Just got the same error, the second time running the command npx @better-auth/cli generate. In a Next.js, just started the project.

On a Mac (OS 14.6.1)

import { betterAuth } from "better-auth";
import { prismaAdapter } from "better-auth/adapters/prisma";
import prisma from "./prisma";

export const auth = betterAuth({
  database: prismaAdapter(prisma, {
    provider: "postgresql",
  }),

  emailAndPassword: {
    enabled: true,
  },
});

Node.js v20.16.0

UPDATE: Just ran yarn and it is now working. Note that I am 100% sure I had the node_modules folder previously, and had just in a few minutes started up the project, installed shadcn/ui, Prisma and better-auth, and spun a Postgres up locally with Docker.

@LarsLrn commented on GitHub (Mar 4, 2025):

Encountered the same issue and found a solution. Add the CLI and babel to your dev dependencies:

    "@babel/core": "^7.26.9",
    "@better-auth/cli": "^1.2.2",

Then install and run npx @better-auth/cli generate

@Bekacru commented on GitHub (Mar 23, 2025):

@CatStudioApp this is related to your setup with your package manager and how npx executables are resolved. I don't think this is something we can resolve directly. And this isn't a critical part of the library. It's a "goody" we provide to make setting it up easier.
