"Could not find concurrent-ruby-1.1.7 in any of the sources" when deploy rails with capistrano

I saw a lot of similar questions here, but nothing of provided advises has helped. Every time I run cap production deploy I got error:

How I solved it:

Go to server command line
As we can see in error log, the last command before error appears was:

Command: cd /home/deploy/project/releases/20201018151933 && ( export RAILS_ENV="production" RBENV_ROOT="$HOME/.rbenv" RBENV_VERSION="2.6.5" ; RBENV_ROOT=$HOME/.rbenv RBENV_VERSION=2.6.5 $HOME/.rbenv/shims/bundle exec bundle check )

So we go to our folder:

cd /home/deploy/project/releases/20201018151933

and run there command:

export RAILS_ENV="production" RBENV_ROOT="$HOME/.rbenv" RBENV_VERSION="2.6.5" ; RBENV_ROOT=$HOME/.rbenv RBENV_VERSION=2.6.5 $HOME/.rbenv/shims/bundle exec bundle check

After that we see same error:

Could not find concurrent-ruby-1.1.7 in any of the sources. Run 'bundle install' to install missing gems.

In same folder run bundle install and after gem installed we can out of server command line.
Run cap production deploy and everything is gonna be fine.

I still don't know what is the root problem of this error, and how to fix it permanently, but this works for me. I hope it will be useful for anyone else.

How can I convert a picture with any color and form to its shape? As an example I attached an input image and desired output. I need to make this conversion with ruby and ruby-vips gem. Generally speaking, I need to fill anything that is not alpha channel with single color.

You can use [ ] to get bands out of an image. Your image is RGBA, so 0, 1 and 2 are R, G and B, and 3 is A.

As far as I get you want to push feature branch onto Heroku. Builds works only with master branch, so you want to do smth like this:

git push heroku sqlite_to_pg:master

Support

There are full API docs for ruby-vips on rubydoc. This sometimes has issues updating, so we have a copy on the gh-pages for this site as well, which should always work. See the Vips section in the docs for a tutorial introduction with examples. The libvips reference manual has a complete explanation of every method. The example/ directory has some simple example programs.
