If you want to add this to hacktoberfest I can try and submit a PR for the fix.

Go for it

@hipstersmoothie which approach do you prefer?

1. Assume TypeScript is installed on user's machine: add something to the README explaining this assumption and instructions on how to install TS.

2. Add typescript to the package.json?

Add typescript to the package.json?

It's already declared as a dependency: https://github.com/intuit/design-systems-cli/blob/master/package.json#L46

Why is tsc not included?

[adierkens]

Maybe a windows thing? Potentially a npm/node versioning issue?
I just tried a clean clone of the repo and did yarn and yarn start without issue -- but i'm on a macbook. If you're able to diagnose the problem, i'd be curious to know what the underlying issue is.

I would like to work on this issue, I can test the solution in both platforms

I have tested this on Windows 10 Home / Pro, Mac and Linux (Ubuntu), everything is running fine for me, no errors following the indicated steps.

Ok interesting. I'm using a fresh Windows after adding all new hardware. I'm going to start digging into this issue this week.

What happens if you type tsc in your Windows terminal? Also, which Windows terminal are you using? PowerShell? bash?

[jasonrundell]

Just an update that I also can reproduce the same error on my work Mac

[jasonrundell]

@hipstersmoothie can confirm that installing TypeScript locally is what corrects this error.

Can I PR in a README change to help new users make sure they have the pre-requisite software installed as global libraries on their machine before they use the design systems cli?

[pixeleate]

I don't have typescript installed locally, I'm not seeing the error, and it shouldn't be a pre-requisite, one possible solution could be rather that using the tsc alone, you can use the path to local executable ./node_modules/.bin/tsc.

I'm using zsh as my shell interpreter in Mac, Linux and Windows
