Emmet is not installed properly. Try this...with Sublime Text 3083, latest emmet and Pyv8 binaries and Python 3.3.0 (it should work with latest Python also)
- Install Python and Sublime if you haven't done that yet! ;)
- Download emmet-sublime-master.zip at github. Forget Package-Control! In fact if you have emmet installed via Package Control just remove it.
- Go to: c:\Users-your user-\AppData\Roaming\Sublime Text 3\Packages\
- Create a 'Emmet' folder, respect the caps.
- Decompress the emmet-sublime-master.zip inside the Emmet folder.
- Download your pyv8 binary at github.
- Create a 'PyV8' folder (outside Emmet folder, c:\Users-your user-\AppData\Roaming\Sublime Text 3\Packages).
- Inside PyV8 create a folder with the exact same name of the pyv8 binary you just downloaded (example: pyv8-win64-p3)
- Decompress the binary there.
- Restart Sublime Text 3.
It should work!
