Improved b.c. support for nix-build · digitallyinduced/ihp-boilerplate@eebbda8

CSchank · 2023-06-05T20:58:47Z

@mpscholten this broke new IHP projects for us on macOS and Codespaces. Is this a mistake? Or is something not configured right on our end to support this?

mpscholten · 2023-06-05T21:01:17Z

Can you share the error message? This change is in preparation for the upcoming IHP v1.1.0 release

A few things seem to go wrong, including direnv allow not working:

And, when trying to run nix-shell:

This seems to be caused by a missing flake.lock. Just pushed this via 177a78a Now ihp-new test work again locally

CSchank · 2023-06-05T23:46:17Z

I'll try it out, thank you!

CSchank · 2023-06-06T00:15:58Z

I'm still getting this when trying to run it in Codespaces (the old default.nix without flake still works perfectly). And this version does appear to work in macOS. Any ideas?

Nevermind, I think we have to retool our postCreateCommand script. I'll play with it and get back to you.

mpscholten · 2023-06-06T06:22:32Z

Ok, let me know in case I can help in any way

CSchank · 2023-06-06T18:59:21Z

Hi Marc! Still having the issue above in Codespaces. In a plain Ubuntu installation using Nix directly, the server compiles all the way to Main but then we never get "Server started". The Dev server runs, but the actual application server gets stuck on the compiling screen. This repo, which is the boilerplate from 2 weeks ago, works fine.

CSchank · 2023-06-06T19:34:26Z

Sorry, I know that's not much of a bug report! But it didn't give me much more information. Here's how it gets stuck:

mpscholten · 2023-06-06T19:38:20Z

Interesting. Can you it with the env var DEBUG=1 set? Then the terminal will output lots of debug info. Could you share that debug info here?

Something is wrong with postgres. Can you run make postgres to start the postgres server manually? This will likely output the error postgres receives on startup

I wondered if it was something about Postgres. Weird... is it not being installed for some reason?

Can you share what is in .envrc?
