I'm deploying a Rails app on Heroku which requires a gem that looks for an executable in PATH. I put my executable inside /vendor/bin and then proceeded as below:
As explained in Heroku docs here, I created a .profile.d directory in the root of my app and then in it, I created a file called path.sh. In path.sh, I set the PATH variable like this:
PATH="$PATH:/app/vendor/bin"
or this
PATH=$PATH:$HOME/vendor/bin
But neither seems to work. The app is deployed successfully but when I run it, I see an application error, and in my logs, I see that this executable could not be found in PATH, thus the application crashed. The script (.profile.d/path.sh) is run for sure though, because in my Heroku logs, I am able to see other commands and the print outs I put in the very same file.
Does anyone know what to do in order to make this work? Thanks in advance.

very new to all this. I am following a tutorial to get Heroku running through ruby on rails.
I have Microsoft Windows so I am currently following Heroku's official tutorial and am stuck here
I installed PostgresSQL 10.1 using windows installer x86-64 and have noted my login information for Postgres.
However, I do not understand this part:
Remember to update your PATH environment variable to add the bin
directory of your Postgres installation. The directory will be similar
to this: C:\Program Files\PostgreSQL\<VERSION>\bin. If you forget to
update your PATH, commands like heroku pg:psql won’t work.
The closest thing I could find to an explanation and tutorial was this Java site.
I went inside Enviromental Variables and set the system path to: C:\Program Files\PostgreSQL\10\bin
However, when I tried testing it out by typing in heroku pg:psql, it said no app specified so I'm unsure if I did it correctly or not.
Also, the next tutorial step is:
Open the config\database.yml file and set the username and password
for your local (development) database. Look for these line:
I searched and I have no such file on my computers. Needless to say, I'm stumped. Any assistance to progress through the tutorial is appreciated. Thank you.
regarding your first error, the problem is that you are not specifying for which app you want to open the database cli (psql). Hopefully, the solution is easy:
heroku pg:psql --app app_name
# or
heroku pg:psql -a app_name
About the second question, the tutorial assumes that you have already created an application.
If you go to the root path of your project, you will find some subfolders such as app, config, db, lib, public, tmp, vendor.. Here you will find config\database.yml.
Trying to run a project that was provided by a client.
I have the correct versions of Ruby, Gems, Rails, Bundler, Homebrew etc installed.
When I run rails server I get the following error in terminal.
.rvm/gems/ruby-2.2.2/gems/airbrake-ruby-1.0.4/lib/airbrake-ruby.rb:288:in `call_notifier': the 'default' notifier isn't configured (Airbrake::Error)
After much time spent on Google I couldn't find a fix on this.
Here is a screenshot of the whole terminal error message which I get the feeling these other lines could be related.
It looks like a previous developer may have hardcoded a commit hook in the application, pointing to a file in their local .git folder (and which you don't have).
I'd recommend either asking the developer to provide the missing file, create a dummy file in the same place, or removing that line.
I'm relatively new to Rails as well as using PassengerPhusion. I am running an Ubuntu server on Azure, and have the demo app that Passenger provides working fine. I've even changed the text on the homepage.
My question is this:
In my directory, the file directory's name for the app is passenger-ruby-rails-demo and while I am experimenting, i am changing the name of the directory to something like passenger-ruby-rails-demo-test and it returns an error message when viewing fleetpro.cloudapp.net.
I've tried looking through files trying to figure out how this is routed but haven't had any luck. Is there a file within the Rails installation that is telling Passenger to be inside the specific passenger-ruby-rails-demo directory? Pretty newbish question, but it is really bothering me!
I'm not sure about how the naming convention works in regards to the root directory name of your app "passenger-ruby-rails-demo", but I believe the name of that directory is important to running your Rails app, and might have to do something with the name of the module in your config/application.rb file which is named after your Rails app.
There is a solution though: use gem rename.
Add gem rename to your Gemfile and run bundle install.
