jsnlog producing errors on install

Question

I am having some issues installing and using jsnlog as described on the docs . I keep getting errors when I try to import or use the library.

I tried to import the library as in the docs:

import { JL } from 'jsnlog'

I also tried including it this way (don't what this style is called)

import 'jsnlog';

The errors I get in the console when I run npm run serve are:

ERROR in C:\Users\jeanpierreb\Documents\project\node_modules\jsnlog\Definitions\jl.d.ts
(279,10): error TS2304: Cannot find name 'r'.

ERROR in C:\Users\jeanpierreb\Documents\project\node_modules\jsnlog\Definitions\jl.d.ts
(279,12): error TS2304: Cannot find name 't'.

ERROR in C:\Users\jeanpierreb\Documents\project\node_modules\jsnlog\Definitions\jl.d.ts
(279,20): error TS2304: Cannot find name 'J'.

ERROR in C:\Users\jeanpierreb\Documents\project\node_modules\jsnlog\Definitions\jl.d.ts
(279,22): error TS2304: Cannot find name 'L'.

ERROR in ./app_ts/app.module.ts
(4,21): error TS2306: File 'C:/Users/jeanpierreb/Documents/project\node_modules/jsnlog/Definitions/jl.d.ts' is not a module.

Software Versions I'm including the node/npm/angular versions because I have a feeling the issue may be here. I haven't tried this on other versions of node other than the most recent, but this is a rather large project so I can't readily upgrade npm or node without breaking the app

• Angular 2.1.1
• npm 4.6.1
• node 6.10.3

For completeness here is my tsconfig and package.json

问题是您在Webpack配置中使用了ts-loader ，由于某种原因， ts-loader无法通过使用awesome-typescript-loader jsnlog ts-loader替换ts-loader jsnlog正确编译jsnlog会解决此问题。
