Cannot find module 'react' Error in TypeScript [Solved]

# Cannot find module 'react' Error in TypeScript

To solve the "Cannot find module react or its corresponding typedeclarations" error, install the module and its type definitions by running thecommands npm install react and npm i --save-dev @types/react.

Make sure to install the react module and its type definitions by opening yourterminal in your project's root directory and running the following commands.

shell

Copied!

# 👇️ with NPMnpm install react react-domnpm install --save-dev @types/react @types/react-dom# ---------------------------------------------------# 👇️ with YARNyarn add react react-domyarn add @types/react @types/react-dom --dev

Now you should be able to import the reactlibrary with the following line of code.

index.ts

Copied!
import React from 'react';console.log(React);

This should fix the error and now TypeScript should be able to find the type definitions for the react library.

# Set `moduleResolution` to `node` in `tsconfig.json`

If that doesn't help, try setting moduleResolution to node in yourtsconfig.json file.

tsconfig.json

Copied!
{ "compilerOptions": { "moduleResolution": "node", // 👇️ ... rest }}

You can read more about classic vs node module resolution in theTypeScript docs.

# Delete your node_modules and reinstall your dependencies

If the error is not resolved, try to delete your node_modules andpackage-lock.json files, re-runnpm install and restart your IDE.

If you are on macOS or Linux, issue the following commands in bash or zsh.

shell

Copied!

# for macOS and Linuxrm -rf node_modulesrm -f package-lock.jsonrm -f yarn.lock# 👇️ clean npm cachenpm cache clean --force# 👇️ install packagesnpm install

If you are on Windows, issue the following commands in CMD.

cmd

Copied!

# for Windowsrd /s /q "node_modules"del package-lock.jsondel -f yarn.lock# 👇️ clean npm cachenpm cache clean --force# 👇️ install packagesnpm install

Make sure to restart your IDE anddevelopment server if the error persists.

You can also try to install the latest version of React and its typings.

shell

Copied!

# 👇️ with NPMnpm install react@latest react-dom@latestnpm install --save-dev @types/react@latest @types/react-dom@latest# ---------------------------------------------------# 👇️ with YARNyarn add react@latest react-dom@latestyarn add @types/react@latest @types/react-dom@latest --dev

# Make sure you have the react-related packages installed

If you still get the error, open your package.json file and make sure itcontains the react package in the dependencies object.

package.json

Copied!
{ "dependencies": { "react": "^18.2.0", "react-dom": "^18.2.0", }, "devDependencies": { "@types/react": "^18.0.27", "@types/react-dom": "^18.0.10" }}

The react and react-dom modules have to be in your dependencies object.

The @types/react and @types/react-dom packages have to be in yourdevDependencies object.

You can try to manually add the lines and re-run npm install.

shell

Copied!

npm install

Or install the latest version of the packages:

shell

Copied!
