im not sure whats wrong

• node: v11.5.0
• ts: Version 3.3.0-dev.20181214
• tsconfig.json

init.ts

import { loadCacheConfig, loadMainConfig, loadConfig } from '@node-novel/task/lib/config';

export let CacheConfig = loadCacheConfig(PROJECT_ROOT);

export let CLONE_DEPTH = process.env.CLONE_DEPTH || 50;

@node-novel/task/lib/config

import { IConfig } from '../index';
export declare function loadMainConfig(cwd?: string): {
    config: IConfig;
    filepath: string;
};
export declare function loadCacheConfig(cwd?: string): {
    config: {
        last: string | number;
        last_from?: string | number;
        done?: number;
        last_push_head?: string;
    };
    filepath: string;
};
export declare function transform(result: any): any;
export declare function loadConfig<T>(name: string, options?: any): {
    config: T;
    filepath: string;
};
export default loadConfig;

Expected behavior:

init.d.ts

export declare let CacheConfig: {
    config: {
        last: string | number;
        last_from?: string | number;
        done?: number;
        last_push_head?: string;
    };
    filepath: string;
};

export declare let CLONE_DEPTH: string | number;

Actual behavior:

init.d.ts

export declare let CacheConfig: {
    config: {
        last: import("node-novel-info").INumber;
        last_from?: import("node-novel-info").INumber;
        done?: number;
        last_push_head?: string;
    };
    filepath: string;
};

export declare let CLONE_DEPTH: import("node-novel-info").INumber;

Looks like node-novel-info (a dependency of your dependency) exports a type type INumber = string | number which we then use as an alias for all unions of string | number in a program. Since aliases are currently heuristic, this is kinda expected but here it's pretty obviously undesirable.

Declaration emit doesn't make this kind of error anymore
