Jest unable to resolve node_modules at the root in Yarn workspace

Jest v22.1.1

To enhance lerna in my project I have enabled yarn workspaces. Since then transformIgnorePatterns does not seem to be able to resolve node_modules at the root.

The same jest config used before switching to yarn workspace:

"jest": {
    "modulePaths": [
        "<rootDir>/src",
        "<rootDir>/node_modules"
      ],
    "setupTestFrameworkScriptFile": "./jest-setup.js",
    "transformIgnorePatterns": [
      "node_modules/(?!lodash-es|react-virtualized|redux-form)"
    ],
    "testPathIgnorePatterns": [
      "/node_modules",
      "/lib/",
      "/es/"
    ],
    "testRegex": "src/.*\\.spec\\.js$",
    "testEnvironment": "jsdom"
  }

This causes Unexpected token import error.

/path/to/project/node_modules/redux-form/es/Field.js:1
    ({"Object.<anonymous>":function(module,exports,require,__dirname,__filename,global,jest){import createField from './createField';
                                                                                             ^^^^^^

    SyntaxError: Unexpected token import

      1 | import React from 'react';
      2 | import PropTypes from 'prop-types';
    > 3 | import ReduxFormField from 'redux-form/es/Field';
      4 | import isEmpty from 'lodash/isEmpty';
      5 | import reduce from 'lodash/reduce';
      6 | import keys from 'lodash/keys';

Is there workaround or proper configuration for allowing jest to play nice in yarn workspaces?

Thanks.

I’m not convinced that symlinking everything is the right solution to what is definitely a real issue. It might be worth reopening this.

Can anyone out together a reproduction?

@SimenB I did a reproduction repo. You can find it here jest-resolve-issue
