+
+Jest failed to parse a file. This happens e.g. when your code or its dependencies use non-standard JavaScript syntax, or when Jest is not configured to support such syntax.
+
+Out of the box Jest supports Babel, which will be used to transform your files into valid JS based on your Babel configuration.
+
+By default "node_modules" folder is ignored by transformers.
+
+Here's what you can do:
+${DOT}If you are trying to use ECMAScript Modules, see ${_chalk().default.underline(
+    'https://jestjs.io/docs/ecmascript-modules'
+  )} for how to enable it.
+${DOT}If you are trying to use TypeScript, see ${_chalk().default.underline(
+    'https://jestjs.io/docs/getting-started#using-typescript'
+  )}
+${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/configuration')}
+For information about custom transformations, see:
+${_chalk().default.cyan('https://jestjs.io/docs/code-transformation')}

+${_chalk().default.bold.red('Details:')}
