Hi

I am not using firebase.
I did search online for similar problems, but couldn't find any

Environment details

• OS: macOS Sierra, version 10.12.4
• Node.js version: v9.7.1
• npm version: 5.6.0
• @google-cloud/functions-emulator version:1.0.0-beta.4

Steps to reproduce

How to get started?

completed Step1

Step2 npm install -g @google-cloud/functions-emulatorgave permission error so installed using npm install @google-cloud/functions-emulator

this was the output of the after Step2

> @google-cloud/functions-emulator@1.0.0-beta.4 postinstall /Users/name/Documents/helloworld/node_modules/@google-cloud/functions-emulator
> node scripts/upgrade-warning


If you're using the Emulator via the Firebase CLI, you can
disregard this message.

If you're upgrading @google-cloud/functions-emulator, these
are the recommended upgrade steps:

1.  Stop the currently running emulator, if any:

        functions stop

2.  Uninstall the current emulator, if any:

        npm uninstall -g @google-cloud/functions-emulator

3.  Install the new version of the emulator:

        npm install -g @google-cloud/functions-emulator

If you have trouble after upgrading, try deleting the config
directory found in:

    ~/.config/configstore/@google-cloud/functions-emulator

Then restart the emulator. You can also check for any renegade
Node.js emulator processes that may need to be killed:

    ps aux | grep node

npm WARN saveError ENOENT: no such file or directory, open '/Users/name/Documents/helloworld/package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.
npm WARN enoent ENOENT: no such file or directory, open '/Users/name/Documents/helloworld/package.json'
npm WARN helloworld No description
npm WARN helloworld No repository field.
npm WARN helloworld No README data
npm WARN helloworld No license field.

+ @google-cloud/functions-emulator@1.0.0-beta.4
added 310 packages in 29.534s

Step3 used functions start

I got this big error message

Everything worked smoothly
