'Firebase init' command didn't create package.json, index.js and function folder

Question

I’m now trying to create a tutorial app for my Google Home but I faced some trouble. According to this tutorial, I finished following steps of Build fulfillment.

1.Download and install Node.js.
2.npm install -g firebase-tools
3.firebase login
4-1.mkdir sillynamemaker
4-2.cd sillynamemaker
4-3.firebase init
5.select Functions:…
6.select action project(silllynamemaker-***)
7.firebase init

But after step 7, there were only ‘firebase.json’ in current folder, so I couldn’t see functions folder, package.json and index.js.

My console log is below.

$ node -v
v8.6.0
$ npm --version
5.3.0
$ firebase --version
3.13.1

$ firebase init

I'm really glad if someone help me. Thanks in advance.

You must select features you want to initialize by using the arrow keys and spacebar -- none are on by default. See the error message in your pasted log:

⚠  You have have not selected any features. Continuing will simply associate this folder with a Firebase project. Press Ctrl + C if you want to start over.

You can also run firebase init functions to specifically initialize only functions.
