Linux server error: Unexpected reserved word

[rockthrower69]

Hello,

I tried setting up the NodeJS server on my Raspberry Pi, and I got this error.

/home/pi/agar-mini-map-master/server/dist/server.js:1
import { Server
^^^^^^

module.js:434
var compiledWrapper = runInThisContext(wrapper, filename, true);

Why am I receiving this error? Is it my fault or is it the server itself?

@rockthrower69 Please provide your environment and steps

[rockthrower69]

I had nodejs already installed. I executed "sudo apt-get update" before executing the server. When I just execute "node server.js" I get this error.

root@rpi-anton-1:/home/pi/agar-mini-map-master/server/src# node server.js

/home/pi/agar-mini-map-master/server/src/server.js:1
import { Server

Appearently "import" isn't correct NodeJS syntax. Maybe I have to install something before?

[dimotsai]

You should execute npm run start instead of node src/server.js. Have you executed npm run build before?

[dimotsai]

Your node version is out-of-date. Upgrade your node package to v0.12 or upper. node -v will print node's version.

[rockthrower69]

"npm run build" is what I tried before, but I also got errors.

When I try to update NodeJS "nodejs is already the newest version.".
"node --version" gives v0.6.19

You have to run npm install first

Your node version is out of date. Please try to reinstall it

[rockthrower69]

Already updated and reinstalled it. It stays the same version and says it is the highest. I use apt-get to install node and npm.

[dimotsai]

What is your Linux distribution? If your package manager does not provide the latest Node.js, you might want to build Node.js from source by yourself. I believe that all problems will be solved as long as you install the latest Node.

[sb2259]

After encountering the above, and other, problems, and eventually getting agar-mini-map running on the Raspberry Pi, I thought I would leave the following comments for any others following in my footsteps:

1. Use Raspbian "Jessie" distribution. I started with a fresh memory card and Jessie Lite after running out of space trying to perform the upgrade from Raspbian "wheezy" on my 4GB card.
2. At the time of writing, agar-mini-map and the v4.x.x.x versions of NodeJS don't seem to work together. Install v0.12.6 of Node using the instructions found here: http://node-arm.herokuapp.com/ making sure you download "node_archive_armhf.deb," listed in the "other options", rather than the "latest" version.
