needs to be sorted out. Do you know how to black list a package in package.json ??? Is that even possible? Might be a quick fix.

[timReynolds]

@AdamKyle you should be able to add it to the config like so;

  "jest": {
    "scriptPreprocessor": "<rootDir>/jest/preprocessor.js",
    "testRunner": "<rootDir>/node_modules/jest-cli/src/testRunners/jasmine/jasmine2.js",
    "unmockedModulePathPatterns": [
      "react",
      "rect-dom",
      "react-addons-test-utils",
      "enzyme"
    ],
    "modulePathIgnorePatterns": [
      "acorn"
    ]

I'm not sure what the side effects of this are however.

This error is actually generated by node-haste;
https://github.com/facebook/node-haste/blob/971393891676e825916f92cee9815335b3c46f14/src/DependencyGraph/HasteMap.js

From what I can see the logic has always been included in node-haste however

The side effects are the following:

{
  "name": "toy-box",
  "description": "Toy Box is a simple and efficient DI system based off symfony and other concepts.",
  "version": "0.0.1",
  "license": "MIT",
  "repository": "https://github.com/AdamKyle/Toy-Box",
  "dependencies": {
    "babelify": "*",
    "babel-preset-es2015": "*",
    "browserify": "*",
    "gulp": "3.9.0",
    "vinyl-source-stream": "1.1.0"
  },
  "devDependencies": {
    "babel-jest": "*",
    "babel-polyfill": "*",
    "jest-cli": "*"
  },
  "scripts": {
    "test": "jest"
  },
  "jest" : {
    "modulePathIgnorePatterns": [
        "acorn",
        "core-js",
        "isarray",
        "wordwrap",
        "convert-source-map",
        "source-map",
        "which",
        "assert-plus",
        "esprima",
        "path-exists",
        "glob",
        "object-assign",
        "repeating",
        "supports-color",
        "json-stable-stringify"
    ]
  }
}

And yes that list just keeps growing ....

[timReynolds]

Yea I stopped after about 5.

Turns out I made a few other changes to get mine running, see the last commit on this pull request;
timReynolds/react-library-boilerplate#2 timReynolds/react-library-boilerplate#2

Might help.

Well if you are interested, for me at least this finally worked:

{
  "name": "toy-box",
  "description": "Toy Box is a simple and efficient DI system based off symfony and other concepts.",
  "version": "0.0.1",
  "license": "MIT",
  "repository": "https://github.com/AdamKyle/Toy-Box",

  "devDependencies": {

    "babel-polyfill": "*",
    "jest-cli": "*"
  },
  "scripts": {
    "test": "jest"
  },
  "jest" : {
    "modulePathIgnorePatterns": [
        "acorn",
        "core-js",
        "isarray",
        "wordwrap",

        "strip-bom",
        "through2",
        "vinyl",
        "camelcase"
    ]
  }
}

The tests now run and pass ...

Just an update.

I hope this gets fided soon ...

[cpojer]

Thanks for bringing this up, this should most certainly not be a problem and is something that should be fixed somewhere in https://github.com/facebook/node-haste

I'll take a closer look on Monday and fix this.

[cpojer]

Ok, found the issue, it's in node-haste – 2.6.0 was just published a couple hours ago which breaks Jest completely and it's why you are running into this issue unfortunately. This wasn't present in 2.5.0. We'll work on a fix.

[cpojer]

Alright, fix is here: facebookarchive/node-haste#50 – I'll tag 2.6.1 soon, when that's done I'll close this issue and you'll be able to reinstall jest-cli with the node-haste 2.6.1 dependency. I tested @AdamKyle's ToyBox repo with an empty modulePathIgnorePattern and it works as expected again :)

[cpojer]

We are good :) Just re-tried your Toy-Box example and it works with jest 0.9.0 and node-haste 2.6.1. Sorry for the hiccup!

[AdamKyle]

Excellent. Thank you for this fix. :)
