No output generated

I’ve looked through all the other topical issues and it seems even with the latest version I still cannot get it to produce any output, despite saying it completed just fine 😦

OS: MacOS 12.0.1 package version: 0.6.1

Schema

generator client {
  provider = "prisma-client-js"
}

generator erd {
  provider = "prisma-erd-generator"
  output   = "ERD.png"
}

generator nestgraphql {
  provider               = "node ../../../node_modules/prisma-nestjs-graphql"
  output                 = "../src/@generated/"
  reExport               = Single
  fields_Validator_from  = "class-validator"
  fields_Validator_input = true
}

datasource db {
  provider = "postgresql"
  url   = env("DATABASE_URL")
}

model User {
  /// @validator.IsUUID(all)
  id        String   @id @default(uuid()) @db.Uuid
  /// @Validator.IsEmail()
  email     String   @unique
  /// @Validator.Length(8, 64)
  password  String
  /// @Validator.IsJSON()
  roles     Json[]
  profile   Profile?
  /// @HideField({ output: false, input: true })
  createdAt DateTime @default(now())
  /// @HideField({ output: false, input: true })
  updatedAt DateTime @default(now())
}

model Profile {
  id        String @id @default(uuid()) @db.Uuid
  user      User   @relation(fields: [userId], references: [id])
  userId    String @unique @db.Uuid
  firstName String
  lastName  String
}

Console log says everything is fine

✔ Generated Entity-relationship-diagram to ./prisma/ERD.png in 621ms

But no diagram is produced.

Same issue there

✔ Generated Entity-relationship-diagram to .\prisma\prisma-schema.svg in 106ms

But no file to be found anywhere

• Node 16
• Windows 10
• prisma@3.6.x
• prisma-erd-generator@0.6.1

And similar kind of issue, a node_modules path issue, because I’m using workspaces in this project (but I guess any DnD or modern npm replacement could cause similar issues)

Dirty workaround

Change the path to match the current project folder structure

const mermaidCliNodePath = path.resolve(path.join('node_modules', '.bin', 'mmdc')); // cant find the library
const mermaidCliNodePath = path.resolve(path.join('..', '..', 'node_modules', '.bin', 'mmdc')); // this works in my case

Better workaround

Also install the mermaid-cli as a dev dependency, to make sure it’s available in the local ./node_modules/.bin/

yarn add -D prisma-erd-generator # install this library
yarn add -D @mermaid-js/mermaid-cli # Workaround: install mermaid-cli locally

I confirm, now it throw an error if mermaid-cli is not available locally 👍

Error: 
✔ Generated Prisma Client (3.6.0 | library) to .\node_modules\@prisma\client in 348ms

Error: Expected mermaid CLI at C:\Users\{PROJECT_PATH}\node_modules\.bin\mmdc but this package was not found.

Now I get new trouble in docker deployment, if I try to run prisma generate it explode because the path to the documentation does not exist 😄 But that’s another issue

Prisma schema loaded from prisma/schema.prisma

Output directory "/app/docs/pages/" doesn't exist

Error: Command failed: /app/apps/api/node_modules/.bin/mmdc -i /tmp/prisma-erd-DufAnG/prisma.mmd -o /app/docs/pages/database.svg -t default -c /tmp/prisma-erd-DufAnG/config.json

Sadly I don’t see any argument in prisma generate, to run only certain generators
