Steps for installation of canvas on Ubuntu 10.04
sudo apt-get install libcairo2-dev
Download jpeg library. At the time of writing it was available here
Unpack the downloaded file. Will be in a folder jpeg-8c.
sudo make install
Once this is done install canvas
npm install canvas
That’s it. Check out a few examples and you’re done.
npm will install packages locally, in ./node_modules. So if you are in /home/foo:
user@host:/home/foo$ npm install Haraka
Haraka will be installed in /home/foo/node_modules/Haraka. If you want to install a module globally (by default in /usr/local/lib/node_modules), supply the -g switch:
user@host:/home/foo$ sudo npm install -g Haraka
Haraka will be installed in /usr/local/lib/node_modules/Haraka, and the command haraka will be symlinked to /usr/local/bin/haraka.
It’s recommended that any dependencies be installed locally. This way, you never have to bother with different packages requiring different versions of their dependencies, aka “dependency hell”. I have all my projects in ~/development/projects, and each node project has it’s own node_modules folder.
Steps for uninstalling one version of node and installing another:
