"NoMethodError: undefined method` specificity 'for [: not (.block-layered-nav)]: Array"

Question

This is in addition to this post: Unable to compile SCS SCSI in Magento CE 1.9

Windows 8.1 / PowerShell Compass 1.0.1 (Polaris) Sass 3.4.6 (Selective Steve) ruby 2.1.3p242 (2014-09-19 revision 47630) [x64-mingw32] 

I deleted "from: not (". Button ")> a: not (.button)

New error:

 "NoMethodError: undefined method `specificity' for [:not(.block-layered-nav)]:Array"; 

Commented on the block, after which we get:

 "NoMethodError: undefined method `specificity' for [:not(:last-child)]:Array" 

Answer 1

This looks like a known issue with Sass 3.4.6 . You will need to downgrade to 3.4.5 until it is fixed.
