Prisma: `prisma2 init` fails in Yarn Workspaces

[renemonroy]

Problem

prisma2 init fails when the folder created is expected to be a workspace. It'd be ideal to have a Prisma project inside a monorepo.

Project tree

This is a simple example:

Directory structure

• my-project/
  
  
  
  • .gitignore
  
  
  • package.json
  
  

.gitignore

node_modules

package.json

{
  "name": "my-project",
  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",
  "private": true,
  "workspaces": [
    "my-project-api"
  ]
}

Error

The structure above fails:

❯ prisma2 init my-project-api

I can confirm this. First of all, we don't have a version property in the package.json that we generate so the yarn is ignoring that package which in turn doesn't allow us to install @prisma/photon. We need to fix this.

The new non-interactive init CLI solves that issue.

So first update your prisma2 package to the latest, it should be version 2.0.0-preview020 (or use npx like below) then:

• yarn add @prisma/client in root project folder
• npx [email protected] init my-project-api and follow instructions
• cd my-project-api
• npx [email protected] generate

This issue is fixed in the latest alpha version of prisma2.
You can try it out with npm i -g prisma2@alpha.
