npm ERR! Cannot read property '0' of undefined when starting Rocket Chat server

[distlibs]

Description:

I git pull latest changes form develop branch and then start Rocket Chat server using command meteor I get npm error:
npm ERR! Cannot read property '0'

I think its related with Live Chat building. Logs then error occurs:

I tried install latest Ubuntu 16.0.3 and start Rocket Chat server using commands:

git clone https://github.com/RocketChat/Rocket.Chat.git
cd Rocket.Chat
meteor npm start

But I get same error. Maybe same linux dependencies missing. Somewhere a month ago I don't got this error and all worked fine.

Server Setup Information:

• Version of Rocket.Chat Server: 0.61.0-develop (fbbe16c)
• Operating System: Ubuntu 16.04.3 64-bit
• Deployment Method(snap/docker/tar/etc): git pull
• Number of Running Instances: 1
• DB Replicaset Oplog: Enabled
• Node Version: 8.9.3 - x64

@distlibs could you try remove your node_modules folders, pull the latest changes and test?

rm -rf node_modules
rm -rf packages/rocketchat-livechat/.app/node_modules
rm -rf packages/rocketchat-livechat/.app/package-lock.json
meteor npm install
meteor npm start

It's a NPM problem, we solve that preventing NPM to create the package-lock file inside the livechat package.

@rodrigok Thanks, it works! I think you can remove packages/rocketchat-livechat/.app/package-lock.json from git repository. When I check git status, it prints:

modified:   package-lock.json
deleted:    packages/rocketchat-livechat/.app/package-lock.json

@distlibs Thanks, I'll remove, maybe someone else added it back.
