Question

Paperclip image uploads in Rails - Paperclip::CommandNotFoundError

Answer 1

+4 A:

You can install ImageMagick on your machine. These problem generates because it will not find some methods.

To check ImageMagick is installed on your machine is simply run 'convert' command on terminal.

hi, thanks for your reply. yes I have ImageMagick installed on my machine. When I run the 'convert' command in the terminal it runs fine. any other ideas? it's clearly the path, but I have no idea how to change it.

ah, but if I run 'identify' from the command line it also runs fine no matter what folder I run it from, does this mean there is another problem?

Install following packeges for working with imagemagick

1) apt-get install imagemagick.
2) apt-get install libmagickwand-dev
3) gem install rmagick

I think you are missing second one.

gem install rmagickBuilding native extensions. This could take a while...Successfully installed rmagick-2.13.11 gem installedThanks! Just ran all the above. Does that mean rmagick was actually not installed?

apt-get install imagemagick should be enough

Answer 3

+3 A:

If you are hosting your application with Passenger, keep in mind that Passenger does not have the same $PATH variable as your logged in user. A good way to check whether Passenger can see the ImageMagick commands is to add this to one of your erb templates:

<%= `which convert` %>
<%= `echo $PATH` %>

and to compare the results with running the same commands in your terminal. Another possibility is ImageMagick can't find the libs it needs. In this case, you may need to export another variable to let ImageMagick know where the libs are:

# my config/environments/development.rb
Paperclip.options[:command_path] = "DYLD_LIBRARY_PATH='/Users/jch/Library/ImageMagick-6.6.3/lib' /Users/jch/Library/ImageMagick-6.6.3/bin"

Hope that helps -jerry

by the same token, you can just type in shell: heroku console %x{convert -version}+%x{which convert}

make sure you restart the server, after adding (or changing) the Paperclip.options[:command_path] to the environments/development.rb
