@andrewvmail
I did these steps and it worked for me without any problems:

git clone https://github.com/andrewvmail/typeorm-parcel-2-bug.git
cd typeorm-parcel-2-bug
git checkout b96d5651035d04db134837679d4cb9f7ce5cde7b
yarn
yarn add typeorm # it updated typeorm to 0.2.44
yarn start
----------------
yarn run v1.22.17
$ parcel src/index.html
Server running at http://localhost:1234
✨ Built in 1.61s

I also tried this and it worked right away:

git clone https://github.com/andrewvmail/typeorm-parcel-2-bug.git
cd typeorm-parcel-2-bug
yarn
yarn start
----------------
yarn run v1.22.17
$ parcel src/index.html
Server running at http://localhost:1234
✨ Built in 1.61s

Maybe try doing this to fix it on your machine:

rm -rf ./.parcel-cache ./node_modules ./yarn.lock ./package-lock.json
yarn
yarn add typeorm
yarn start

And make sure to update the nodejs version you're using

[andrewvmail]

It passes the parcel build fine but the error comes from the browser console

0.2.43

0.2.25
