When trying to deploy Prisma client to Elastic Beanstalk, I am seeing the following errors:

Error: Cannot find module '.prisma/client'

How to reproduce

Follow along this prisma tutorial and attempt to deploy to AWS Elastic Beanstalk

Expected behavior

It to deploy properly.

Prisma information

Package.json :

...
"@prisma/cli": "2.15.0",
"@prisma/client": "2.15.0",
...

tsconfig.json

{
    "compilerOptions": {
      "lib": ["esnext"],
      "outDir": "dist",
      "moduleResolution": "node",
      "esModuleInterop": true,
      "experimentalDecorators": true,
      "emitDecoratorMetadata": true,
      "skipLibCheck": true,
      "forceConsistentCasingInFileNames": true,
    }
  }

I will say I have tried all different variations of tsconfig as well…

Ok, after a bit more investigation, it turned out, that EB is not allowing any postinstall hook to write to the filesystem. There are 2 ways to fix this:

1. `.npmrc`

Create a .npmrc file with this content: unsafe-perm=true This let’s the postinstall hook write into the filesystem as is the case in a normal npm installation.

2. Add `prestart` hook

Unfortunately, EB doesn’t run the postinstall hook of the main application. However, you can add a prestart hook that runs prisma generate like so:

{
  "name": "eb-test",
  "scripts": {
    "start": "node ./bin/www",
    "prestart": "prisma generate"
  }
}

I suggest using the prestart hook to be on the safe side.

And @jimthedev did this start appearing in 2.15.0 or did you see this earlier already?

This is a brand new app so I don’t know but previous versions of Blitz apps worked using prisma so I suspect this is new.

Ok good to know! We’ll let you know here once it’s fixed.

I haven’t tried with 2.14.0 but I certainly can and report back.
