找不到模块的声明文件

Question

I am trying to use a nodejs package which I created, can someone point out what am I doing wrong.

here is how the package structure looks like:

node_modules
 |__my_commons
 |   |__dist
 |       |__src
 |       |    |__helpers.d.ts
 |       |    |__helpers.js
 |       |    |__index.d.ts
 |       |    |__index.js
 |       |__node_modules   <=This got recursively installed
 |       |__.npmignore
 |       |__package.json
src
 |_app/app.component.ts <= Here I am using it

my_commons/package.json

helpers.d.ts:

index.d.ts:

export * from "./helpers";

index.js:

    for (var p in m) if (!exports.hasOwnProperty(p)) exports[p] = m[p];
}
Object.defineProperty(exports, "__esModule", { value: true });
__export(require("./helpers"));

app.component.ts:

import {Helpers} from 'my_commons';

The error:

[ts] Could not find a declaration file for module 'my_commons'. '/Users/ishandutta2007/Documents/Projects/my_proj/node_modules/my_commons/dist/src/index.js' implicitly has an 'any' type.

Answer 1

You did not indicate in your package.json that your my_commons package has typings in it:

// my_commons package.json
{
  "typings": "dist/src/index.d.ts"
}

Answer 2

如果您不能只导入简单的 .js 文件 - 尝试检查并在tsconfig.json中将“ allowJs ”选项设置为true 。

Answer 3

You Should try this

npm i --save-dev @types/<module_name>
