I suppose the bundling is going to happen on the heroku servers anyway. What is the purpose of doing it on the local machine?
bundle install
This ensures that all gems specified in Gemfile, together with their dependencies, are available for your application. Running bundle install also generates a Gemfile.lock file, which should be added to your git repository. Gemfile.lock ensures that your deployed versions of gems on Heroku match the version installed locally on your development machine.
If the platforms section of your Gemfile contains Windows entries,
such as mswin or mingw, then the Gemfile.lock file will be ignored.
Heroku also uses that file to resolve and install your application dependencies automatically. All you need to do is to push it.

This will update your Gemfile.lock, that heroku uses to install all your gems on your virtual server. The Gemfile.lock contains all information about your gems and their respective versions.
It has two purposes :
It ensures you that, on your machine, you have all the dependencies for your application satisfied;
It updates the Gemfile.lock file. While the Gemfile has the list of your app's gems, the Gemfile.lock has a more.. "detailed" version of it, with the gem's own dependencies, their version constraints... It basically is a snapshot of your project dependencies. This way, your app in production will run with the exact same versions of third-party code as do your code in local.
This ensures that all gems specified in Gemfile, together with their dependencies, are available for your application. Running bundle install also generates a Gemfile.lock file, which should be added to your git repository. Gemfile.lock ensures that your deployed versions of gems on Heroku match the version installed locally on your development machine.

I have a problem working with a remote repository. I do git clone <URL> just fine.
The problem is when I run bundle. I get loads of errors. Those errors are fixed by using bundle update, as it installs all the gems and then I can run everything fine. The problem is that my Gemfile.lock file gets changed and it comes as a file to be committed in the git repository (which it should not, because it will mess up the remote repository's Gemfile.lock file). Now I cannot push Gemfile .lock to the remote repository as it will break everything. But the strange part was that this Gemfile.lock is not included in the .gitignore file... So any ideas how I can overcome this or could somebody explain to me what exactly is going on ?
When you run bundle, bundler will use the gems that are listed in the Gemfile.lock. bundle update updates the Gemfile.lock to get the latest of all gems listed in the Gemfile while still satisfying all dependencies.
You can run bundle update on a particular gem as well, which will limit the Gemfile.lock changes to dependencies of said gem.
You need to be a little more clear about which errors you are receiving? Are they dependency related? or are you not able to build a gem with native extensions? or something else? are you using gemsets - if not, that might be useful to prevent gem collisions.
Is there really a problem with Gemfile.lock being committed? Are you a contributor to the repository?
Additionally, bundler gets updated every now and then. You may want to update your version of bundler before running bundle.
gem update bundler
When deploying my Rails App to Linode via Capistrano/Unicorn, when running this command "bundle exec cap deploy:cold" it's giving the error :
The --deployment flag requires a Gemfile.lock. Please make sure you have checked your Gemfile.lock into version control before deploying.

*** [deploy:update_code] rolling back
I've searched around and can't seem to find a solution. Any one know any solutions? How do you check your gemfile.lock into version control
https://github.com/Ruekompa/itcinema.git
After a little while of running running countless commands and attempts, I now notice there is a folder called cached-copy residing in /home/USERNAME/apps/APPNAME, and it contains my app.
UPDATE:
I have fixed everything. I simply rebuilt ubuntu server on linode and started over. This time my deployment worked. Thanks everyone
I have fixed everything. I simply rebuilt ubuntu server on linode and started over. This time my deployment worked. I changed Ubuntu 12.04 to 10.04. Perhaps it was something in my capistrano recipes, for I was piggy backing off of someone else's code that was using 10.04.
Did you add the Gemfile.lock to your repository?
you can add it by
# in your app root dir
git add Gemfile.lock
git commit -m "Added Gemfile.lock to repository"
EDIT
Did you run the following command?
bundle install --deployment
I'm pretty new to bundler and capistrano, and I'm trying to use them together. When I try to deploy, I get the message:
You are trying to install in deployment mode after changing your Gemfile. Run `bundle install' elsewhere and add the updated Gemfile.lock to version control.
I don't know how to satisfy the system that's complaining, and I don't understand why the complaint is coming up because I read in the doc:
If a Gemfile.lock does exist, and you have updated your Gemfile(5),
bundler will use the dependencies in the Gemfile.lock for all gems
that you did not update, but will re-resolve the dependencies of gems
that you did update. You can find more information about this update
process below under CONSERVATIVE UPDATING.
I interpret that to mean that the Bundler can handle the fact that my Gemfile is not whatever it expected. Any help?
