bundle update rails give an error

Question

Here is my code and output in console:

root@a:/home/rails/car_main# bundle install

You have requested:
  rails = 4.2

The bundle currently has rails locked at 4.0.2.
Try running `bundle update rails`

Here is what I did and output:

root@a:/home/rails/car_main# bundle update rails

After this when I type bundle install I still get the error

Okay. What do I do with memory? I use digital ocean droplet for $5 my website is quite simple. I did what suggested here in this question: https://askubuntu.com/questions/253466/why-am-i-frequently-getting-this-cannot-allocate-memory-error here is output:

Update 3 I tried to stop and start postgres( I am not sure if I googled how to this correctly so here the code and output:

UPDATE 4: I print htop: here is the output: What processes should I kill?

Update 5:

I ran once again bundle update Then I got some error and promt to install bundler so I installed it with

root@a:/home/rails/car_main# apt-get install bundler Then I did once again bundle update:

root@a:/home/rails/car_main# bundle update

    from /usr/bin/bundle:7:in `<main>'

UPDATE 6: So I run bundle update once again and it gave me an error that cannot install sqlite3 and suggested to install it manually so i did it and here's the output:

root@a:/home/rails/car_main# gem  install sqlite3 -v '1.3.8'

I will remove sqlite version in gemfile hope it helps

why downwote? Did I miss something? I print the command get an error. Did what I was promt, got strange output and asked a question here providing details. Whoever downvoted me explain what is wrong with this question? — user2950593, Feb 18 '16 at 17:28
if I had to guess would be associated with not being aware of where gcc is: http://stackoverflow.com/questions/6119153/why-do-i-get-a-bcrypt-ruby-gem-install-error — Drew, Feb 18 '16 at 17:36
Try stopping postgres and your rails server, then run bundle update again. — Robert Nubel, Feb 18 '16 at 17:38
@Drew see an update 2 - i print it as suggested in question you posted - it doesn't work — user2950593, Feb 18 '16 at 17:45
You're still running out of memory (hence why Postgres can't start up again). Stop every process on your machine that you can, and use the top command to monitor how much memory you have free/used. — Robert Nubel, Feb 18 '16 at 17:47
use `htop` to track the process that eats your memory, also yout could use `df` to check your disk space, btw for that price you could get 4 times more ram, fighting lack of ram is usually not worth it unless of course you want to learn how stuff works and have time to spare :) — mmln, Feb 18 '16 at 17:48
@RobertNubel so I did htop to see processes as suggested by mymlin. See `update4` Should I kill all of them? How do I kill process btw? — user2950593, Feb 18 '16 at 17:54
It doesn't look like there are any more processes you can kill, at this point, and you've got just about all the RAM free you can get on your droplet. Try `bundle update rails` again and see if it works. If not, the easiest solution is to get more RAM; otherwise, you might be able to use compiler flags to tune gcc to use less memory when compiling. — Robert Nubel, Feb 18 '16 at 17:55
@mymlyn if it will solve it would be awesome. I will check if it possible to add ram without destroying a droplet if not I will create a new one. Time is a very preciousthing, I can't afford right now digging so deep=) — user2950593, Feb 18 '16 at 17:57

your issue is related to lack of memory, quoting your stack trace: Cannot allocate memory

considering unicorn workers eat up all your ram you should reduce amount of workers, some more info here,

i noticed that you already killed all the processes; deploy your app, if itll have enough ram everything should go fine (btw: check htop while deploying), if issue persists, there either is memory leak somewhere (update gem versions) or you simply got not enough ram - as i said for that price you should get 4x the resources elsewhere

if you are running all those commands live on your server, you should consider using capistrano in future

regarding Update 5: you should run gem install bundler (I assume you dont have rvm?)

yeah I run this with ssh connection... I am not sure if I can deploy it - now it gives me an error you can see it in update 5=) – user2950593 Feb 18 '16 at 18:07
okay I will consider capistrano. When I will be deploying another rails app in the future) – user2950593 Feb 18 '16 at 18:09
bundler itself is a gem which should be installed in the gemset youre using, updated my answer – mmln Feb 18 '16 at 18:11
Nope I have it - rvm 1.26.11 ( I guess it was pre installed with droplet) – user2950593 Feb 18 '16 at 18:16
Thanks, about bundler=) – user2950593 Feb 18 '16 at 18:16
well it gave me another error `An error occurred while installing sqlite3 (1.3.8), and Bundler cannot continue. Make sure that `gem install sqlite3 -v '1.3.8'` succeeds before bundling.` – user2950593 Feb 18 '16 at 18:22
I guess I should change version of sqlite – user2950593 Feb 18 '16 at 18:22
I do not even need it cause it's production – user2950593 Feb 18 '16 at 18:24
yeah bundle update now went allright and bundle install – user2950593 Feb 18 '16 at 18:31
can you see this question please http://stackoverflow.com/questions/35489976/rails-postgersql-connection-could-not-connect-to-server-connection-refused – user2950593 Feb 18 '16 at 18:51
sorry i can't ask mpre than 6 questions in 24 hours so I will ask you here. I managed to deploy my app but something wen wrong and there is a message that page is unavailable. where I can see app's logs? – user2950593 Feb 18 '16 at 20:06
if you're sure its your app thats throwing an error its in your apps root folder `app_root/logs/your_environment.log`, error could also be related to nginx (if thats what youre using) and unicorn – mmln Feb 18 '16 at 20:13
what if I have nothing in production.log? – user2950593 Feb 18 '16 at 20:37
then most likely the request did not hit your application at all and is stuck on nginx or unicorn instead (or something else, not sure what your stack is... and youre hot fixing production) – mmln Feb 18 '16 at 20:40
