That is caused by the React version you are using react@"^17.0.2", while the react-bootstrap-table library is based upon react@"^15.0.0 || ^16.0.0".

Since the difference in version is a major release, you could incur in problems hard to debug, since react could have implemented changes that could have broken the library functionality e.a. reason why npm throws you that error.

At this point, you could either set your project to use react 16 instead of 17 to make sure nothing breaks or you could otherwise keep your version as is and force the library installation as such: npm i react-bootstrap-table --legacy-peer-deps.

If you opt for the second alternative, you know you won't need to use --legacy-peer-deps for new installations as soon as the library maintainers will update the library to work off v.17.