Specs: Ruby 1.9.3, Rails 3.2.3, Capistrano 2.12.0, Bundler 1.1.4, Windows 7, deploying to a Posix machine.
Edit: My Gemfile includes logic blocks like the following:
unless RbConfig::CONFIG['host_os'] === 'mingw32'
# gem 'a' ...
end
The error message you're getting regarding Gemfile.lock may be because your Gemfile and Gemfile.lock don't agree with each other. It sounds like you've changed something in your Gemfile since you last ran bundle install (or update). When you bundle install, it updates your Gemfile.lock with any changes you've made to Gemfile.
Make sure you run bundle install locally, and check-in to source control your newly updated Gemfile.lock after that. Then try deploying.
Edit: As recognised in the comments, a conditional in the Gemfile resulted in a valid Gemfile.lock on one platform, invalid on another. Providing a :platform flag for these platform-dependent gems in the Gemfile should solve the asymmetry.
vi .bundle/config
change the BUNDLE_FROZEN option from '1' to '0'
do "bundle install"
OR
run "bundle config"
see if the "frozen" value is true set it to false
bundle config frozen false
Watch out for global Bundler config.
I had a global config on my dev environment in ~/.bundle/config that I did not have in my CI / Production environment that caused the Gemfile.lock that was generated in my dev environment to be different than the one in my CI / Production environment.
In my case I was setting github.https to true in my dev environment but had no such config in my CI / Production environment. This caused the two Gemfile.lock files to be different.
When you see the following...
$ bundle install
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
updated Gemfile.lock to version control.
If this is a development machine, remove the Gemfile freeze
by running `bundle install --no-deployment`.
You have added to the Gemfile:
* source: rubygems repository https://rubygems.org/
* rails (~> 3.2)
. . .
... Then, the problem is most likely that you have outdated .gem files in your vendor/cache directory.
Perhaps, you previously ran $bundle install --deployment which put some "outdated" .gem files in the cache?
In any case, you can get past this error by running: bundle install --no-deployment
That's one of the many great things about Rails... the error messages often tell you exactly what to do to fix the problem.
My specific problem was related to what reported by #JoshPinter, i.e. dev-vs-deploy host discrepancies in the protocol used by bundler to retrieve gems from github.
To make a long story short, all I had to was modify the following Gemfile entry...
gem 'activeadmin', github: 'activeadmin'
...to this secure syntax (see reference):
gem 'activeadmin', git: 'https://github.com/activeadmin/activeadmin.git'
And my deployments are back to normal.
I don't care. This is what I did. It fixed it.
rm -rf .bundle
rm -rf Gemfile.lock
bundle install
The solution for me was slightly different than the others listed here. I was trying to upgrade from sidekiq to sidekiq-pro (which requires bundler 1.7.12+), but I kept getting the "You are trying to install in deployment mode after changing your Gemfile" message from travis-ci
Inspecting the console output of travis-ci revealed that an older version of bundler was being used.
In my case, I had to edit the travis.yml file to add:
before_install:
- gem update bundler
This forced travis-ci to use the latest version of bundler, and made the error message go away.
rm -fr .bundle
Fixed the problem for me.
Another cause of the error:
This is a bit foolish, but i'm sure someone else will make the same mistake.
For Rails 4 Heroku added the gem rails_12factor. If you were using it before they added it, then you'll have these two gems:
gem 'rails_log_stdout', github: 'heroku/rails_log_stdout'
gem 'rails3_serve_static_assets', github: 'heroku/rails3_serve_static_assets'
You have to remove them when you add the new one. (they're included). I think you can get away with it until you touch them lines in your gem file, then Heroku notices the duplication and cries out with the above error.
good luck with Rails 4.
After this command, you can do your normal bundle install again:
bundle install --no-deployment
I ran into something similar before. One way to fix it, I think, but may take more space on your server than you want, is to run
bundle install --deployment
and then try to deploy. This does something like install all of your gems into the vendor folder, which I believe is generally good to avoid... but will still probably work. My app used to behave like this, my solution was removing exact versions to download from in my Gemfile, and then rebundling and deploying.
gem 'rails_admin', :git => 'git://github.com/sferik/rails_admin.git', :branch => 'master'
to
gem 'rails_admin'
Or you can do what it suggests, and Git your project off the production server onto a local machine, bundle it, and then repush onto your server. This solution might not be 100% correct but some of it worked for me... just thought I'd share. Goodluck
In our case we were using a feature that wasn't available in an old version of bundler which ran on our production machine. Therefore it was enough to upgrade bundler, i.e. do a gem update bundler.
