# sh: prisma: not found How to fix it.

URL: https://antideploy.com/blog/prisma-generate-command-not-found

The build ran Prisma and could not find it. Add prisma to package.json at the same version as @prisma/client.

**What you see**

```
> postinstall
> prisma generate

sh: 1: prisma: not found
```

## At a glance

- **What it means**: The prisma command is missing
- **The fix**: Add prisma at your client's version
- **Common cause**: It is only in devDependencies
- **On Antideploy**: It pins the version for the build

## What it means

Your build runs `prisma generate`, often in a `postinstall` or `build` script. The `prisma` command is not installed. If it is in `devDependencies`, a production install skips it. If it is not in `package.json` at all, `npx` fetches whatever version is newest, which may not match your `@prisma/client`.

## How to fix it

### 1. Add prisma at the same version as @prisma/client

Use matching versions, for example both `^6.0.0`. Mismatched versions cause errors of their own.

### 2. Move it to dependencies if a production install skips it

If `prisma` is in `devDependencies` and the build says it is missing, list it under `dependencies` instead.

### 3. Commit package.json and the lock file, then deploy again

A failed deploy never counts against your plan.

**package.json**

```
{
  "dependencies": {
    "@prisma/client": "^6.0.0",
    "prisma": "^6.0.0"
  }
}
```

## What Antideploy does

Antideploy recognises this failure. It pins the `prisma` command to the version of your `@prisma/client` in its own copy of your source for the build, and tells you it did. It never edits your repository, so make the fix in your own `package.json` too.

### Why does it work locally?

Locally, `npm install` installs development packages, and `npx` may find a copy already downloaded.

### Do I also need prisma migrate deploy in a script?

No. Antideploy detects Prisma and runs `npx prisma migrate deploy` if you have a migrations folder, and `npx prisma db push` if you do not, before the new version goes live.

### Does this failed deploy cost anything?

No. Failed deploys never count against your plan.

Each platform page covers one part of Antideploy: what it does, where it stops and the questions people ask. [See the whole platform](https://antideploy.com/platform), or [all the guides](https://antideploy.com/blog).

- [Prisma Environment variable not found](https://antideploy.com/blog/prisma-environment-variable-not-found): Prisma needed a variable and it was not set. DATABASE_URL is set for you when your app has a database.
- [Prisma 7 datasource url is no longer supported](https://antideploy.com/blog/prisma-7-datasource-url-no-longer-supported): Prisma 7 removed the url field. Pin Prisma to version 6, or move the connection into prisma.config.ts.
