npm i -g direflow-cli
direflow create
cd <project-folder>
npm install
npm start

Expected behavior
No error

Package Manager:
To install Direflow, I used... npm

Additional context
As I understand @types/babel__traverse: v7+ needs a higher version of typescript (which I have install globally)

ts-node -v 
v10.9.1
tsc -v
Version 5.0.2

But the local node_modules version of tsc is 3.9.10:

npx tsc -v
Version 3.9.10

I have tried chaning a few version of some packages but have got stuck.
