Enzyme: Error: Cannot find module "react-dom"

[owencorpening]

I followed all the threads on this, but can't get it working, react-dom is certainly in my package,json, here is what I am typing:

slmbp1510:testBed owencorpening$ mocha-webpack --require setup.js --webpack-config webpack.config-testing.js src/tests/components/Comment-test.js

react-dom is an implicit dependency in order to support [email protected]. Please add the appropriate version to your devDependencies. See https://github.com/airbnb/enzyme#installation
/Users/owencorpening/experiments/testBed/.tmp/mocha-webpack/Comment-test.js:54681
throw e;

[aweary]

Can you share your package.json?

[owencorpening]

BTW just discovered: if I comment out the guts of all the tests, still happens, but if I also comment out the import of enzyme it stops! Here is my package.json:

Can you clear your node_modules and run npm install again to see if that helps?

[owencorpening]

I certainly did that, no help.

[aweary]

For some reason ReactDOM = require('react-dom') is throwing an error for you. It should throw that error in addition to the console.error call, do you see what that error is?

[blainekasten]

Is this project public on github that we can look at?

[aweary]

Also, if you look in your node_modules folder do you see react-dom?

[Duan112358]

sorry about that, I got it at enzyme-example-ava

but the error log that react-dom is an implicit dependency in order to support [email protected] is not correct.

[blainekasten]

I just cloned that repo, installed modules, and ran npm test :\

@Duan112358 maybe try to run npm i again?

[veeracs]

[aweary]

Can you see if react-dom exists in node_modules? What version of Node are you using?

[veeracs]

⚡ npm --version && node --version
2.15.3
v4.2.6

Can you see if react-dom exists in node_modules ?

It doesn't exist.

[lazurey]

I met the same problem and fixed it by npm uninstall react-dom and npm install react-dom --save-dev.

[abdennour]

It seems that you didn't read the README.md of this package where it mentions to install 2 packages :

npm i --save-dev react-addons-test-utils;
npm i --save-dev react-dom;

[sliker]

Any update on this? Same problem here, react-dom reinstalled without success. Thanks.

react-dom exist in node_modules.

[jackson-sandland]

I'm also experiencing this. Why would enzyme not be able to find a dependency that exists in the project?

[ljharb]

It's not enyzme finding anything - enzyme uses require, which unless your tooling breaks it, works in node like every other require. If webpack, for example, is breaking that, then you need to fix your config.

@sliker react-addons-css-transition-group needs to be the identical version as react itself; you have it allowing as low as 0.14.0, but everything else is 0.14.8. Try bumping that?

[sliker]

@ljharb that doesn't work :(
Using ReactTestUtils without enzyme works fine, problem is something with Enzyme and I could not figure out what is it.

Here is my externals, missing something?:

externals: {
                'cheerio': 'window',
                'react-dom': true,
                'react-dom/server': true,
                'react-addons-test-utils': true,
                'react/addons': true,
                'react/lib/ExecutionEnvironment': true,
                'react/lib/ReactContext': true
            }

Edit: The error is different now:
ReferenceError: Can't find variable: react

[blainekasten]

ReferenceError: Can't find variable: react

typically react is imported as React. Is your code looking for a lowercase version when it should be looking for an capitalized version?

[sliker]

typically react is imported as React. Is your code looking for a lowercase version when it should be looking for an capitalized version?

@blainekasten I'm importing correctly: import React from 'react';

Thanks.

[ljharb]

@sliker what's your eslintrc look like?

[sebas5384]

this error continues to happen till today

[ljharb]

I don't think this is relevant any more now that we're on v3.

[thomashagstrom]

I would say it's still relevant @ljharb
Did you not write regression tests for this issue?

[ljharb]

@tomcrusader we have many. What does npm ls print out? react-dom is a peer dep of the v16 adapter, so you have to manually install it as a dep in your own project. Have you?

[thomashagstrom]

Well after reading and re-reading the relevant documentation as well as googling issues with specific versions I sorted this out.

There's a lot of "moving parts" in that all NPM packages have to play nice together. I.E testing, mocking, redux and and your flavour of React. Took me a couple of days (!) to get this right.

Environment:

• OS X High Sierra
• Visual Studio Code

Project platform

• Create React Native App (CRNA)
• Expo 23.0.4
• React 16.0.0-alpha.12
• React-Native 0.50.3

Testing framework:

• Jest ^22.0.6
• Jest-CLI ^22.0.6
• Jest-Enzyme ^4.0.2
• Jest-Expo ^22.0.0
• React-addons-test-utils ^15.6.2
• React-DOM 16.0.0-beta.5

You shouldn't need to use react-addons-test-utils v15 with react 16; and now that react 16 is out, you should upgrade past the alpha.

[felipealfonsog]

it worked out all the mentioned above, but using sudo.

[Navdeep-bains]

It seems that you didn't read the README.md of this package where it mentions to install 2 packages :

npm i --save-dev react-addons-test-utils;
npm i --save-dev react-dom;

these above commands are not in working

[amitntrivedi]

Worked for me after uninstalling and reinstalling. Followed this commandnpm uninstall react-dom and npm install react-dom --save-dev.

I had the same error, I noticed that I had no react-router-dom in the package.json and the solution was install it.
npm install react-router-dom

If it helps someone, in my case I'm using react-hot-loader with their implementation of the React DOM module @hot-loader/react-dom. I fixed the issue just by adding react-dom to my dev dependencies :)
