If you are getting this error while building your visual studio solution. Make sure that you have installed LESS globally. If you have done so and you are still getting the issue or you can not install it globally follow below steps to fix it .
- Open your Node.js command prompt window. and run the command "where lessc"
- Make a note of your less npm folder. In my case it is "C:\Users\server_admin\AppData\Roaming\npm\"
- Open "Control Panel" -> "System" -> "Advanced System Settings". Under "Advanced" tab click on "Environment Variables". if you are using windows server you can directly search for Advanced System Settings and click on Environment variables section.
