chef - How to install ClamAV using Ruby script with configuration in same script? -

i using amazon opsworks , struggling working through single script, have created script named clamav.rb. content of script is:

yum_package 'clamav'   action :install end  yum_package 'clamav-update'   action :install end  file_names = ['/etc/freshclam.conf']  file_names.each |file_name|  text = file.read(file_name)   replace = text.gsub("example", "#example")    # merely print contents of file, use:    puts replace    # write changes file, use:    file.open(file_name, "w") {|file| file.puts replace }  end  execute "run freshclam"    command "/usr/bin/freshclam"  end 

when execute above script stuck error:

[2016-08-01t13:02:36+00:00] error: running exception handlers [2016-08-01t13:02:36+00:00] error: exception handlers complete [2016-08-01t13:02:36+00:00] fatal: stacktrace dumped /var/lib/aws/opsworks/cache.stage2/chef-stacktrace.out [2016-08-01t13:02:36+00:00] error: no such file or directory - /etc/freshclam.conf [2016-08-01t13:02:36+00:00] fatal: chef::exceptions::childconvergeerror: chef run process exited unsuccessfully (exit code 1) 

but when divide script in 2 parts run well, creating separate script yum packages , separate configuration change.

you're being bitten chef's two-pass loading model. @ point in code, package hasn't been installed yet. check out https://coderanger.net/two-pass/ more details on that, fix actual problem, use line cookbook has resources kind of search , replace in files, handle sequencing correctly you.
