I am trying to deploy my Django project that uses React on the frontend inside Django app to railway. The app was deployed on Heroku before but after adding a whisper package from openAI the slug size became too big to use it there so I opted to use railway instead. I have another Django project with React running there so the problem comes from the packages.

The problem comes from package called gpt-index which uses pandas package and that's where the error occurs.

What can I do to fix this?

Nix-packs setup:

[phases.setup]
nixPkgs = ['nodejs-16_x', 'npm-8_x ', 'python310', 'postgresql', 'gcc ']

[phases.install]
cmds = ['npm i ', 'python -m venv /opt/venv && . /opt/venv/bin/activate && pip install -r requirements.txt']

[phases.build]
cmds = ['npm run build']

[start]
cmd = '. /opt/venv/bin/activate && python manage.py migrate && gunicorn backend.wsgi'

Full traceback:

  • I have seen this thread before I posted mine and meanwhile this could be the solution I do not know how to implement it on railway. If you have any insight on that I would love to hear. @MarcelPreda – IonicEcommerce Feb 11 '23 at 15:13

The libstdc++.so.6 library is missing. You could try to install nixos package gcc-unwrapped or another one that provides that lib. After installing the library, you might still have to set LD_LIBRARY_PATH before running the program, if the library isn't in the default system path
