Here is an issue: serenity-gem works perfectly under ruby 1.8.7 but something happens under ruby 2.0.0p195. While using the same template and ruby-code it gives me the following error:
incompatible character encodings: ASCII-8BIT and UTF-8 (Encoding::CompatibilityError)

This solutions have no effect for me: github, stackoverflow.
My environment: Ubuntu 12.04.2 LTS x86_64 3.2.0-49-generic, rvm 1.21.2.
Fixed by adding string content = content.force_encoding('UTF-8') in /home/michael/.rvm/gems/ruby-2.0.0-p195/gems/serenity-odt-0.2.1/lib/serenity/template.rb
def process context
tmpfiles = []
Zip::ZipFile.open(#template) do |zipfile|
%w(content.xml styles.xml).each do |xml_file|
content = zipfile.read(xml_file)
content = content.force_encoding('UTF-8')
odteruby = OdtEruby.new(XmlReader.new(content))
out = odteruby.evaluate(context)
tmpfiles << (file = Tempfile.new("serenity"))
file << out
file.close
zipfile.replace(xml_file, file.path)
end
end
end
I got the inspiration from here.

here's my code:
> !#usr/bin/ruby
require 'fileutils'
Dir.chdir "/home/john/Documents"
if (Dir.exist?("Photoshoot") === false) then
Dir.mkdir "Photoshoot"
puts "Directory: 'Photoshoot' created"
end
Dir.chdir "/run/user/1000/gvfs"
camdirs = Dir.glob('*')
numcams = camdirs.length
camnum = 0
campath = []
while camnum < numcams do
campath.push("/run/user/1000/gvfs/#{camdirs[camnum]}/DCIM")
puts campath[camnum]
camnum += 1
end
campath.each do |path|
Dir.chdir (path)
foldnum = 0
foldir = Dir.glob('*')
puts foldir
Dir.entries("#{path}/#{foldir[foldnum]}").each do |filename|
filetype = File.extname(filename)
if filetype == ".JPG"
FileUtils.mv("#{path}/#{foldir[foldnum]}/#{filename}", "/home/john/Documents/Photoshoot")
end
foldnum += 1
end
end
puts "#{numcams} cameras detected"
I'm just trying to go into some cameras I have connected and extract all the images into a file but its giving me this error. One of the things that's messing me up is that the images are stored in sub-folders under DCIM. When I just use .entries it gives me the folders the images are in as well as the images.

Any advice? I can't figure out what's wrong.
The reason the path to your files looks strange is because your camera storage has been mounted using FUSE. If you look very closely, you'll see that it is looking for:
/run/user/1000/gvfs/gphoto2:host=%5Busb%3A002%2C021%5D/DCIM//IMG_0092.JPG
You have two forward slashes before the final filename. Try correcting this on line 34 of your app.
If the problem still manifests then it is possible that the user running the operation in Ruby does not have permission to that filesystem or the manner in which the paths are constructed by FUSE is not compatible with Ruby FileUtils.
You can try to run:
cat /run/user/1000/gvfs/gphoto2:host=%5Busb%3A002%2C021%5D/DCIM/IMG_0092.JPG
as the same user that is running the Ruby process to ensure you have read permission to the filesystem.
I'm trying to teach myself some ruby using the app academy tutorials and after doing the readings, installing rvm,rubygems and rspec2 when I even try to run the first most basic code (00_hello) with rake I get the whole error :

I tried to google some of the errors, but with no success. I had previously another error with the rake file using rspec v2 and the current version is 3.0.0, so I had to install the older and I think it might be another setup problem. Thanks if someone can help me or direct me.
rspec_config.rb file :

c.fail_fast = true
c.color = true
end

"Hello, #{who}!"
end
UPDATE
Getting new error as :-
While I changed c.color = true to c.color_enabled = true

