wicked pdf not displaying amazon s3 images - amazon-web-services

A very strange thing has happended to my app recently and not sure what has changed? wicked pdf is not longer displaying my https:// images from my amazon s3 server. I am using the images with the src= "https://pathtoimage.png" and they were displaying just find before.
The displaying of images is not working locally or on heroku. On my production server, the pdf rendering is not working as well and creating a bunch of blank white pages.
I am using the gem
gem 'wkhtmltopdf-binary'
gem 'wicked_pdf'

This is the fork of the wkmtltopdf-binary that worked for me: https://github.com/pallymore/wkhtmltopdf-binary.
Insert the following lines in your Gemfile:
gem 'wkhtmltopdf-binary-edge', '~> 0.12.2.1'

Last 2 days i am facing the same problem. I have the version of wkhtmltopdf is 0.9.6. I have upgraded the version to 0.9.9. Now it's works fine.
I feel amazon might change something.

It seems that the version of wkhtmltopdf that comes bundled with the wkhtmltopdf-binary, 0.9.9 has this problem. Uninstalling the gem and then installing a newer binary such as 0.12.2.1 solved this issue for me.
I'm on OS X so I installed it with homebrew but there are binaries for other systems on wkhtmltopdf.org
Here's how to install a newer version of wkhtmltopdf with homebrew:
brew install cask
brew cask install wkhtmltopdf

Installation vs Gem - Paperclip and ImageMagick

I am trying to install Paperclip on my Rails Project but it seems I need ImageMagick installed too too.
I thought first ImageMagick was a gem to install but it is actually a piece of software.
My question is :
Why not a gem ?
And as it is a piece of software, will I get into trouble finding an hosting service that has ImageMagick installed too on their servers?
ImageMagick is a command line utility for modifying images. Paperclip uses it for resizing/thumbnailing image uploads. If your hosting service gives you SSH access, you should be able to install it on your server(s).
Propably NO.
I use Digitalocean for my projects and you can install imagemagick simple via their ssh. I suppose this happens to any vps service.

rails tutorial could not locate gem file when bundle install

Hi I'm new to Ruby on rails and doing the tutorial on railstutorial.org, I'm stuck on the the first chapter about bundler install.I updated my gem file to what version I want them on but when I go to hello_app directory and type bundle install in in my shell I get a "couldn't find gem file". I type LS or ls in the hello_app directory and gemfile.rb shows up. what am i doing wrong? Ive done a search on this topic for 2 hours I have not found a solution. I have rails 4.2.1 installed but i also installed 4.2.0 because the book calls for this version, don't know if thats the cause.
If you installed rails correctly before creating a new rails app, I'm not sure you'll even need to update your gems with the bundle install
I found out what was wrong. I had saved the Gemfile in a .rb extension thinking it was suppose to be a ruby file. thats why it couldn't find the Gemfile. how I found out was just restarting the rails project from the beginning and do it step by step. I found the original Gemfile didn't have the .rb file extension, so when I tried bundle install it worked. thank for the reply #Mba Uchenna.

PG pg_ext load error in rails

I recently updated to rails 4.1.6 and ruby 2.1.3p242. I also updated all gems on my system. After creating a new app, I keep getting a pg_ext load file error on running the server. I'm on windows 8 x64 with PostgreSQL 9.3. The pg gem was working fine under my previous RoR installation which was rails 3.2 and ruby 1.9.3.
Under the gem's installation directory, I've a 2.0/pg_ext.so file. I tried renaming the folder to 2.1 and ran the server. The result was the same. I assume it's cause Ruby doesn't allow to Require a .so file. Below is the screenshot of the error:
Any help would be really appreciated. Thanks!
Posted question on the official Gem page:
https://bitbucket.org/ged/ruby-pg/issue/192/pg_ext-load-error
As per the suggestion, I installed the pre-version of the next release. That gave me another error which was solved using:
https://github.com/tzinfo/tzinfo/wiki/Resolving-TZInfo::DataSourceNotFound-Errors
TZInfo::DataSourceNotFound error starting Rails v4.1.0 server on Windows
Posting the answer to help people facing similar problems in the future.
1) In the command line enter:
gem install pg --pre
gem list pg
2) In the Gemfile set the gem to the newly installed version:
gem 'pg', '~> 0.18.2'

bundle cannot find the global shared gem in nginx/passenger

The passenger reports error that the gem json cannot be found. While other gems can be found because they are installed by bundle install. However, json was default installation by ruby 2.1.1.
And it is wired that bundle shows json has been deleted.
$ bundle show json
The gem json has been deleted. It was installed at:
/home/canoe/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/json-1.8.1
But gem can still find it on system.
$ gem list json
json (1.8.1)
And json is installed at this location /home/canoe/.rbenv/versions/2.1.1/lib/ruby/2.1.0/json.rb.
I don't use cap while deploying the rails4.1 application, so this solution doesn't work for me.
I don't want to package everything into somewhere, instead to use all current installed gems in the gemsets.
So, how to make bundle use system default gems in nginx passenger?
I encountered the same issue, but following post helped me: fusion passenger issue with json gem when running on nginx
Maybe you are also using some ruby version control tool. As I'm using RVM.
According to the comment in above post. passenger_ruby need to be pointed to the RVM wrapper folder.
eg:
passenger_ruby /usr/local/rvm/wrappers/ruby-2.0.0-p481/ruby;

Get 'best-in-place' gem for rails4 from github w/o internet

I got a very limited internet connection on my office laptop and I want to install the 'best-in-place' gem. Since I use rails 4 I need to get the gem from github as far as I understood various threads. But I cant run bundle install with access outside of my local system.
Is it still possible to install that gem somehow? I already downloaded the folder form github and put it into my ruby but its not working that easy.
Best regards!
Edit: If thats not possible, does anyone of you uses an alternative gem with similar functions?
You can always clone it (or download it, as you have) and then access it later.
Let's say that you downloaded it to: /home/user3665315/workspace/best_in_place
Then, in your Gemfile you can access it locally with the :path option
# Gemfile
gem "best_in_place", path: "/home/user3665315/workspace/best_in_place"
then run
bundle install
and that's it, you have it working locally
