I typed rails s to run my server then I got this:
Warning: Running `gem pristine --all` to regenerate your installed gemspecs (and deleting then reinstalling your bundle if you use bundle --path) will improve the startup performance of Spring.
Could not find gem 'pg' in any of the gem sources listed in your Gemfile or available on this machine.
Run `bundle install` to install missing gems.
So I did bundle install then I got this:
An error occurred while installing pg (0.18.4), and Bundler cannot continue.
Make sure that `gem install pg -v '0.18.4'` succeeds before bundling.
I did brew install postgres to solve this but it still didn't work. Also I put 'gem pg '0.18.4' on Gemfile then did bundle install but still didn't work.
I need your help!

Have you tried to clean and rebuild you gem bundle? You can do it with command bundle clean --force and then bundle install again.
Please be advised: the clean command will remove all your gems.
Post back the result of such commands if you decide to run them.

I'm currently working on a Rails 5.2 application. In the Dockerfile I'm using ruby:2.5-alpine. when running the following code

Any help?
I don't understand docker with proficiency. But, all times that i had this error with ruby, is because on the situation i'ved been send a file in verification. The solution for those issues are send the file path instead the file.
When trying to run bundle install on i receive the following exception:
$ bundle install
Fetching gem metadata from https://rubygems.org/..........
Fetching gem metadata from https://rubygems.org/..
Could not find gem 'minitest/autorun x64-mingw32' in any of the gem sources
listed in your Gemfile.
I was originally trying to run bundle exec rake, which suggests the same issue with gem 'minitest/autorun x64-mingw32'. Running them with rake test works fine; hence, I think I've done something wrong with bundler related to my OS (windows 7 x64). The install works properly without this package. I also tried using unit/test with the same result.
Ruby version is 2.4.4.
Gemfile:
source "https://rubygems.org"
gemspec
gem 'json', '~> 2.1.0', '>= 2.0.4'
gem 'addressable', '~> 2.5.2', '>= 2.5.2'
gem 'mongo', '~> 2.5.1', '>= 2.5.1'
group :test do
gem 'rake'
gem 'minitest/autorun'
end
Do I need to specify the platform or some other variable so that bundle looks for the right version of the gem on rubygems?
Any help would be much appreciated.
Using gem install, how can I add a gem to only one particular environment, like development or test or production? As seen below:
group :development do
gem 'web-console', '>= 3.3.0'
end
You can't do this via gem as the Gemfile is used by Bundler. However, since Bundler version 1.15.0 you can use bundle add:
bundle add web-console --group development
This will then add the following line to your Gemfile:
gem "web-console", "~> 3.6", :group => [:development]
I'm using ruby 1.9.3p194 and bundler 1.1.4
In my Gemfile I have this:
group :production do
gem 'thin', '1.4.1'
end
When I run $ rails s, bundler keeps complains:
Could not find gem 'thin (>= 1.4.1) ruby' in the gems available on this machine.
Run `bundle install` to install missing gems.
I'm running under development environment, so shouldn't it NOT care if it is installed or not? Dose bundler force you to install ALL the gems when running $ rails s?
I also tried the group:test, same thing happens. That doesn't really make sense to me, can anyone help?
my gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.6'
gem 'mysql2'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
end
gem 'jquery-rails'
group :production do
gem 'thin', '1.4.1'
end
gem 'devise', '2.1.2'
gem 'cancan', '1.6.8'
gem 'will_paginate', '3.0.3'
Possibly the problem is that you are running rails s, while you need to run bundle exec rails s. If you precede a command with bundle exec, it is executed within the context of the bundle. All the gems available to bundler are then available to the command.
By default, gems from bundles are installed in the global gem directory. This can produce confusing results when you don't prepend bundle exec to a command: imagine you have both rails 3.1 and rails 3.2 in your global gems and your Gemfile mentions 3.1. Then you will still call the executable from rails 3.2 when you simply say rails on the command line.
Now of course thin could only be missing if it wasn't installed with the global gems. Assuming you've used the --path option to bundler at least once, your gems have been installed to the path specified there and not to the global repository. After using --path, you must specify bundle exec, otherwise gems simply won't be found at all.
I am following along the Ruby on Rails Tutorial and have gotten somewhat confused in the testing section, in particular - 3.6.2 - Automated tests with Guard
As per the tutorial's instructions for deployment to Heroku, I've switched over to Postgresql and removed sqlite3 from my gemfile and did a bundle install to update.
However, once I run
bundle exec guard
I receive the message:
/Users/username/.rvm/gems/ruby-1.9.3-p125#global/gems/bundler-1.1.3/lib/bundler/rubygems_integration.rb:147:in block in replace_gem': Please install the sqlite3 adapter:gem install activerecord-sqlite3-adapter` (sqlite3 is not part of the bundle. Add it to Gemfile.) (LoadError)
I'm confused why I need this as sqlite3 has been removed from my environment?
My Gemfile is as follows:
source 'https://rubygems.org'
gem 'rails', '3.2.3'
gem 'pg', '0.12.2'
group :development, :test do
gem 'rspec-rails', '2.9.0'
gem 'guard-rspec', '0.5.5'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.0'
group :test do
gem 'rspec-rails', '2.9.0'
gem 'capybara', '1.1.2'
gem 'rb-fsevent', :require => false
gem 'growl', '1.0.3'
gem 'spork', '0.9.0'
end
I'm a bit confused because the Gemfile in the tutorial shows sqlite3 again even though it was removed in the previous section of the tutorial.
Update your database config file to use postgresql adapter:
