Running the first example in the docs
https://github.com/inversify/InversifyJS/blob/master/wiki/classes_as_id.md

Expected Behavior

It should compile without issues

Current Behavior

I obtain the following error:

Katana = __decorate([
^

ReferenceError: __decorate is not defined

I had to install ts-helpers and enable support for them in tsconfig "importHelpers": true,

[dcavanagh]

the problem is in your tsconfig.json. Typescript is not creating the __decorate function in the file.

set "noEmitHelpers": false,

[Deviad]

Yes, correct. Thank you.
