I am getting below error when installing particle.js in my React App:

  • You need to downgrade your React version to version 16 because *react-particle-js* requires React V16 as its [peer-dependency](https://github.com/Wufe/react-particles-js/blob/84856a2ce47e41ace6dd6aaabf1189dfd830ca84/package.json#L41) – Ajeet Shah Mar 01 '21 at 10:31
  • Or you can try [--legacy-peer-deps](https://stackoverflow.com/q/66020820/2873538) option. – Ajeet Shah Mar 01 '21 at 10:37
  • Or you can use `react-tsparticles` [package](https://www.npmjs.com/package/react-tsparticles) (same core library, supports React 17) – Caelan Mar 01 '21 at 22:39
  • thank you I have installed react version 17 + react version 16.8.4 and it works – gydee Mar 03 '21 at 10:42