UPDATE
So, I updated rspec to v3.0.0 and changed Rakefile gem 'rspec', '~>3.0.0' and c.color = true back. Everything is working now(getting some deprecation warnings, but nothing critical), getting the output that is in the tutorial. Guess I just had to updae my rspec and change the version in the Rakefile. Thank you so much :)
Your error log is showing you are in rspec-core-2.0.0 version and your error is saying -
rspec_config.rb:3:in `block in <top (required)>': undefined method `color=' for
#<RSpec::Core::Configuration:0x0000000293dee0> (NoMethodError)
Now Deprecate config options confirms that below versions of 2.99.0.rc1 / 2014-05-18 or 2.99.0 methods were - #color_enabled, #color_enabled= and #color?. Which are changed since 2.99.0 to #color, #color= and #color_enabled?.
I got the information from the changelog as I linked -
Deprecate #color_enabled, #color_enabled= and #color? in favour of #color, #color= and #color_enabled? output. (Jon Rowe)
Thus you need to write as
RSpec.configure do |c|
c.fail_fast = true
c.color_enabled = true
end
Regarding your new error, I found it as a bug undefined methodrun_all' for []:Array`. Which has been fixed in this patch. Check this Rspec issue.
My suggestion use Rspec 3.0, at least you will be happy. In this case revert the color_enabled to color.
Hope this would help you.

The error is happening inside ActiveSupport::BufferedLogger#add method call and you appear to be monkey-patching this class. The internals of ActiveSupport::BufferedLogger have likely changing between the versions of Rails you're using.
Try removing all of the ActiveSupport::BufferedLogger code from your environment.rb to work past this error and get your app running. Then, if you still need the monkeypatch (don't know why), you'd have to rewrite it on top of the newer version of the class.
I have series of zip files under #workingdir, and am trying to unzip the files that match #Regexp, and print the lines from them.
require 'zip/zip'
#workingdir = '/my/dir/structure/*.zip'

Dir.glob(#workingdir) do |zips|
Zip::ZipFile.open(zips) do |file|
file.each do |search|
tempFile = file.read(search)
tempFile.each do |line|
if (line =~ #Regexp ) then

I tried tempFile.grep, and received the same error, except that grep was an undefined method. I believe I need to define a class.
Turns out my code had two problems. 1) My regular expression was being processed as a string (I should not have used the quotes). 2) Seeing as it runs fine otherwise on Ruby 1.8.7, I suspect the is a difference in how 1.8.7 and 1.9.1 process the 'each' method. If anyone has additional insights, I'm more than happy to hear them. The code below works fine on 1.8.7:
require 'zip/zip'
#workingdir = '/my/dir/structure/*.zip'
#Regexp = /regexp/i
Dir.glob(#workingdir) do |zips|
Zip::ZipFile.open(zips) do |file|
file.each do |search|
tempFile = file.read(search)
tempFile.each do |line|
if (line =~ #Regexp) then
puts zips + ': ' + line.chomp
end
end
end
end
end
Thanks again everyone!
I'm not sure it's REXML or ruby issue.
But this is happening when I work with REXML.
The program below should access elements of each xml file in the directory.
#!/usr/bin/ruby -w

Dir.chdir("/home/askar/xml_files1") {
p "Now we're in: " + Dir.pwd
if File.exist?(Dir.pwd)
xml_files = Dir.glob("ShipmentRequest*.xml")
Dir.foreach(Dir.pwd) do |file|
xmlfile = File.new(file)
xmldoc = Document.new(xmlfile)
end
else
puts "It's empty"
end
}

When I comment out:
#xmldoc = Document.new(xmlfile)
it's not giving errors.
Folder /home/askar/xml_files1 contains only 3 xml files.
I'm using Linux Mint Nadia and
ruby -v
ruby 1.9.3p429 (2013-05-15 revision 40747) [x86_64-linux]
If you noticed, for some reason, error shows ruby 1.9.1. Is this an issue?
I think #halfelf is correct here. The API docs say that Dir.foreach will iterate over every entry in the directory - and in Unix, that includes the two directories . and ...
A couple lines before your Dir.foreach call, you use glob to build an array of files called xml_files. What happens if you iterate over that in your loop instead?
Just a guess: Not everything returned by Dir.foreach(Dir.pwd) is a file that can be read. Some of them are directories.
Using Nokogiri, here's how I'd write this:
#!/usr/bin/ruby -w
require 'nokogiri'
DIRNAME = "/home/askar/xml_files1"
puts "Current directory is: #{ Dir.pwd }"
Dir.chdir(DIRNAME) do
puts "Now in: #{ DIRNAME }"
xml_files = Dir.glob("ShipmentRequest*.xml")
if xml_files.empty?
puts "#{ DIRNAME } is empty."
else
xml_files.each do |file|
doc = Nokogiri::XML(open(file))
# ... do something with the doc ...
end
end
end
