Why does the "The keyword 'interface' is reserved" error occur when using the npm package?

Question

typescript

I decided to post my npm package because I thought that it would be useful not only to me, but also to other people. When I try to download my own package to another project, I get an error in the browser:

The keyword 'interface' is reserved (3:0)
File was processed with these loaders:
 * ./node_modules/source-map-loader/dist/cjs.js
You may need an additional loader to handle the result of these loaders.
