[Solved] Failed to compile. Module not found: Can’t resolve ‘react-router-dom’

After npm start, the browser gives the error:

Failed to compile ./src/components/App/App.js Module not found: Can’t resolve ‘react-router-dom’.

React-router-dom has been added to the dependencies in npm and so has react-router and react.

Project has been created using the create-react-app myapp cmd line. This is runned on a localhost, node server. I have an api and app folder inside my project folder. I have tried various things. Updated manually my package.json inside the app folder, reinstalled react-router-dom, delete the package-lock.json in the app folder and reinitialize it. My api folder holds nothing but node_modules, my api file, route.js, config.js, index.js and also a package.json and package-lock.json. I have tried the npm build command in my app folder. It just creates a ‘build’ folder which holds the same files as my public folder inside my app folder. I also tried running yarn add react-router-dom.

//=========App.js file=========

        <div className="App">
          <Route path='*' component={Header} />

        </div>

    );
  }
}

Solution #1:

I was facing the same issue. The following command will resolve it:

npm install react-router-dom --save

Respondent: Dokme

Solution #2:

This error fix by following steps.
Step.1: npm install –save react-router-dom
Step.2:<script src="https://unpkg.com/react-router-dom/umd/react-router-dom.min.js"></script>
script tag put in public/index.js

Solution #3:

In my case I use Typescript and I needed to install

npm i react-router-dom

AND

npm i @types/react-router-dom

After both installations errors gone.

Solution #4:

For this problem “Module not found: Can’t resolve ‘react-router-dom’
in”

//I found the following solving

// using ES6 modules

import { BrowserRouter, Route, Link } from "react-router-dom";

if it is not working so you have to use the following that I used using CommonJS modules

const BrowserRouter = require("react-router-dom").BrowserRouter;

const Route = require("react-router-dom").Route;

const Link = require("react-router-dom").Link;

Solution #5:

Problem is, your react project does not have a react-router-dom module. You can install and save it with the help of the following command. Just run this command within your project root and everything works fine.

npm install --save react-router-dom

Respondent: Aldomy

Solution #6:

npm i react-router-dom

or

npm install react-router-dom --save

This error occurs because of react-router-dom npm package is missing. install them by using the above cmd.

Respondent: Pranay kumar

Solution #7:

You need to use --save while installing “react-router-dom”. This will ensure that package is stored in package.json file as a dependency and when you try to build the solution on any another machine or on build server, it will take all the dependencies from package.json file and install them.

If you want to install all dependencies on a fresh machine, run the command – npm install

Respondent: Hariharan AR

Solution #8:

Make sure to use npm install –save react-router-dom not npm install –save react-router

Respondent: Naresh Nagpal

Solution #9:

If You have already installed the dependancies , chcked the package.Json file for the react-router-dom dependancy to be sure and it still doesn’t work…
In this case, make sure , you import the packages from ‘react-router-dom’ in the index.js file.

import { BrowserRouter as Router, Switch, Route } from “react-router-dom”

Solution #10:

I resolved the issue when Docker and yarn involved with the error.

The key was to rebuild the Docker image after setting react-router-dom as the dev dependency, just like many answers here detail. The node_modules folder inside docker container needs to update! If your docker-compose.yaml parameter file does not remount node_modules as a volume or otherwise update it, then this answer will not work for your project. Steps:

  1. docker-compose down in project root, or stop the daemon in Docker Desktop
  2. yarn remove react-router-dom
  3. yarn add --dev react-router-dom adds react-router-dom as dev dependency
  4. docker-compose build to rebuild the Docker image
  5. docker-compose up -d for starting the devserver with daemon

In my case I was using Docker, with create-react-app using Typescript template.
I’m using docker-compose to up and down the containers with Docker daemon. If you don’t use docker-compose then you need to modify the container start/stop commands accordingly.

React Router was already installed and functioning correctly (yarn start outside Docker container was not reporting any error). Docker contained frontend server was not functioning correctly.

Solution #11:

npm install react-router-dom 

This command resolves the same issue I faced.
