I’m trying to create a zip file, but I’m getting an error saying the  
file doesn’t exist, but it exists, as shown in the code.

Any clues ?

I think the permissions are OK, as everyboday can read it …

maybe there’s another way to create a zip file …

thanks,

r.

require “rubygems”  
require ‘zip/zip’  
require ‘zip/zipfilesystem’

file\_path =  
“/Users/montx/Documents/Ruby/codi/scanns/download/bs\_promotors/masivo\_prestamos\_20090521.txt”  
file\_zip="/Users/montx/Documents/Ruby/codi/scanns/download/bs\_promotors/masivo\_prestamos\_20090521.zip"

EXAMPLE\_ZIP=file\_zip  
Zip::ZipFile.open(EXAMPLE\_ZIP, Zip::ZipFile::CREATE) { |zf|

puts “File ready to zip” if File.exists?(file\_path)

puts zf.file.read(file\_path)  
}

output:  
File ready to zip

This is asking to read a file out of the zip file - and as it says,  
there is no such file, as you’ve only just created the empty zip file.

yes, you’re right, I thought it was reading the file and at the same  
time adding it …

In the documentation I have found .add

add(entry, srcPath, &continueOnExistsProc)

and now works …

thanks,
