npm install could not resolve dependency

After creating a fork, I cloned the repository and ran npm install

The following error was generated:

# npm resolution error report

2020-11-24T14:41:21.984Z

While resolving: rc-tree@4.0.0-beta.2
Found: react@17.0.1
node_modules/react
  peer react@"*" from the root project

Could not resolve dependency:
peer react@"^16.0.0-0" from enzyme-adapter-react-16@1.15.5
node_modules/enzyme-adapter-react-16
  dev enzyme-adapter-react-16@"^1.1.1" from the root project

Fix the upstream dependency conflict, or retry
this command with --force, or --legacy-peer-deps
to accept an incorrect (and potentially broken) dependency resolution.

No file or test is named. Start by running npm install and inspecting the dependency declarations for React and enzyme-adapter-react-16. Done means a clean install completes without the reported peer-dependency resolution error.
