#### npm install fails on NPM 7

If you are using `npm 7` (you can find out the version by typing `npm -v` in your terminal), then you may get the following error when you run `npm install`:

```bash
npm ERR! Could not resolve dependency:
npm ERR! peer react@"^16.14.0" from react-test-renderer@16.14.0
npm ERR! node_modules/enzyme-adapter-react-16/node_modules/react-test-renderer

npm ERR! Fix the upstream dependency conflict, or retry

```

To fix this problem, update your package.json and include the `react-test-renderer` package and use the exact same version you've used for your `react` package.
