Did you run with --trace?

You can try to provide the absolute path instead of default '.' in you call to workflow_diagram like

Workflow::Draw::workflow_diagram(ENV['MODEL'].constantize, path: '/my/absolute/path/with/write/permissions'

The error message is very explicit:

Error: Could not open "'/vagrant/tmp/orders_workflow.png'" for writing : No such file or directory

Did you try touch /vagrant/tmp/orders_workflow.png ?

Did you try running dot manually? The call is in the array: /usr/bin/dot -q1 .... But first ensure the temporary dot file like "/tmp/graphviz.rb20140724-7173-mq9962" in your example exists.

Background:

recent versions of workflow use the graphviz gem.
The gem calls the dot diagramming tool you installed on your machine.

You will have to debug this (not complicated) interaction.

warmwater · 2014-08-18T08:58:43Z

I encounter same error and same --trace messages when I was using JRuby 1.7.13 on Windows 7 x64

@warmwater Nice that you can reproduce it (I can't)! What is the result of your debugging then?

I have also tested on Ubuntu 12.04 server, ruby 1.9.3p545, rails 4.1.4...got same error messages

geekq · 2014-08-18T09:54:30Z

Can you please debug (find the cause)? S. my comments #110 (comment) for the inspiration ;-)

warmwater · 2014-08-18T10:41:13Z

Hi @geekq

i created the temp file and png file first in Ubuntu
touch /tmp/graphviz.xxxxxxx
touch ./taro-workflow.png
then executed:
/usr/bin/dot -q1 -Tpng -o'./taro-workflow.png' /tmp/graphviz.xxxxxxx

it shows no error message and png file is empty

got same result on windows 7 (Jruby)

mbhnyc · 2014-08-20T22:53:43Z

Seeing this same issue on OSX 10.9.4 as well :(

ivanoblomov · 2014-08-27T18:20:16Z

The only way I got it to work was to run it from console:

require 'workflow/draw'; Workflow::Draw::workflow_diagram Order

You'll get the same error, but so long as you don't quit console, you'll have access to the temporary Graphviz command file.

Concatenate the command-line array and run it in another shell to generate the diagram.

ivanoblomov · 2014-08-27T22:06:58Z

Note that Mavericks may be complicating things as well. The Graphviz folks recommend upgrading to 2.39...

http://www.graphviz.org/content/dot-jpeg-and-mavericks

ivanoblomov · 2014-08-28T21:22:55Z

Ignore the comment about Graphviz 2.39; 2.38.0 behaves identically.

warmwater · 2014-10-13T04:04:59Z

hi @geekq

Sorry for late reply

I tried the method in #110 (comment) , I am able to touch /tmp and output folder, I have also tried the absolute path, However it still doesn't work.

No tmp file nor output file has exported,

jkingsbery · 2015-02-11T18:50:51Z

Also seeing this on MacOS OX 10.9.5, workflow version 1.1. I tried the absolute path, that didn't work.

There error message is a bit confusing: is it trying to write to './orders_workflow.png' or ./orders_workflow.png, with quotes or without the single quotes?

jkingsbery · 2015-02-11T23:11:08Z

For anyone who cares, patching line 69 of draw.rb to be graph.output options[:format] => "#{filename}" seems to fix the issue. This is the same change proposed by nyon's PR.

geekq · 2015-02-12T14:49:37Z

I do not use Mac. @jkingsbery can you please test, if the removing single quotes (commit f174a83) helped now?

geekq · 2015-02-12T14:54:03Z

Fails on linux https://travis-ci.org/geekq/workflow/jobs/50497167
Will revert.

geekq · 2015-02-12T14:56:52Z

Will get rid of graph-viz gem. Without that graphviz generation worked reliably for years.

hmaack · 2015-03-03T14:42:15Z

👍

loofel · 2016-03-10T21:11:04Z

applying the fix suggested by @jkingsbery (draw.rb:69 change '#{filename}' to "#{filename}") and changing draw.rb:4 to gem 'ruby-graphviz'#, '~> 1.0.0' worked for me on ubuntu trusty

rjo · 2017-04-21T04:53:42Z

has there been any movement on this? I just ran into it again on a new project and can't even remember how i got around it last time.

mbhnyc · 2017-04-24T16:29:06Z

not that got checked in i don't think :(

rogerhu · 2017-07-18T05:12:17Z

See: #203

rogerhu · 2017-07-18T05:13:37Z

Looks like this fix was patched and then reverted...

rogerhu · 2017-07-18T05:15:32Z

I'm using ruby-graphviz (1.2.3) so it seems like there are tests that need be to fixed for this patch to go in?

nyon mentioned this issue Nov 5, 2014

fixes issue #110 and #128, adding possible_events method #132