This might be a dangerous idea, but if absolutely must test something in a production deploy environment, you can edit the .bundle/config file
# This value is normally '1'
# Set it to '0'
BUNDLE_FROZEN: '0'
Now invoke bundle, in my case I needed to update a specific gem, so this my command
RAILS_ENV=production bundle update <whatever gem>
You should probably change it back after the update, so things work like you expect, afterwards. Again, this is probably unsupported, and YMMV
This issue can be related to submodules pointing to old versions of code. For me, I resolved this issue by updating my submodules
If you have submodules, try running:
git submodule update --init
bundle install
The error message for the command bundle install in windows 10 (rails v-7) was like
You are trying to install in deployment mode after changing
your Gemfile. Run `bundle install` elsewhere and add the
If this is a development machine, remove the C:/Users/friends/Gemfile freeze
by running `bundle config unset deployment`.
The dependencies in your gemfile changed
You have added to the Gemfile:
* pg
You have deleted from the Gemfile:
* sqlite3 (~> 1.4)
So I did exactly the error message asked me to do. Ran the following command
bundle config unset deployment
And then I again ran `bundle install and then it worked
I ran into this deploying a Nesta app after some gem updates. What worked for me was to delete the Gemfile.lock, run bundle install to re-generate it, and deploy again.
I ran into a similar issue however I did both bundle install and bundle update and Heroku still rejected my push.
I fixed the issue by just deleting Gemfile.lock and then running bundle install again. I then added, committed, and pushed that to my git repo. After that I had no problem pushing to Heroku.
for heroku, you don't have to change the syntax in the Gemfile. you can just add BUNDLE_GITHUB__HTTPS (note the double underscore) as an environment variable and set it to true (in your heroku app's dashboard under the Settings tab in the Config Vars section). this will switch the protocol from git:// to https:// for all such requests.
I had the error message when attempting push to Heroku. I found the following solution fixed.
Git pull origin master
Git status
Git commit
Git push origin master
Git push heroku master
I read a dozen solutions on different resources but didn't find exactly what could help me in this situation
So I did find a solution. Exactly saying i read the error message attentively and there was a sollution: Run bundle install elsewhere. "Elsewhere" was my Cloud9 where i developed my app. So my steps
copy Gemfile and Gemfile.lock from server to local machine with rsync command
insert these two files into my RoR project (i used Cloud9)
open Gemfile and make changes that i want. In my case i added gem 'thin'
in terminal cd to my app on Cloud9 and run bundle install. in this case you will have a changed version of Gemfile.lock
copy new Gemfile and Gemfile.lock on server using rsync
cd to my app folder and again run bundle install --deployment --without development test
DONE! Wish GOOD luck for all!
As of the time of this writing Bundler support for capistrano defaults to "deployment: true", per
https://github.com/capistrano/bundler
So as opposed to trying to modify the bundle by hand after bundler [via capistrano] has laid it down, you may be able to solve the problem permanently by adding this to your deploy.rb or other Capistrano config file [you can do it just for one stage file as well if necessary]:
set :bundle_config, { deployment: false }
and then deploying again.
You will then notice in the "cap" output the following line [note I am using rvm here but you may not be]
.../rvm ruby-2.7.6#... do bundle config --local deployment false
Why did this stop working all of a sudden?
This is the $1M question, I never had to mess with this, but once I got to an Ubuntu 20.04.05 machine, suddenly, yes. Same cap files, same ruby version, same rails version, same OS version except the minor number.
Did it work?
Did this work for you? Leave me a comment and let me know.
I know that my local machine and Heroku are using the same version of the gem, but I'm wondering if it's possible that Heroku hasn't grabbed the latest bug fix tracked here.
Is it possible that my local machine has a newer delayed_job 3.0.0 gem than Heroku does? The fix was committed on the 12th.
When does Heroku update its gems?
This seems likely because I can send email from my local rails app, but on Heroku, I run into problems detailed in the link above. I'm on the bamboo-mri-1.9.2 stack btw.
It short, it doesn't. If you're using Bundler you're stipulating which versions are used in your Gemfile (which in turn defines version numbers in your Gemfile.lock, both of which should be committed to Git).
If you're not using Bundler, and are still using the .gems file at the root of your project, Heroku will use the most recent it has, unless you define a different version in which case it will use that.
More info can be found here: http://devcenter.heroku.com/articles/gems
You should be able to specify a git repository in your Gemfile.
e.g.,
gem "delayed_job", :git => "git://github.com/collectiveidea/delayed_job.git", :ref => "80ca31f9eb"
using the commit with the fix.
(edit: wrong git repo, whoops.)
