Package installation of cffi (python) fails because libffi-dev is missing

As the title says, installing cffi fails with an error. I think this is because the package libffi-dev is missing on the host. Here is the full error log:

Try adding a nixpacks.toml to your project:

[phases.setup]
nixPkgs = ['...', 'libffi']
nixLibs = ['...', 'libffi']

[phases.setup]
nixPkgs = ['...', 'libffi']
nixLibs = ['...', 'libffi']

Nice tip, but it doesn't solve it. Anyway, I solved the problem by switching to another lib.

what did you end up using? for any future people who may come along with this same issue

bW9ubwoOP•17mo ago

I moved from the argon2-cffi package to passlib.

bW9ubwoOP•17mo ago

Sorry to come back to this topic. But it seems that passlib needs also the argon2-cffi package. So, I try your solution again and also update the argon2 package. And what should I say, it works now.
