When I run heroku local
my console shows me:
[WARN] No ENV file found
How can I fix this?
Add an .env file. This files contains the local VARS that are different in your local setting from the heroku environment. However, if everything runs fine, you can just ignore the warning, or do touch .env.
You can also differentiate by creating a Procfile.local file and run heroku local -f Procfile.local, to force using a local start script.
I just read: https://devcenter.heroku.com/articles/heroku-local. That explains it all.
For a working example: http://github.com/halcwb/GenUnitApp.git. When you have the heroku toolbelt installed you can heroku local -f Procfile.bash on mac or linux, or heroku -f Procfile.local for windows, and go to http://localhost:3000, to check the result.

Here is a question about the Heroku CLI.
When I run this command inside my local folder for a given app already on the server:
heroku config
I get a list of my environment variables settings.
But if I run the same command from another folder with the same name it does not work anymore.
This shows that the name of the local folder is not enough for heroku config to know which app I am thinking about.
How does heroku config know which app to query on the server?
By default, Heroku infers the app from your Git remotes:
App commands are typically executed from within an app’s local git clone. The app name is automatically detected by scanning the git remotes for the current working copy, so you don’t have to specify which app to operate on explicitly.
You can also explicitly tell it what app to use:
If you have multiple heroku remotes or want to execute an app command outside of a local working copy, you can specify the remote name or an explicit app name as follows:
heroku apps:info --app example
heroku apps:info --remote production
Or via environment variable:
Alternatively, the app name can be specified by setting the HEROKU_APP environment variable.
I've tried many different solutions on the web for this problem, but all have been unsuccessful.
Here's the problem: My app needs to know whether it is being run on Heroku (production mode) or locally (development mode). For this purpose, we want to use environment variables. I've understood that environment variables on Heroku can be set in a .env file. So my attempt was to run heroku run bash -a <app-name> and then to install vim by doing this:
mkdir ~/vim
cd ~/vim
# Staically linked vim version compiled from https://github.com/ericpruitt/static-vim
# Compiled on Jul 20 2017
curl 'https://s3.amazonaws.com/bengoa/vim-static.tar.gz' | tar -xz
export VIMRUNTIME="$HOME/vim/runtime"
export PATH="$HOME/vim:$PATH"
cd -
Apart from crashing repeatedly, vim didn't work anymore when I logged in and out of the shell:
~ $ vim // in the heroku shell
vim: error while loading shared libraries: libXt.so.6: cannot open shared object file: No such file or directory
I also tried heroku plugins:install heroku-vim but running heroku vim after that only resulted in a long delay followed by the normal heroku shell opening, no vim.
I don't really care if I get vim to work. I just want to be able to write in a file named .env on Heroku so I can set environment variables in it.
How can I achieve this?
There is no need for an .env file on Heroku. In fact, such a file won't work very well since
Heroku gets all of its files from your Git repository,
has an ephemeral filesystem, meaning that changes to files like .env will be quickly lost, and
the .env file won't be available on other dynos if you scale your app
As such, creating an .env file on Heroku isn't a good approach.
Instead, you can use its built-in support for environment variables, using heroku config:set <var> <value> or its web UI. Either way, you'll get a regular environment variable.
It is fairly simple.
Just as you added them in your .env file, do the same with heroku's command line and you will see heroku restart and you are all set to fly again.
Just use the command :
(heroku config:set VARIABLE=this_is_the_value)
Remember to use the underscores in the value as spaces are not allowed not inverted quotes (" ")to turn it into a single string is permissible.
I need to see all files from a heroku server from a directory. Is any anyway run command in server using command line or is there file browser heroku dashboard?
Thanks.
I could see the files from command line using the following command
heroku run ls private
But i could not find any file browser in heroku dashboard. Also we could all linux commands there by using heroku run
I've configured a heroku environment variable by using:
heroku config:set METEOR_SETTINGS="$(cat settings.json)"
However, the app fails to launch, and heroku's logs state:
Error: METEOR_SETTINGS are not valid JSON: $(cat settings.json)
Thinking it's not finding my settings.json file. This seems to be the approach I've seen others take. I've tried looking for the root of my app by using
heroku run bash
And changing directories looking for the settings file, and I cannot find it.
It sits in the root directory of my local repository as settings.json
I'm using the following buildpack: https://github.com/jordansissel/heroku-buildpack-meteor.git
I've an existing project that works fine on another machine, but I've just upgraded and from within the project development directory, everytime I run a heroku command I have to post-fix it with --app
I feel like I've missed an application setup stage, but I can't figure out what, as everytime it states:
Run this command from an app folder or specify which app to use with --app APP.
Help appreciated.
You can solve this by adding the Heroku app to your .git/config folder.
If you are in the root of your project, run the following command:
git remote add heroku git#heroku.com:appname.git
This will set a line in your .git/config file which the heroku command line tool uses to figure out what app you're using :)
In other words, your local repo doesn't have Heroku app URL configured against an app name
Similarly what we do with git remote add ( we pass git URL as a destination for push/pulling of code )
that how our git know which repo/URL to hit (push/pull from )
Heroku also follows the same method/process.
All you have to do is add Heroku app URL (so that ur Heroku command have a reference for app URL )
it will know against which URL you are running your command against
To confirm if remote named Heroku has been set for your app:
git remote -v
if not configured or if you want it for an existing app
heroku git:remote -a app_name
it's a way to link your folder to the Heroku app
The Heroku recommended way:
heroku git:remote -a my-heroku-app-id -r what-i-want-to-call-it
Source: https://devcenter.heroku.com/articles/git
Run this command from an app folder or specify which app to use with --app APP
The other answers address the first part of that statement, it is perfectly acceptable to run heroku commands in any directory. For example I have a customer facing front end project /front-end and a rails based /back-end project. I often work in the /front-end directory and if I have to connect to the production database I'll run heroku run rails c -a back-end. After I exit irb then I'm back in my desired directory.
