Node.js v19.3.0

Hello,

Same here, I installed Node minutes before, then ran npm install -g @apideck/postman-to-k6. All looked good.
I ran postman-to-k6 -e local.postman_environment.json -s test.postman_collection.json -o k6-script.js and got the same error.
Running with no args at all produces the same behavior.

I hope this helps.

My env :
Windows 10
NodeJS v19.5.0
NPM 9.3.1

Saw the same error with "@apideck/postman-to-k6": "^1.8.7".

For others that see this, the easy workaround is to manually install the prettier package. prettier version 2.8.3 works for me.
npm install -D prettier

install prettier seperately solves this issue

Yes it is a workaround but not a solution.
In like a CI/CD system, you don't want to do this.
I'll try to do a PR to fix it when I have time.

Hi all,
We just released version 1.8.8 of postman-to-k6 with a fix from @BenjaminDls that will solve this issue.
