    import { PatternPrompt, printPatternCaret, printRestoredPatternCaret } from 'jest-watcher';
                            ^^^^^^^^^^^^^^^^^
    SyntaxError: Named export 'printPatternCaret' not found. The requested module 'jest-watcher' is a CommonJS module, which may not support all 
module.exports as named exports.
    CommonJS modules can always be imported via the default export, for example using:

    import pkg from 'jest-watcher';
    const { PatternPrompt, printPatternCaret, printRestoredPatternCaret } = pkg;
