JSX element implicitly has type 'any' because no interface 'JSX.IntrinsicElements' exists

# JSX element implicitly has type 'any' because no interface 'JSX.IntrinsicElements' exists

To solve the error "JSX element implicitly has type 'any' because no interface 'JSX.IntrinsicElements' exists", make sure to install the typings for react and restart your IDE.

jsx element implicitly has type any

Open your terminal in your project's root directory (where your package.json file is located) and run the following command:

shell

Copied!
# 👇️ with NPM
npm install --save-dev @types/react@latest @types/react-dom@latest

# 👇️ if you also want to update react and react-dom
npm install react@latest react-dom@latest

# ------------------------------

# 👇️ with YARN
yarn add @types/react@latest @types/react-dom@latest --dev

# 👇️ if you also want to update react and react-dom
yarn add react@latest react-dom@latest

The command will update the versions of your react typings.

Make sure that the jsx option in your tsconfig.json file is set to react-jsx.

tsconfig.json

Copied!
{
  "compilerOptions": {
    // 👇️ make sure it's set to react-jsx
    "jsx": "react-jsx"
    // ... rest
  },
  // ... rest
}

When the jsx option is set to react-jsx, it causes the compiler to emit .js files with the JSX changed to _jsx calls.

Make sure to restart your development server and your IDE if necessary. Your dev server won't pick up the changes until you stop it and re-run the npm start command.

# Delete your node_modules and reinstall your dependencies

If the error is not resolved, try to delete your node_modules and package-lock.json (not package.json) files, re-run npm 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 Linux
rm -rf node_modules
rm -f package-lock.json
rm -f yarn.lock

# 👇️ clean npm cache
npm cache clean --force

# 👇️ install packages
npm install

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

cmd

Copied!
# for Windows
rd /s /q "node_modules"
del package-lock.json
del -f yarn.lock

# 👇️ clean npm cache
npm cache clean --force

# 👇️ install packages
npm install

Make sure to restart your IDE and dev server if the error persists. VSCode often glitches and a reboot solves things sometimes.

If you use VS Code, you can restart your IDE by clicking CTRL + Shift + P or (⌘ + Shift + P on Mac) to open the command palette and type and select Reload Window.

If you still get the error, open your package.json file and make sure it contains the @types/react package in the devDependencies object.

  "dependencies": {
    "react": "^18.0.0",
    "react-dom": "^18.0.0",
  },
  "devDependencies": {
    "@types/react": "^18.0.5",
    "@types/react-dom": "^18.0.1",
  }
}

Or install the latest version of the package:

shell

# 👇️ if you also want to update react and react-dom
npm install react@latest react-dom@latest
