Hi Anil,

You're missing the node-less library. The fixes:

sudo apt-get install node-clean-css 
sudo apt-get install node-less

This will install both the node-less JS library and the CSS rendering which Odoo 9 needs.

Hi All,

I have fixed my clean-css issue.

clean-css was not interpreated thats why all the .less file was not loaded properly.

After execution of this command now its works well.

npm install -g less-plugin-clean-css

I have setup that plugin as global and now its works perfect in my system.

This is not working for me. I installed Odoo9 with and then with this command LESS: sudo apt-get install node-clean-css sudo apt-get install node-less Then I do this: sudo npm install -g less-plugin-clean-css But it's not working, LESS error like: - /web_tip/static/src/less/tip.less - /web_calendar/static/src/less/web_calendar.less - /web_diagram/static/src/less/diagram_view.less - /web_kanban/static/src/less/kanban_dashboard.less - /web_kanban/static/src/less/kanban_view.less - /web_settings_dashboard/static/src/less/dashboard.less


Answer by Gajanan Kathar was useful but need to set npm registry before update, i.e. execute following command just before bullet point 4.

npm config set registry http://registry.npmjs.org/

Sure you have to install some package like this: 

sudo apt-get install node-clean-css

sudo apt-get install node-less

But, according to this comment in a bug report, you have to install website_blog module too: https://github.com/odoo/odoo/issues/8676#issuecomment-142604714

It works for me.

This error shows because of two reasons

  1. You don't install required packages and plug-ins on your ubuntu system or

  2. Install packages and plug-ins are outdated

To overcome this problem try this commands on your ubuntu terminal

  • sudo apt-get install curl

  • curl -sL https://deb.nodesource.com/setup_0.10 | sudo bash -

  • sudo apt-get install -y nodejs

  • sudo npm install -g npm (to update npm)

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