Problem

If you update ICU on macOS, some packages are dynamically linked against a specific version, but the older version might dissapear. You'll see this with something like,

$ stack --stack-yaml=stack-8.0.2.yaml install --extra-lib-dirs=/usr/local/opt/icu4c/lib --extra-include-dirs=/usr/local/opt/icu4c/include
...
HaRe-0.8.4.1: copy/register
brittany-0.11.0.0: copy/register
Progress 18/20

Toolchain

We have the choice of either using Nix or Stack. Stack is definitely the easiest by far, but Nix will technically be able to provide the most stable build result (assuming it works on macOS...).

To build the sample app with nix, we can do,

$ git clone https://github.com/dmjio/miso && cd miso/sample-app && nix-build

and with stack,

Jump straight into toying with PureScript!

Also, if you know JavaScript already, you might find this video interesting, which demonstrates the neat ability to look directly at the very readable generated JavaScript.

Toolchain

We need various tools to get started developing PureScript in a modern fashion. Let's first tackle the npm installable ones,

$ npm install -g psvm psc-package pulp
