Как установить расширение автосохранения Chrome?

Я бы хотел установить плагин chrome autosave на Ubuntu. когда я пытаюсь установить его с помощью этих шагов https://github.com/NV/chrome-devtools-autosave-server , я получаю некоторые ошибки ...

там не было установлено узел и npm из коробки на Ubuntu 12.10. Поэтому я установил npm и узел с этими командами.

sudo apt-get install npm
sudo apt-get install node

и я попытался установить автосохранение

, вот вывод:

sudo npm install -g autosave
npm http GET https://registry.npmjs.org/autosave
npm http 304 https://registry.npmjs.org/autosave
npm http GET https://registry.npmjs.org/commander
npm http 304 https://registry.npmjs.org/commander
/usr/local/bin/autosave -> /usr/local/lib/node_modules/autosave/bin/autosave

> autosave@1.0.2 install /usr/local/lib/node_modules/autosave
> node ./scripts/install.js

nodejs for Debian
=================

packaged modules
----------------

The global search path for modules is
/usr/lib/nodejs

Future packages of node modules will use that directory,
so it should be used wisely.


user modules
------------

Node looks for modules in ./node_modules directory first;
please read node#modules documentation carefully for more information.

Node does not look for modules in /usr/local/lib/node_modules,
where npm put them.
Please read npm-link(1) of npm package, to understand how to properly
use npm-installed modules in a project.

Note that require.paths is not supported in future node versions.
See also node(1) for more information about NODE_PATH.


nodejs command
--------------

The upstream name for the Node.js interpreter command is "node".
In Debian the interpreter command has been changed to "nodejs".

This was done to prevent a namespace collision: other commands use
the same name in their upstreams, such as ax25-node from the "node"
package.

Scripts calling Node.js as a shell command must be changed to instead
use the "nodejs" command.
