Cannot find module node_modules/@testing-library/jest-dom/dist/index.mjs Did you mean to import "lodash/isEqualWith.js

Problem description:

It seems an internal issue with the package itself

Suggested solution:

[edlucas]

Several of the distribution files (in @testing-library/jest-dom/dist) are attempting to import lodash/isEqualWith. This is in addition to importing the correct file lodash/isEqualWidth.js.

An example from index.js:

...
require('lodash/isEqualWith.js');
require('css.escape');
require('lodash/isEqualWith');
...

In my project's node_modules/@testing-library, this occurs in index.js, index.mjs, matchers.mjs, and matchers-12582698.mjs. By commenting out the broken require and import statements, I can eliminate the error and run my tests.

[james-mou]

before the library owners fix this, this is what you can do:

1. open up your package.json file
2. locate any lines that start with @testing-library (I don't care to know which one is broken)
3. remove the caret (^) before the version number ==> this will prevent automatic minor version updates, assuming your test used to work, whatever version you had in there was a good version, stick to it
4. remove dist, node_modules
5. reinstall the dependencies
6. rebuild
7. run tests
8. In a month or two, put the carets back and see if it is still broken, automatic minor version update is a good thing to have in most cases, if it is still broken, curse the library owner and go back to step 1.

My compatriot figured out the quick solution is to use the latest jest-dom.

npm i -D -w=packages/client @testing-library/jest-dom@latest
