Are you seeing the error “Cannot find module ‘react’ or its corresponding type declarations” when trying to use the React library in a TypeScript project?” This error occurs when the React library and its type definitions are not installed in your project.

How to Fix the Error “Cannot find module ‘react’ Error in TypeScript”?

To fix this error, open your terminal in the root directory of your project and run the following commands:

Additional Troubleshooting Steps for Error “Cannot find module ‘react’ Error in TypeScript”

It’s important to note that the error “Cannot find module ‘react’ or its corresponding type declarations” can also occur if you have a typo in your import statement, or if you are trying to import a module that doesn’t exist. In this case, double-check your import statement and make sure it is correct.

You can also try using the import statement with a relative path to the module, rather than using the module name. For example, instead of import React from ‘react’, you could try using import React from ‘./node_modules/react’. This can be helpful if you have multiple versions of a module installed in your project, or if you have a custom module resolution set up.

If the error persists after installing the React library and its type definitions, try the following additional troubleshooting steps:

Set the “moduleResolution” option to “node” in your tsconfig.json file:

{
  "compilerOptions": {
    "moduleResolution": "node",
    // ... other options
  }
}

Delete your node_modules and package-lock.json files, run npm install, and restart your IDE:

rm -rf node_modules package-lock.json
npm install

To fix the “Cannot find module ‘react’ or its corresponding type declarations” error in TypeScript, make sure to install the React library and its type definitions, and consider setting the “moduleResolution” option to “node” in your tsconfig.json file.
