Why Babel copies my JS-files without conversion from JS6 to JS5?

Question

I have a problem with Babel CLI. It copies my JS-files without conversion from JS6 to JS5. Here is my small "Hello World" project code sources for demonstrate of this problem.

In the scripts section of the project.json file I added the row:

"babel": "babel src/js -d test/lib"

I launch it by the command:

npm run babel

Why does it happen?

Thank you.

@Quentin I do it according the official example: https://babeljs.io/docs/usage/cli/ — Andrey Bushman, Jun 26 '17 at 10:08
There are **lots** of examples on that page, and your code doesn't match any of them. (It doesn't even come *close* to matching any of the examples which modify the code). — Quentin, Jun 26 '17 at 10:09
@Quentin look first example this section: https://babeljs.io/docs/usage/cli/#babel-compile-directories — Andrey Bushman, Jun 26 '17 at 10:11
It uses `--out-dir`, you use `-d`, so it doesn't match … and that example doesn't transform the code in any way. It is just showing you how to specify what directories to work on. — Quentin, Jun 26 '17 at 10:12
(I'm assuming you haven't bothered creating a `.bablerc` since you didn't mention on in the question). — Quentin, Jun 26 '17 at 10:12
@Quentin that section writes that `-d` is short variant of `--out-dir`. — Andrey Bushman, Jun 26 '17 at 10:13

I managed to find the answer myself. I publish it here so that newcomers such as myself do not stumble on the same rake.

It is necessary to install babel-preset-es2015 and add the .babelrc file. Now it works.
