Do I need do install pip

I'm installing a custom package in railway.yaml but getting pip error - how can I fix it? railway.toml:

[build]
builder = "nixpacks"
buildCommand = "git clone https://username:[email protected]/org/my-module.git && cd my-module && pip install -e ."

[build]
builder = "nixpacks"
buildCommand = "git clone https://username:[email protected]/org/my-module.git && cd my-module && pip install -e ."

logs:

0.278 Cloning into 'my-module'...
4.171 /bin/bash: line 1: pip: command not found

0.278 Cloning into 'my-module'...
4.171 /bin/bash: line 1: pip: command not found

Why is this not working?

If your project isn’t detected as a python project (doesn’t have a main.py or isn’t the primary language) then you’ll have to tell nixpacks to install python. Create a nixpacks.toml file and add “python3” to the providers section

make sure to include the “…” as well as that tells nixpacks to install the detected packages as well @Charles_ for visibility ^

the real question is, why are you having your build clone a repo instead of letting railway's infra do that for you?

Charles_OP•8mo ago

it seems that adding requirements.txt at project root fixed it - but I only need setup.py. Would that also work with nixpacks.toml if I remove requirements.txt? @Brody would love to hear the better alternative - this does feel clunky I'm actually installing 6 different private module which makes for a very long and awkward buildCommand

Brody•8mo ago

attach your repo to the service

Charles_OP•8mo ago

That's what I've done for the main app, but it has deps on 6 private modules

Brody•8mo ago

Fair, this sounds like an absolute pain to do with nixpacks, i would highly recommend this be done with a Dockerfile

Charles_OP•8mo ago

Thanks I will give it a go @Brody just checking; are you aware of any issues/downsides from using supervisord inside Dockerfile for managing long-running processes? I would have them split as two railway services but both processes need access to a shared volume which AFAIK isn't possible.

I use supervisor on a demanding php-fpm service on Railway and never had any issues with it.

Charles_OP•8mo ago

nice, good to hear!

Brody•8mo ago

yeah it's totally fine, but personally, I much prefer parallel far far simpler https://github.com/railwayapp-templates/browserless/blob/main/scripts/start.sh

Charles_OP•8mo ago

Thanks, how can I avoid this Dockerfile caching? This layers runs git clone & pip install on repo's I've made commits to

Brody•8mo ago

set a service variable NO_CACHE to 1

@Brody please send me friend request if you're interested in paid work (deploying docker-compose to Railway)

Brody•8mo ago

well I'm honestly just more curious as to what you want to deploy more than anything
