npm install error - Wiki installation step #5 OTM tiler

[seitam]

Hello guys, 

First of all thank you for sharing such amazing project, I really appreciate your work. 

I would like to test a OTM Production server using a AWS-Free Tier (Running on 1CPU 1GB of RAM, 30GB of SSD, Ubuntu Server 14.04.05 LTS).

I have followed the Wiki Installation steps although I faced some problems that I had to bypass (basically using this Google group & Google searches). My intention is to share with the community the installation process if eventually I get a production OTM instance running.

I would like to clarify the installation changes that I've applied just in case they may have any impact with the hurdle I found in the step number 5.

# Steps 1-2: No problems to report

# Step number 3: Installing Django and OTM Django Apps

- Error when issuing: "pip install -r requirements.txt"

How I've solve it: "sudo pip instal -U pip", "pip2 install -r requirements.txt"

- Error again when issuing: "pip install -r requirements.txt" (strict mode error)

How I've solve it: 

#apt-get install -yq npm

npm install -g nave

NODE_VERSION_FOR_WEBPACK=4.8.0

nave usemain $NODE_VERSION_FOR_WEBPACK

- Error when running "npm run build" (missing binding)

How to solve it:

"cd /usr/local/otm/app/node_modules

rm -R node-sass

npm install"

- Error when running the following line, there is a typo, change to "clear" not "clean"

"python opentreemap/manage.py collectstatic --noinput --clean"

# 4: Install the OTM ecoservice: I've found no problems in this step. 

# 5 : Install the OTM tiler

- Error While running "npm install":

On this forum I found some interesting pots regarding the OTM tiler npm installation: https://groups.google.com/d/msg/opentreemap-user/Q9DQG2lx4-c/6j4FMrywAwAJ

I've tried to upgrade and downgrade npm unsuccessfully. 

At the moment I've have the following error output: https://pastebin.com/XKMb3r5J

Could anybody shed any light on this issue?

Thank you very much, 

Best regards.

My bad! I didn't noticed that the problem resided on memory shortage! (as the user https://groups.google.com/d/msg/opentreemap-user/neb1DJX2nr0/Uil_ZBRrBgAJ answered creating a SWAP space should do the trick) - and IT DID!

A SWAP with 4GB of memory solved the issue:

sudo /bin/dd if=/dev/zero of=/var/swap.1 bs=1M count=4024
sudo /sbin/mkswap /var/swap.1
sudo chmod 600 /var/swap.1
sudo /sbin/swapon /var/swap.1

Sorry for the Spam.

Regards,
