Cannot use ts-node to run custom script in Expo project

[Lpaydat]

Hello, noob here.

I have some ReactJs project which is run perfectly on every aspect.
But recently I want to make it monorepo and I chose Expo for this job.

I can make most of code works except some custom scripts.
It say SyntaxError: Cannot use import statement outside a module and the line of code that lead to this error was node_modules/expo/AppEntry.js which is in the main parameter in package.json.

This is the full log:

$ ts-node -r tsconfig-paths/register --project scripts/helpers/tsconfig.json scripts/customScript.ts
/home/username/Workspace/project/node_modules/expo/AppEntry.js:1
import 'expo/build/Expo.fx';
^^^^^^

    at Module._compile (internal/modules/cjs/loader.js:1128:30)
error Command failed with exit code 1.

and this is the content of scripts/helpers/tsconfig.json:

  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "jsx": "preserve",
    "lib": ["dom", "esnext"],
    "moduleResolution": "node",
    "noEmit": true,
    "skipLibCheck": true,
    "resolveJsonModule": true,

    "noImplicitThis": false
  },
  "exclude": ["node_modules"],
  "include": ["next-env.d.ts", "**/*.ts", "**/*.tsx"]
}

This error not occur on every scripts, just some custom script commands and all error disappear if I remove main field from package.json.

I tried to search for solution for hours and tried a bunch of methods with no results. T__T

Do you have a reproduction I can try?

@blakeembrey Sorry for late reply.

I have created an example to reproduce this error, you can see it here ts-node-next-expo.

It's the customScript command.

@Lpaydat Are you on Node.js 13?

[trusktr]

Just checked it out, node_modules/expo/AppEntry.js is an ES Module. The issue is #935
