Error with Compass polling on windows 7 - ruby

I am attempting to work locally on a PHP application which I cloned from the Git repository my partner and I use.
He uses a Mac, and until now I have been working on the app in a virtual Ubuntu Linux environment. Both environments have been able to use Compass polling with the same file structure and files.
On Windows 7, I run Compass commands from Cygwin, and this is the command I use to have Compass poll from the root directory of the app (C:/wamp/www/application):
compass watch --trace src/Application/ApplicationBundle/Resources/compass/
When I then make a change to a .scss file, I receive the following error:
ArgumentError on line 716 of /usr/lib/ruby/1.8/pathname.rb: different prefix: "/
/cygdrivecwampwwwlimelightsrclimelightlimelightbundleresourcescompasssrcpartials

All I've been able to find through searching is that it may have something to do with the fact that Windows capitalizes its drive names, although the lack of slashes in the returned path makes me think the problem may be elsewhere.
Does anyone know why I might receive this error in Windows, but not other platforms?
NOTE: I have found a work-around involving installing ruby (and compass) through Windows' command prompt rather than Cygwin, and that should work fine for now. Still, if anyone has ideas, I'm still curious as to what the problem could be.

According to this commit, this is a problem caused by a compass dependency called FSSM. It is used to monitor file changes in compass. A workaround is described in this comment.
It seems that FSSM detects that ruby is running inside a Windows box, and treats paths in the Windows' way (C:\blabla). Commenting out the line 26 of the file <fssm_gem_path>/lib/fssm/pathname.rb makes compass watch work as expected. You can also add
unless path[0, 1] == File::SEPARATOR
to the end of line 26 to make it work.

I thought I'd just provide a little more info to help people find the pathname.rb file.
On the cygwin prompt type:
gem env
This (unsurprisingly) brings up a load of info about your Ruby Gems installtion. Look for the line which specifies the INSTALLATION DIRECTORY. Mine was:
/usr/lib/ruby/gems/1.8
Now in Windows Explorer navigate to this location but substitute "usr" for your cygwin installation directory. Therefore the above path becomes:
C:\cygwin\lib\ruby\gems\1.8
Once in this location drill down until you come across the fssm gem directory.
Within this [fssm] directory go into:
/lib/fssm/
...and there you should find the pathname.rb file.
Edit it as above and all is well. I hope this helps.

See here for a possible fix:
http://rails.webintellix.com/2010/05/27/error-in-ruby-relative_path_from-call-on-windows/

I was running into this same error with a slightly different setup. My project folder was on a network drive (ruby and sass/compass installed locally), and every time I made a change to a .scss file compass watch would crash with similar errors to the OP. I solved the issue by mapping my network drive instead of accessing it directly via the network (right clicked on My Computer and choose map network drive so I could access my remote drive at A:).
Now, instead of doing 'compass watch //SERVERNAME/My_Project' (I'm using Git Bash), I do 'compass watch a/My_Project' and compass stopped crashing.
Hope that helps someone else.

Using Cygwin, re install a compass dev release (such as 0.13+). Works for me with Compass 0.13.alpha.4 (Markab)
To do so:
gem uninstall compass
gem install compass --pre --no-rdoc --no-ri

Has anyone managed to add custom icons into Ionic in Windows?

I refer the instructions here
What I did (on Windows):
Install fontforge through web instead of 'brew'
Install SASS through Ruby GEM
Place my-icon.svg inside src/ (of the ionicons-master)
Run the python ./builder/generate.py
I think I am very closed. Until i saw this error message:
windowsError: The system cannot find the file specified
And I think I get even closer when I saw the last post of this link
But, I don't get what it means. I downloaded the .exe but it doesn't work.
Is it the python build only meant for MAC? Has anyone managed to make this work in Windows?

Installing the correct environment for Angular with Compass and all other Node dependencies

I am just trying to make a local development environment that isn't on my work computer, and I keep getting an error:
Warning: Errno::ENOENT on line 441 of /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/pathname.rb: No such file or directory - /Users/johnpett/Desktop/Node/app/bower_components
Run with --trace to see the full backtrace Use --force to continue.
I have installed all the Ruby parts and Yeoman to build the app scaffold, but I can't seem to run the 'grunt server' command without throwing up this error.
The error is quite clear, a grunt-plugin require that file...
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/pathname.rb
Anyway ruby components are needed usually if you plan to use compass, if not, you can comment the "compass" sub-task in the "server" task in Gruntfile.js
Your folder was surely not called bower_components at that time. I guess you used yeoman.
In your compass task config you should have modified bower_components.

heroku toolbelt not running on Windows XP

I downloaded the latest toolbelt for Windows; however, when I try to launch any heroku command from DOS I get:
c:/Program Files/Heroku/lib/heroku/updater.rb:126:in fork': fork() function is unimplemented on this machine (NotImplementedError)
from c:/Program Files/Heroku/lib/heroku/updater.rb:126:inbackground_update!'
from c:/Program Files/Heroku/lib/heroku/updater.rb:111:in inject_libpath'
from c:/Program Files/Heroku/bin/heroku:19:in'
My purpose is to deploy a Play! app on heroku. I'm using Windows XP SP3. Anybody to enlighten me because I'm having headache.
I just ran into the same problem. My solution was to comment out the call to fork.
Navigate to your Heroku installation directory, and find the file updater.rb in the subdirectory lib\heroku.
Comment out lines 126 (should be pid = fork do), 143 (end) and 144 (Process.detach.pid).
That should do the trick.
In your home directory (i.e. C:/Users/xxx/.heroku/autoupdate.last) create a file called "autoupdate.last".
See updater.rb:
File.join(Heroku::Helpers.home_directory, ".heroku", "autoupdate.last")
I have a co-worker on Windows 7 who had this problem. He accidentally installed ruby 1.8.7. This error seems to occur when you are using ruby 1.8.7 with a current version of the Heroku Toolbelt (2.32.9 at this writing). Heroku Toolbelt seems to prefer Ruby 1.9.x. You can run gem install heroku, and the error goes away, but you will get warnings about the heroku gem being deprecated which means it will probably be missing current features. Update to ruby 1.9.x if you can. While valid in some cases, editing ruby files should be a last resort in my opinion.
I'm not sure which of these fixed issue, but one or both of them did:
1. Deselected "hidden" Users/[user]/.heroku" folder.
2. Deselected "read" only for folder.

Image paths in Compass CSS on Windows

I've been using SASS and Compass successfully on my Windows 7 x64 machine. Everything was working fine until I tried using the replace-text-with-images mixin.
I placed the image I'm trying to use in the correct place (t:\Website\stylesheets\stylesheets\images for my system), and checked that relative assets are enabled in my Compass config file. Still, when I try to compile, I get this:
t:\Website\stylesheets>compass watch -c config_with_refresh.rb
>>> Change detected to: code-n-apps.scss
WARNING: 'i_user.gif' was not found (or cannot be read) in t:/Website/stylesheets/images
Errno::ENOENT on line ["34"] of C: No such file or directory - t:/Website/stylesheets/images/i_user.gif
Run with --trace to see the full backtrace
>>> Compass is polling for changes. Press Ctrl-C to Stop.
The file is most definitely in that path, and is readable.
Any help would be most appreciated. Ideally, I'd like Compass to grab the images directly off my production server (http), but even having it work locally would be a major improvement.
You say that this is your image-path:
t:\Website\stylesheets\stylesheets\images
Then of course it will not find i_user.gif in
t:/Website/stylesheets/images/
Please double check your path, note that the first time you are using stylesheets/stylesheets and you want to load the image from stylesheets

Ruby cannot find sqlite3 driver on windows

I am trying to set up Ruby on Rails on windows. I am using the Flash Rails distribution that looks pretty good, but there is an issue with sqlite3. I found the threads telling me to install version 1.2.3, which installed fine. I'm using ruby 1.9.0, and every time I try and run a script (e.g. rake db:create) that uses the database I get an error message "no driver for sqlite3 found".
This apparently is a missing sqlite3.dll, but I have the dll in my %PATH%, and I have also tried copying it into the directory where I am running the script from, the directory where the sqlite3 ruby code lives.
Does anyone have any ideas? If possible I want all teh ruby stuff to be self contained so I can use it from a pen drive.
EDIT: To clarify, I already used gem install to install the ruby-sqlite3 gem - it is just non functional as it cannot find the sqlite3.dll (even though it is actually present in a directory on my %PATH%)
EDIT PART 2: After doing some more digging, the problem appears that ruby will not load the sqlite3_api.dll. I have copied it all over my filesystem, I just get a failure to read file. Other dll libraries in the same directory (e.g. zlib.dll) work fine!
I tried installing the dlls into system32, and that did not work either.
The problem put simply is that sqlite3-ruby 1.2.3 is not compatible with ruby 1.9. This is caused because ruby 1.9 does not use .dll files for c libraries it uses .so files instead. Additionally, since sqlite3_api.dll is written against msvcrt-ruby18.dll. This means that it specifically only will support ruby 1.8.*.
The good news is that there is a fat binary version that will support both ruby 1.8 and ruby 1.9. Uninstalling all former versions of sqlite3-ruby and then installing this one. (You may have to manually delete some versions the gem after uninstalling.) in order to install it use
install sqlite3-ruby --source http://gems.rubyinstaller.org
for more information see this website
Try installing the sqlite3-ruby gem:
gem install sqlite3-ruby
Something similar happened to me recently so I thought I'd update my answer.
For reference there's a sqlite3_api.dll file located in the gem's lib directory. Also the sqlite3.dll file needs to be reachable on the path. They are different files, the first is required by the gem to interface Ruby to C code, while the second contains the actual Sqlite implementation.
It's best to get the second file from the sqlite website and extract it to the Ruby\bin directory (as you shouldn't manually put DLL's into the windows or windows\system directories any more).
So for reference "sqlite3_api.dll" needs to be in:
Ruby\lib\ruby\gems\1.8\gems\sqlite3-ruby-1.2.3-x86-mswin32\lib
and "sqlite3.dll" needs to be on the path, possibly in:
Ruby\bin
As for the "driver not found" problem I would suggest trying the easy things first and making sure gems is installed correctly, up to date, and that the RUBYLIB and PATH environment variables are set appropriately. (System restart may be required to propagate the changes fully.)
Re this link
Download sqlitedll-3_6_10.zip and extract into ruby/bin!
Try going to sqlite.org download page and get the zipped up dll. Then put that in your c:\windows\system32 folder, that should allow Ruby to find it.
Restart your machine after running install sqlite3-ruby
To clarify, which gem are you using? sqlite-ruby or sqlite3-ruby?
They're part of the same project, but different releases. The key is that sqlite3 appears to have driver code included.
I assume you're attempting to use the first, since it's giving me the same error. If so, try switching.
Also.. How literal do you mean by this?
but I have the dll in my %PATH%
PATH=...;C:\sqlite\sqlite3.dll
PATH=...;C:\sqlite
The first will attempt to find C:\sqlite\sqlite3.dll\sqlite3.dll, AFAIK.
I use Ruby 1.8.7 (works with 1.9.1 too)
OS is WindowsXP SP3
Go to
http://www.sqlite.org/download.html
and Download file
sqlitedll-3_7_0_1.zip (265.19 KiB)
and unzip then we will get
sqlite3.dll
Copy sqlite3.dll to your bin folder
as C:\Ruby191\bin or C:\Ruby187\bin
then it works
