When I run heroku run lein repl on my Clojure app hosted on Heroku, I'm seeing it quit without being able to access the REPL. Here's the output:
$heroku run lein repl
Running lein repl on ... up, run.7753
Downloading Leiningen to .lein/leiningen-2.6.1-standalone.jar now...

The Heroku process was running out of memory as I was on a 1x dyno. Running with the following allows the REPL to start:
heroku run lein repl --size=standard-2x
Error message at the console isn't too helpful, but the heroku logs pointed to a memory issue.

I have successfully deployed a django app on heroku using this guide. The heroku cli is installed as a snap application on my system - I'm running Fedora 32 on a Dell xps 15 - and everything seems to be working fine except when I try to run the app locally.
When I attempt to run the app locally, I get the following error:
$ heroku open
▸ Error opening web browser.
▸ Error: Exited with code 4
▸
▸ Manually visit https://[myapp].herokuapp.com/ in your browser.
I tried variations of the command to no avail:
$ heroku open -a [myapp]
$ heroku open -r https://git.heroku.com/[myapp].git
When, instead, I run it with heroku local it runs without any problems.
I look at the logs but couldn't find any clues. Neither was I able to find any useful information.
What am I missing?
Try setting the browser in your ~/.bashrc using export BROWSER=
If someone uses Windows Subsystem for Linux, set the BROWSER environment variable in the corresponding shell configuration file (e.g., ~/.zshrc) to wslview.
export BROWSER=wslview
I have experience with Ruby on Rails but I'm trying to run Stringer the self-hosted RSS reader which is only Ruby. They suggest using Foreman to run the project which is fine, I can get the project up and running. However, for the life of me I cannot figure out how to keep the project running when I close the terminal.
I believe the Procfile is important in this process?? So here is mine.
web: bundle exec unicorn -p $PORT -c ./config/unicorn.rb
console: bundle exec racksh
Please forgive my ignorance. I'm mostly an iOS developer.
Sounds like you just want to daemonize the process, in which case just run:
foreman start &
I've been trying to get a heroku console session going on cedar and am having no joy.
The old way was:
heroku console
I understand the new way involves 2 steps:
heroku run bash
then
$ rails console
but at the heroku run bash stage i keep geting:
heroku run bash
Running `bash` attached to terminal... up, run.1
!
! Timeout awaiting process
so i checked there isn't a port blocking issue and
telnet rendezvous.heroku.com 5000
gives
Trying 50.19.103.36...
Connected to ec2-50-19-103-36.compute-1.amazonaws.com.
Escape character is '^]'.
which is as expected i think
what am i doing wrong and what do i need to do to get this console up and running?
Thanks!
PS I have tried - heroku run console - also, and that times out too.
In cedar every command that needs to be attached to terminal uses run.
ex:
heroku run console
heroku run rake db:migrate
When its not necessary to be attached don't use the run:
ex: heroku logs
The new way is heroku run console
Ok - it was obvious after a few hours of sleep. Simply had to update the heroku gem that had got corrupted somehow on my mac. If you have something like this problem, then do that first...
In my old Ruby 1.9.2 Sinatra apps running on Bamboo stack, heroku console provided a shell that not only initialized Active Record but also logged to a history file in my .heroku directory.
After moving to Heroku Cedar stack and using Ruby 1.9.3, I found heroku run console did not load any of my Active Record models. I fixed that by writing a small ruby script to initialize Active Record and load my models.
I execute this using the awkward heroku run 'bundle exec irb -r ./console'
This IRB console fires up fine and gives me access to my model data, but no history is logged.
1) Why is heroku run console so neutered?
2) How can I get my console sessions to log to history?
Please?
Thanks
Add the following line to your Procfile:
console: bundle exec irb -r ./console
Keeping the history is not easily possible, as it will spin up a dyno for every new invocation (cedar stack doesn't keep the history for Rails console, either). You could try using rlwrap to keep your history on the local machine.
From the docs:
You can use heroku console as a stand-in for Rails’s script runner, to
run one-time commands directly from the command line
and
Without an argument, heroku console launches an interactive console
similar to irb or the Rails script/console command
run console is aimed at running the Rails console, or irb.
Trying to debug a new Heroku deployment - seems to be missing a db table. To do this, I'm running heroku run console but I get back :-
Running console attached to terminal... up, run.7
sh: console: not found
under both my Linux and Windows environments
What have I missed to get this working?
[Very late update : this is for a Java Heroku app, not a RoR one, so anything related to rails is a little lost on me]
on Celadon Cedar Stack it is changed to:
$ heroku run bash
$ heroku run bash
then
…#…:/app$ script/rails console
It worked for me. Though the second step is specific to Ruby on Rails – I don’t know the equivalent commands for other platforms and frameworks.
To run rails console, it's just:
heroku run rails console
