Hi, I am getting build failed. When I look at the build log the first error I see is: error: … while calling the 'derivationStrict' builtin What is causing the build to fail?

do either of you have a .python-version or runtime.txt file?
Brody
Brody15mo ago
their build is a python project, please do no hijack others unrelated threads

I have a runtime.txt file my runtime.txt contains 'python-3.7.0'
Brody
Brody15mo ago
what version of python do you use locally
KiLo89
KiLo89OP15mo ago
locally I'm using Python 3.7.0
Brody
Brody15mo ago
will your project work on python 3.8?
KiLo89
KiLo89OP15mo ago
No I don't think so

from your build error it looks like railway no longer supports 3.7

I've been running my app on fine on railway for quite awhile now, why the change, were users notified?
Brody

not really how hard would it be to refactor your app to be usable with 3.8 if it's easy, do it, if it's hard I have a solution for that but obviously using 3.8 is highly preferred

what you are saying I should upgrade, what version are supported by Railway? I'd hate to upgrade to 3.8 only to find Railway doesn't support it 3 months later
Brody
Brody15mo ago
3.8 is supported and is the default actually I mean your code might even run perfect with 3.8 it's not a major version bump, try it locally?
KiLo89
KiLo89OP15mo ago
OK I will upgrade, it there a process at Railway where we users can be notified of these type of changes?
Brody
Brody15mo ago
I'll be honest with you, even if there was, this wouldn't be there because railway didn't foresee this it wasn't a planned deprecation, it just came when they upgraded the nix package repository that the builder used

OK thanks
