Jest test suite - Babel Error

// sh
FAIL  jestTests/app.test.js
  ● Test suite failed to run

    Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @ba
bel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace
 of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is call
ing Babel. (While processing preset: "/Users/Stephen/Documents/_coding/matilda/node_modules/@babel/preset-env/lib
