Hello,
I have created a Python web app. I used Flask and PostgresSQL with Prisma for my database.
While building the site on Vercel I got this error: [ERROR] RuntimeError: The Client hasn’t been generated yet, you must run prisma generate before you can use the client.
See Troubleshooting - Prisma Client Python.
I updated the build command in the project setting to “vercel build && prisma generate”, I also added this line to vercel.json: ““buildCommand”: “vercel build && prisma generate””. And I tried a build.sh file. But nothing seems to work.
my full vercel.json:
{
“version”: 2,
“builds”: [
{
“src”: “index.py”,
“use”: “@vercel/python”,
“config”: {
“buildCommand”: “sh vercel_build.sh”
}
}
]
}
This is the build log:
