Issue generating SASS from CSS

[baphled]

This seems to be a relatively new issue, though I have not tried to
convert from CSS to SASS in a few months. When ever I try now get the
following error:

/Library/Ruby/Gems/1.8/gems/haml-2.2.15/lib/sass/css.rb:75:in
`initialize': can't convert nil into String (TypeError)

Does it happen for  you all the time or only with certain inputs?

If input dependent, please post that css using http://gist.github.com or http://pastie.org and send us the link.

It's a consistent issue, I've had a play around and it seems to happen with even the most basic of CSS files.

[Nathan Weizenbaum]

What version of Ruby are you using? How are you calling css2sass?

[Ryan Michael]

I'm having a very similar problem, but it's coming from my compass
watcher script (using rails/compass). My sass files look like this:

// site.sass
@import partials/base.sass
@import partials/mixins.sass
@import partials/products.sass

body
+i18n_highlighting

#user_block
float: right
+inline_list

#nav_block
float: left
clear: both
+inline_list
margin-bottom: 20px

#content_block
clear: both

#footer_block
clear: both
text-align: center
+inline_list

// _products.sass
@import mixins.sass

#sidebar
float: left
width: 200px
margin-left: 20px

#browse_content
margin-left: 270px
+browse

// _mixins.sass
=inline_list
ul
display: inline
li
display: inline

=i18n_highlighting
.translation_missing
background: yellow

=browse
.browsing_block
width: 300px
float: left

compass tries to compile site.sass and gives the the following error:

TypeError: can't convert nil into String

Not sure what's causing this but it's a PITA. The oddest part is that
it doesn't seem to be consistent - sometimes it happens and sometimes
it doesn't (on the exact same code)

[Nathan Weizenbaum]

Ryan, I think your issue is different. Your problem seems to be that the :cache flag is set for Sass::Plugin.options, but the :cache_location option isn't. I've just pushed a fix to the stable branch that fixes this bug. For now, if you explicitly set "Sass::Plugin.options[:cache_location] = Sass::Engine::DEFAULT_OPTIONS[:cache_location]", this should work fine.

[Nathan Weizenbaum]

Actually, these options should automatically be merged with the default options. What happens when you do "p Sass::Plugin.options"?

[Chris Eppstein]

For compass the way you directly set sass options is different. You need to assign a hash to the sass_options property. 

http://wiki.github.com/chriseppstein/compass/configuration-reference

sass_options = {

:cache_location =>    Sass::Engine::DEFAULT_OPTIONS[:cache_location]

}

[Chris Eppstein]

There's not a good place for him to add that in a compass project. I suggest removing the sass cache directory. 

Hunt & pecked on my iPhone... Sorry if it's brief!

[Nathan Weizenbaum]

The directory isn't the problem. The problem is that somewhere Sass::Plugin.options[:cache_location] is getting set to nil. This is causing update_stylesheets to fail.

[Ryan Michael]

OK, well I'm confused.

What file does compass use for options in a Rails install? The wiki
gives the file syntax but I can't find any files that look right.

I'm also confused. Why are you using the compass watcher on a rails
project?

I'm using Spree, which has a sort of wonky extension system and I couldn't get the standard compass install to compile at page load so I just threw in a watcher script to save myself the time of trying to figure out how to make compass play well with the extensions.

Basically (if you're not familiar with Spree) I'm developing an extension that lives in RAILS_ROOT/vendor/extension/blah along with a couple other ones, and ideally compass would be watching the sass dir of each extension.  Looking at the config documentation you linked to it appears that the sass_dir must be a string.

I should probably move this discussion to the Spree list; they probably already solved this issue and I just haven't been able to find it.  

Thanks for all you help btw.

-Ryan

[Chris Eppstein]

Let me know if there's any additional support needed on my end.

[JoshL]

I also started getting this error after upgrading to pre 3

Any thoughts? How can I downgrade?

Downgrading:

sudo gem uninstall compass

And it will give you a list of installed versions to uninstall.
