Cannot find module 'react-addons-test-utils' from 'react-compat.js'

[tugorez]

Hi guys, thank you for such a nice library :)

I just created a react-native project today but when I try to run a test, this error message appears

Cannot find module 'react-addons-test-utils' from 'react-compat.js'

I believe this is caused by React 15.5 changing the location of the react-test-utils to react-dom/test-utils. Meanwhile, enzyme's package.json file allows for 15.5 to be used.

Edit: If I am correct, #637 might be tangentially related.

[ljharb]

Also, see #892 and #876.

and i am getting error Error: Cannot find module 'react-dom/test-utils'

Any pointer is highly appreciated.

[ljharb]

Bump react-dom to 0.14.8? All the react-* things need to be the same version.

[matijastampfel]

I find solution. You are missing npm package. Go to cmd and type yarn add react-addons-test-utils Hope it helps. ;)

[ljharb]

@matijastampfel we're not missing it. It's part of the instructions for React < 15.5.

[rosskevin]

I just bumped into this and seeing it with React > 15.5

    "enzyme": "^2.8.2",
    "react": "^15.6.0",
    "react-a11y": "^0.3.4",
    "react-addons-perf": "^15.4.2",
    "react-docgen": "^3.0.0-beta4",
    "react-dom": "^15.6.0",
    "react-test-renderer": "^15.5.4",

yarn list react-dom                                                                                                                                                                                 update-dependencies ✭
yarn list v0.24.6
└─ react-dom@15.6.0

[ljharb]

@rosskevin just to confirm; even if you update react-test-renderer to 15.6 (since, generally, all react-* packages always need to be on the same minor), you still see the problem?

[rosskevin]

@ljharb that was the most current as of 18 hours ago. Confirmed fixed now with updated packages released ~14 hours ago:

 react                ^15.6.0  →  ^15.6.1 
 react-dom            ^15.6.0  →  ^15.6.1 
 react-test-renderer  ^15.5.4  →  ^15.6.1 

[ljharb]

Thanks, looks like this is resolved (and that the react team may need to coordinate more timely release of their packages ;-) )

[ljharb]

(Happy to reopen if this problem is continuing to occur for anyone; also, filing a new issue would be great too!)
