Prisma1: Prisma seed with .js files throws error in console

[jhalborg]

Bug Report

Current behavior
Seeding with .js files throws the following error in console:

Seeding based on yarn ts-node ./database/seeding/seed.ts !
 ▸    cross_spawn_1.default is not a function

Reproduction

1. Use Typescript Advanced boilerplate
2. Make the following changes to prisma.yml

seed:
  # import: seed.graphql
  run: yarn ts-node ./database/seeding/seed.ts

Run prisma seed, receive the error

Expected behavior?
No error, the script will run

Additional notes
Using a post-deploy hook will run the script, but that's not optimal seeing as it will run on every deploy, and cannot be used with prisma seed command

hooks:
  post-deploy:
    - graphql get-schema --project database
    - graphql codegen
    - yarn ts-node ./database/seeding/seed.ts

My seed.ts for reference:

const TAG = 'seed.ts';
console.log(TAG, `Hello from seed!\n`);

const seed = () => {
  console.log(TAG, `in function\n`);
};

seed();

Output from prisma version:
prisma/1.8.3 (darwin-x64) node-v10.2.1
