How to solve TypeError: environment.teardown is not a function

You shouldn't need to install jest-cli yourself. It should come out of the box.

Try the following:

1. Delete package-lock.json, yarn.lock and node_modules
2. Remove jest from the dependencies in package.json
3. Then do npm install or yarn install.

Add a fresh version of "jest-environment-jsdom" to file "package.json".
