+This usually means that you are trying to import a file which Jest cannot parse, e.g. it's not plain JavaScript.
+
+By default, if Jest sees a Babel config, it will use that to transform your files, ignoring "node_modules".
+
+Here's what you can do:
+${DOT}To have some of your "node_modules" files transformed, you can specify a custom ${_chalk().default.bold(
+      '"transformIgnorePatterns"'
+    )} in your config.
+${DOT}If you need a custom transformation specify a ${_chalk().default.bold(
+      '"transform"'
+    )} option in your config.
+${DOT}If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the ${_chalk().default.bold(
+      '"moduleNameMapper"'
+    )} config option.
+
+You'll find more details and examples of these config options in the docs:
+${_chalk().default.cyan('https://jestjs.io/docs/en/configuration.html')}
+
+${_chalk().default.bold.red('Details:')}
