odoo9运行中提示无法运行 /usr/bin/lessc 问题。
进入服务器发现bin目录下没有lessc。需要安装。
参考odoo 8.0安装尝试解决如下：

Less CSS via nodejs
on Linux, use your distribution’s package manager to install nodejs and npm.
Warning
In debian wheezy and Ubuntu 13.10 and before you need to install nodejs manually:
$ wget -qO- https://deb.nodesource.com/setup | bash –
$ apt-get install -y nodejs
In later debian (>jessie) and ubuntu (>14.04) you may need to add a symlink as npm packages call node but debian calls the binary nodejs
$ apt-get install -y npm
$ sudo ln -s /usr/bin/nodejs /usr/bin/node
Once npm is installed, use it to install less and less-plugin-clean-css:
$ sudo npm install -g less less-plugin-clean-css
on OS X, install nodejs via your preferred package manager (homebrew, macports) then install less and less-plugin-clean-css:
$ sudo npm install -g less less-plugin-clean-css
on Windows, install nodejs, reboot (to update the PATH) and install less and less-plugin-clean-css:
C:\> npm install -g less less-plugin-clean-css
——–cetos6.5——-
yum install -y nodejs
yum install -y npm
ln -s /usr/bin/nodejs /usr/bin/node
npm install -g less less-plugin-clean-css
reboot
