Cannot Resolve Module 'react-dom'

Answer :

Issue is react-dom is not installed, when you hit npm -v react-dom, it gives you the version of npm not react-dom version, you can check that by using npm -v or npm -v react-dom both will give you the same result. You are checking the package version incorrectly.

How to install react and react-dom properly?

Use this to install react and react-dom:

npm install react react-dom --save 

After that, you can check your package.json file, if react and react-dom has been installed correctly, you will find an entry for that.

How to check install package version?

To check all the locally installed packages version:

npm list     

For globally installed packages, use -g also:

npm list -g 

To check the version of any specific package, specify the package name also:

npm list PackageName  For Example =>    npm list react    npm list react-router 

After installation your package.json will look like this:

{   "name": "***",   "version": "1.0.0",   "main": "***",   "scripts": {      ....   },   "repository": {      ....   },   "keywords": [],   "author": "",   "dependencies": {     ....     "react": "^15.4.2",          //react     "react-dom": "^15.4.2",      //react-dom      ....   },   "devDependencies": {      ....   } } 

Latest version of react-dom is : 15.4.2

Reference: https://www.npmjs.com/package/react-dom

In my case I had an alias in my webpack.config.common.js:

 resolve: {     extensions: ['.js', '.jsx'],     alias: {       'react-dom': '@hot-loader/react-dom',     },   }, 

I just removed this line:

'react-dom': '@hot-loader/react-dom', 

and it was fixed.

For anybody reading this that wasn't able to figure it out. I had the same issue which I ended up resolving by installing the "react-router" package which is simply running the following command

npm i react-router-dom --save for a browser app.

npm i react-router-native for a native app.
