creating my first repo have a problem

[arilishu]

i am trying to install dbos on my mac, I am following this steps:
https://docs.dbos.dev/quickstart
Everything works great until I hit this command:

dbos init

I get this error:

Any idea what is wrong?

Thanks!

Try pip install "psycopg[binary]" in your virtual env.

Hi there @arilishu sorry about the trouble!

Is there anything special about your environment? What OS are you using?

[arilishu]

I am on a Mac. Nothing special on my end.

@arilishu thanks.
Looks like you're missing some Postgres drivers. It's not clear why. have you tried what @boltomli suggested above?

Hello! Here are two potential steps you can try:

1. Looks like your machine doesn't have the libpq library. Try to install it through brew install libpq.
2. Try to install the binary version as @boltomli suggested above. However, the binary version might not be available on certain macOS versions and m1/m2 silicons.

Thank you for reporting this issue! We'll improve the quickstart installation guide.
