Solution

  • The error says that the version of React you are using (17.0.2) is not compatible with react-tilt.

    When looking at the package.json file of react-tilt, you'll see it requires a peerdependency of react@^15.0.0 || ^16.0.0-beta || ^16.0.0.

    NPM enforces correct peerdependencies by default since npm v7. If you realy want to, you can ignore this check and run npm install --save --legacy-peer-deps react-tilt.

    Note that this means there is no guarantee this package will completely work with React 17.
