After following the upgrade instructions in the expo article on medium, I ran yarn and got the following warnings and a detox related error which may be relevant, especially since it exited…but I’m not sure how to resolve nor am I sure how/why the detox postinstall script is being run.
Where did you find the information that suggested you simplify your babelrc? I attempted to do what you did but still got the same error, even after deleting my node modules, clearing cache, and re-installing via yarn. I ran yarn add @babel/plugin-transform-react-jsx-source
and found my project working again…
Hmmm, that’s interesting because that broke my config. The fix I described above solved the problem described (for me), but broke my jest tests so further changes had to be made. My babel.config.js file now looks like this…
Thanks for weighing in, Brent. I’m out of my depths here and got some guidance from SWM on my config, but my current config matches your reference with added plugins. Is that good, bad, or ¯\_(ツ)_/¯ in your opinion?
