Hi all,

I want to love capistrano and I’m so close.

My error is occuring while running the update\_code task… (apologies  
for the shell spew)

* * *

- executing “rm -rf  
/home/henster29/sites/glitter/releases/20060316143447/log  
/home/henster29/sites/glitter/releases/20060316143447/public/system  
&&\n ln -nfs /home/henster29/sites/glitter/shared/log  
/home/henster29/sites/glitter/releases/20060316143447/log &&\n ln  
-nfs /home/henster29/sites/glitter/shared/system  
/home/henster29/sites/glitter/releases/20060316143447/public/system”  
servers: [“[aidlife.textdriven.com](http://aidlife.textdriven.com)”]  
[[aidlife.textdriven.com](http://aidlife.textdriven.com)] executing command  
\*\* [out :: [aidlife.textdriven.com](http://aidlife.textdriven.com)] ln:  
/home/henster29/sites/glitter/releases/20060316143447/public/system:  
No such file or directory  
command finished

* * *

Ah, so its trying to make a symbolic link to a dir that doesnt exist…  
I checked the gems/capistrano-1.1.0/lib/capistrano/recipes/standard.rb  
which seems to be the source and found this…

* * *

task :update\_code, :roles =\> [:app, :db, :web] do  
on\_rollback { delete release\_path, :recursive =\> true }

source.checkout(self)

run \<\<-CMD  
rm -rf #{release\_path}/log #{release\_path}/public/system &&  
ln -nfs #{shared\_path}/log #{release\_path}/log &&  
ln -nfs #{shared\_path}/system #{release\_path}/public/system  
CMD  
end

* * *

Which looks like (to me) that it blows away  
#{release\_path}/public/system and then tries to make a link in there.

I must be talking crap since this works for everyone else… Any ideas?

Thanks  
-henry

Henry,

Did you set up your machines using the ‘setup’ task, or did you build  
the directories manually?

The directory structure ought to look like this:

/deploy\_to  
/deploy\_to/releases  
/deploy\_to/releases/…  
/deploy\_to/shared  
/deploy\_to/shared/log  
/deploy\_to/shared/system  
/deploy\_to/current -\> /deploy\_to/releases/…

Thanks for the help guys, you led me down the right track.

I was trying to deploy a single file,“test.txt”, to see if I could get  
it to work… rather than a whole rails app.  
/deploy\_to/releases/public isnt made in setup but rather checked out  
from your repos. So public wasnt there… Oops.

It might be nice to have /deploy\_to/releases/public created during  
setup… but I may be in the minority using full blown capistrano to  
upload a text file 😉

Shell spew is helpful. Give us more!

If you want to trouble shoot this, change the rm -rf to rm -r. Then if  
the #{release\_path}/log or #{release\_path}/public/system do not exist,  
you will get an error. The -f option causes rm not to complain about  
directories that don’t exist, in addition to forcing removal of files  
that have restrictive permissions.

As Jamis points out in a parallel response, if you run the setup tasks  
these directories should have been created, but is possible that they  
don’t.
