Answer 1

sudo apt-get install node-less 

After installation, just restart the openerp server and refresh your browser.

Answer 2

This error occurs almost every time a new installation of Odoo. (Especially with Ubuntu 12.04)

• First run these three commands in your terminal.

 sudo apt-get install python-software-properties sudo apt-add-repository ppa:chris-lea/node.js sudo apt-get update 

2. Then you install nodejs:

 sudo apt-get install nodejs 

3. Then you can check the nodejs version using:

 node -v 

4. It must be at least greater than> 0.10

 npm -v 

Must return a version of at least> 1.4

5. Then finally run the following command: whick will upgrade npm to a newer version and also install a smaller plugin:

 sudo npm install -g npm sudo npm install -g less less-plugin-clean-css
