Cannot find module ts-node

[marticrespi]

Description

When I execute graphqlgen doesn't work, it tells me that ts-node is missing from graphqlgen/dist/parse.js

Steps to reproduce

Only I have installed it with these dev dependencies..

    "@types/aws-lambda": "8.10.19",
    "@types/graphql": "14.0.7",
    "@types/ws": "6.0.1",
    "cross-env": "^5.2.0",
    "graphqlgen": "^0.6.0-rc8",
    "prisma": "^1.26.6",
    "ts-node": "8.0.2",
    "typescript": "3.3.3"

Expected results

Generate the code successfully.

Actual results

$ graphqlgen
module.js:540
    throw err;
    ^

It's strange, throw same error when I want to know my installed version. But it's the last version, 0.6.0-rc8.

$ graphqlgen --version

    throw err;
    ^

issue here 19f5bce#diff-aeb8c724fbf89c652a9b9d6531803566R6

possible solutions:

1. move ts-node from dev-dep to dep
2. move ts-node from dev-dep to optional-dependencies; then use dynamic import (require) and raise manual error if ts-node not found (tell user that they need to install ts-node to use schemas in ts files)

Option 1 increases install time and dep tree complexity for all while Option 2 only does so for users using the schema-in-ts-file feature. But Option 2 requires more effort from users that are using the schema-in-ts-file while option 1 would Just Work.

From what I see at http://npm.anvaka.com/#/view/2d/ts-node option 1 seems fine.
