Update to 18.0.0 cause Jest error

[NPM8]

After updating to newest 18.0.0v I got a problem with importing your module:

Test suite failed to run

    Jest encountered an unexpected token

    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:
     • To have some of your "node_modules" files transformed, you can specify a custom "transformIgnorePatterns" in your config.
     • If you need a custom transformation specify a "transform" option in your config.
     • If you simply want to mock your non-JS modules (e.g. binary assets) you can stub them out with the "moduleNameMapper" config option.

    You'll find more details and examples of these config options in the docs:
    https://jestjs.io/docs/en/configuration.html

    Details:

I was trying to change it to react-shadow/styled-component but the same error appears.

Dependecies:

• Jest: 25.2.4
• TypeScript: 3.6.4
• Ts-jest: 25.3.0
• React: 16.13.1

Last running version 17.6.0

Hmm, maybe it's because I removed the CJS build. I didn't really change anything else that would affect the build.

If you're using react-shadow/styled-component then that would become react-shadow/styled-component.cjs

Could you try v18.0.1 please and let me know if this improves the situation?

I tried and it worked, thank you.
