This library can read and write PNG files. It is written in pure Ruby for maximum portability. Let me rephrase: it does NOT require RMagick or any other memory leaking image library.

QUESTION
I'm trying to deploy my Rails 5.0 on heroku after a bundle update. I'm blocked by an issue on assets:precompile

It was not directly linked to assets generation, but the probleme was indicated at the first error line in the logs :

I postes this question because I didn't find any related answer on stackoverflow. I did everything. I will explain what I have tried.
When I start the Rails server using rails s, I get the following output:
ANSWER
Answered 2019-Jul-03 at 12:33The root of the problem seems to be bundler. What operating system and Ruby version are you using? It may be a problem with old OpenSSL library, so you can not install bundler and everything after it.
If you are using jRuby (your gem list output tells so), your problem seems to be the same as described in link. And there is a solution as well.
Maybe you forgot to set 2.1.2 version of ruby as global? (rbenv set global 2.1.2)

QUESTION
I tried bundle install as below, but without any success.
I tried a lot of method which I found here and there:
- I tried with sudo and without,
- I tried bundle update,
- I deleted Gemfile.lock
- I installed manually json 1.8.6. but it only want to use 1.8.0. and quits installing the other gems, when it doesn't find that.
Note, that I am relatively new at Ruby, thus it may be some straightforward solution. For example I should need explain bundle somehow to use 1.8.6., but I have no clue how to do it.
...ANSWER
Answered 2019-Feb-05 at 15:54Try running bundle update json to force update the json gem. If that doesn't work, you can run gem clean, delete your Gemfile.lock and run everything again.
Edit: It looks like your bundler version isn't compatible with your version of rails. You can try to downgrade bundler by running:
gem install bundler --version '1.14.6'gem uninstall bundler --version '2.0.1'
Also, is this a new project? If so, you should consider using rails 5. Rails 3 is close to being three major versions behind with the release of rails 6 not too far away. It would help avoid a lot of these gem issues as well.

QUESTION
I have a rails app and since a few hours I get empty pages when accessing some of the locations urls inside activeadmin:
/admin/orders
In turn all other pages seem to work fine. For example:
/users/orders/33(Order detail)/products/news/categories
This is the HTTP Response for mydomain.com/admin/orders:

- Update ActiveAdmin fom 1.0 to 1.1 (Did not work in both cases)
- Update Rails from 4.4.2 to 4.2.10
- Restart the server (the actual machine)
ANSWER
Answered 2017-Oct-06 at 18:41I would guess you have bad/unexpected order data in production. Review the data directly in MySQL, visit the view pages for each of the orders. Post here the orders index definition if practical.

QUESTION
Running grunt serve which use to work I'm having this error message.
Running "compass:server" (compass) task
Warning: Command failed: compass --version
/usr/lib/ruby/gems/2.4.0/gems/bundler-1.13.7/lib/bundler/definition.rb:179:in `rescue in specs': Your bundle is locked to chunky_png (1.3.4), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that means the author of chunky_png (1.3.4) has removed it. You'll need to update your bundle to a different version of chunky_png (1.3.4) that hasn't been removed in order to install. (Bundler::GemNotFound)

So on side I ran a compass --version and I obtain the same error Your bundle is locked to chunky_png (1.3.4), etc.
Trying to bundle install seems a bit useless...
$ bundle install
Could not locate Gemfile or .bundle/ directory
So I tried to reinstall ruby-compass because which compass sent me to /usr/bin/compass which is the one set by ruby-compass AUR package.
that did'nt solved the problem. Any idea around ?

Install chunky_png
On a UNIX-like operating system, using your system’s package manager is easiest. However, the packaged Ruby version may not be the newest one. There is also an installer for Windows. Managers help you to switch between multiple Ruby versions on your system. Installers can be used to install a specific or multiple Ruby versions. Please refer ruby-lang.org for more information.
