Compile faild with type error about fxts

[sunrabbit123]

It is my tsconfig.json

{
  "compilerOptions": {
    "module": "CommonJS", 
    "target": "ESNext", 
    "outDir": "dist", 

    "strict": true,
    "noImplicitAny": true, 
    "moduleResolution": "node", 
    "sourceMap": true,
    "experimentalDecorators": true, 
    "emitDecoratorMetadata": true, 
    "typeRoots": ["./node_modules/@types"],
    "esModuleInterop": true
  }
}

@sunrabbit123 Maybe when this pr is merged, we expect it to build normally 👍

[ppeeou]

@sunrabbit123 it was released :)

@sunrabbit123 Let me know the tsconfig.json you set up??
and check strict: true https://www.typescriptlang.org/tsconfig#strict

[sunrabbit123]

I set strict : true
because #147 It happened to me, too

@sunrabbit123
I tried creating the environment you mentioned, but the build doesn't fail.
Could you tell me the same environment with codesandbox??

https://codesandbox.io/s/snowy-violet-m12b1o?file=/src/index.ts

It same

Maybe that's what's happening with "reduce."

export const checkArgument: Function = (...args: any[]): boolean => {
  return reduce((a, b) => !!a && !!b, args);
};

But where is the flat referenced?

I think it's a compilation problem.
This is because the error does not appear after removing the 'type' that appears in the error

[sunrabbit123]

but the build doesn't fail at codesandbox, Now I'm confused, too.
