As part of a new contract, I need to use the GOV.UK prototype kit - which is designed to enable people to quickly build out model applications and websites. I say “quickly”, but you still still need to do a fair bit of hand-crafting…
However, the kit only works with node version 4.2.2 or 4.2.3, whilst node’s most recent version is 5.2.0. If you come across issues during the prototype kit installation, then check your node version (node -v) first - as I found the installation fails completely without the right version.
The best way to deal with this, without downgrading your node installation, is to use Node Version Manager - aka nvm
This allows you to have multiple versions of node on your machine at once, and switch between them when working with different applications.
In your Terminal, type:
curl https://raw.github.com/creationix/nvm/master/install.sh | sh
This downloads the nvm package, and runs a set of commands to get nvm set up.
Now restart your Terminal.
This runs a few more commands. Without it, your system won’t know where to find nvm.
Note that you can get this to run automatically when your Terminal starts up by adding it into your bash profile. (.bash_profile on MacOSX)
To install node v 4.2.3 just type:
nvm install 4.2.3
Then, after it’s installed:
nvm use 4.2.3
To see which versions of node you have installed, type:
At this point, you can now follow the instructions to download and install the GOV.UK prototype kit
Once you’re done, then use the documentation at GOV.UK elements to understand how to use the CSS.
