Guard::Spork failed to achieve its <start>, exception was ...

[RaimundSchramm]

Hi there,

i am not sure if it is an issue and if it is i don't know to wich technology it belongs. So maybe this is of some help otherwise sorry for posting and delete.

Today i wanted to speed up my Integration testing as recommanded with Capybara and Poltergeist using PhantomJs. I already had a setup test suite in place with a usual technology stack like guard-spork, spork-rails, rspec-rails, jasminrice, capybara, factory_girl_rails and dependencies. All is setup as usual on up to date Ubuntu 12.04, with all needed system libraries, rvm, ruby 1.9.3 and rails 3.2.x.

Executing 'bundle exec guard' throws:

So i tried downgrading childprocess to 0.3.6 and it seems to work for me right now.

Have a nice weekend.

[mogria]

The same issue here on Ubuntu 12.10.
Downgrading to childprocess 0.3.6 worked for me too

[thibaudgg]

Ok, have you already open an issue on childprocess?

[RaimundSchramm]

Hi Thibaud,

No, i didn't. Will you do it? Maybe you can describe more precisely than me ;) .

cheers

[darokel]

Hi, getting this same error on OSX. Weird, I have another app with the same test stack and that loads up fine but on my new app, I get this exception.

[darokel]

Mogria's solution removed the exception. Cheers, seems to be an error with childprocess 0.3.7

[buholoco]

Same as darokel
Mogria's solution (downgraded childprocess to 0.3.6) removed the exception. Cheers, seems to be an error with childprocess 0.3.7

[thibaudgg]

Can you try guard-spork from master branch to see if it's fixed? Thanks!

[RaimundSchramm]

Hi,

so i did upgrade only childprocess to verify the error is still there. Then i did bundle update for guard-spork only which updated it and all dependencies (not sure if that was what you meant).

With the most recent gems in place the error is gone.

Thx for the effort : )

[thibaudgg]

@RaimundSchramm with gem 'guard-spork', github: 'guard/guard-spork' in your Gemfile right? (just to be sure)

[RaimundSchramm]

Hi Thibaud,

No, at first i just did a normal bundle update guard-spork with gem 'guard-spork' which installed version 1.4.1.

I just tried gem 'guard-spork', github: 'guard/guard-spork' as you asked and it works as well.
(Is it enough to update the entries in the Gemfile and bundle install or do i have to do something else?)

cheers

[thibaudgg]

I should be ok, I'll release 1.4.2 when rubygems will be back!

[thibaudgg]

1.4.2 released!

[CoolJorcz]

I'm new to programming. Can someone help explain to me how to downgrade ChildProcess?

[mogria]

replace your current line in the Gemfile which installs the child process gem with the following one

gem 'childprocess', '0.3.6'

[CoolJorcz]

Hi Mogria,

My GemFile doesn't have ChildProcess. Would it be included in another gem? Here are the contents:

gem 'rails', '3.2.12'

group :development, :test do
gem 'sqlite3', '1.3.5'
gem 'rspec-rails', '2.11.0'
gem 'guard-rspec', '1.2.1'
gem 'guard-spork', '1.2.0'
gem 'spork', '0.9.2'
end

Gems used only for assets and not required

in production environments by default.

group :assets do
gem 'sass-rails', '3.2.5'
gem 'coffee-rails', '3.2.2'
gem 'uglifier', '1.2.3'
end

gem 'jquery-rails', '2.0.2'

Test gems on Macintosh OS X

group :test do
gem 'capybara', '1.1.2'
gem 'rb-fsevent', '0.9.1', :require => false
gem 'growl', '1.0.3'
end

group :production do
gem 'pg', '0.12.2'
end

[mogria]

then simply add the line to the gemfile

and then run bundle install again

[CoolJorcz]

That did it! Thank you!

[jeff-romine]

Apparently this isn't fixed yet since I ran into it today. Thank's for solving the problem for me.

[thibaudgg]

@jeff-romine are you using the last version of guard, guard-spork, spork and bundle exec ...? Please also read the https://github.com/guard/guard/blob/master/CONTRIBUTING.md guide to be sure to give all useful info. Thanks

[meowsus]

Adding gem "childprocess", "0.3.6" to my Gemfile worked for me!

[stellorior]

same problem today, so I tried to downgrade to 0.3.6 and this is what I got:
You have requested:
childprocess = 0.3.6

The bundle currently has childprocess locked at 0.3.9.
Try running bundle update childprocess
--> I did "bundle update childprocess" and now it seems to work fine.

[ThreeStar]

I also have caught this issue,how to downgrade the version from 0.3.9 to 0.3.6?

[thibaudgg]

@ThreeStar Add gem 'childprocess', '0.3.6' to your Gemfile and run bundle update childprocess

[ThreeStar]

@thibaudgg Thanks,guy~ It works.

[trentscott2]

Thanks! This was helpful. I followed the comments from @thibaudgg:

Add gem 'childprocess', '0.3.6' to your Gemfile and run bundle update childprocess.

[shuke0327]

I meet the same problem, and fixed it by upgrade gem "guard-spork" from 1.2.0 to 1.4.2, and it works well.

the childprocess gem version is 0.3.9