Then in your app's root directory, run this:
rails g rename:app_to New-Name
This will basically "clone" the app with your new name. You may have to check to make sure all your config files are present afterwards, but from my experience using it, it was a quick breeze. You will most definitely have to push the new renamed app back to git or Azure.
EDIT
As an example I renamed a Rails app to show what you could expect from the output after running the command:
The Rails app's name isn't the problem, it's the PassengerAppRoot switch you'll be using:
PassengerAppRoot /path/to/your/app
Rails doesn't actually care which folder it's put into, so renaming Rails won't fix your problem.
Renaming Rails only changes the internal class references within your application (things like Rails.application.name which have very subtle implications for your app).
In your Azure server, you'll need to locate either your .htaccess / httpd.conf / nginx.conf file, and change the PassengerAppRoot to your new path. This should resolve the issue.
Up until now I've been using script/runner to forward bouncebacks to eblast-bounceback#mydomain.com and eblast-bounceback#dev.mydomain.com. However it is no longer working in Rails 4.0. I also can't seem to find a good resource online to illustrate how to do it. I usually get directed to the 'whenever' gem - but that's for cron jobs, not for 'piping to programs'.
So this is essentially what I'm currently doing, but is failing:
|/home/user/rails/dev.www/script/rails runner 'EBlast.receive(STDIN.read)' -e development
How do I get this to work? I'm not on Rails 4.1, I'm on 4.0. FWIW I do not have bin/rails. The above command yields "no such file or directory".
There were actually a few things I needed to do.
The email eblast-bounce#dev.mydomain.com was considered 'unroutable'. At first I figured it was because there wasn't any MX records for the subdomain, so I added one. But then I still got the error. I had manually updated the aliases file in /etc/valiases to pipe to the program using a symlinked directory (because I was deploying with Capistrano, and the directory ends up changing after every deploy). Turns out symlinks don't work for some reason when it comes to exim routing (/home/me/rails_deployments/dev.www/current/bin/rails fails). Maybe I'm wrong about the symlinks thing but the problem went away when I used the solution below.
This problem however was solved when I eventually came to another problem (/usr/bin/env: ruby: No such file or directory). I'm using RVM to manage rubies/gems, and apparently the email forwarder didn't know what ruby was. This leads to the final solution:
(when in cPanel, "pipe to program" assumes the user home directory (/home/me/))
.rvm/wrappers/ruby-2.1.0#website/ruby /home/me/rails_deployments/dev.www/current/bin/rails runner 'EBlast.receive(STDIN.read)' -e development
Where ruby-2.1.0 is my current ruby version, and #website is the gemset used by the EBlast.receive code base.
EDIT: Spoke too soon, the command has its own set of problems...(gemfile not present). This is ludicrous.
I'm trying to customize and modify Spree Commerce, but none of the standard asset files/images/views are available under either app/views, lib/assets, or anywhere else I can think to look. I'm trying to go through their tutorials, but I can't find anything to edit. Is there another command I need to decompress everything or something? Thank you so much for any help!
The way I over came this is to download the main spree gem, via github.com, look where the images are located then creating the images I wanted to override in my local app/assets directory with the same path run:
rake assets:precompile:nondigest
restart webrick/pow or any other web server you are running and voila!
I'm guessing you're not really familiar with how gems work. As people here have said, these are not going to automatically show up in your core app directory, but the gemfile and running bundle install knows how to reference them.
So you need to find those gems to figure out the file names, as you said. If you want to view the gemfiles run this command in the terminal:
$ bundle open spree_frontend
If you get this error:
To open a bundled gem, set $EDITOR or $BUNDLER_EDITOR
then you haven't set up the editor, so do this:
export BUNDLER_EDITOR=sublime
Then redo the bundle open command. This should open the spree_frontend directory which will let you investigate the file names/paths and the assets. If you want to change an entire template, you need to create that file matching its name and path exactly as it is in the spree gem (spree/layouts/spree_application.html.erb for example) then when you edit it your rails app will render the code in your core app directory thus overriding the spree gem.
That make sense?
