Unexpected token export

Hello, I am back after a 3-month retreat and I am now trying to upgrade my react version within my libraries as suggested by react `16.9.0` using `react-codemod` that use under the hood `jscodeshift`.

This is the project I am currently trying to upgrade: https://github.com/bootstrap-styled/v4

I was using react `16.8.4` and now I'd like to upgrade to react `16.9.0`.

I am running the code-mod with

npx react-codemod rename-unsafe-lifecycles src/**/*.js

Instead of adding `UNSAFE_` before each method, it fails with:

```

It seems that the ES6 files are not readen correctly, am I missing something ?
