Welcome to the wonderful world of static typing! This guide will get you from zero to a simple project that is type checked with Pyre.
On Ubuntu, Mint, or Debian; use
apt-get and homebrew:
We tested Pyre on Ubuntu 18.04.5 LTS, CentOS 7, as well as OSX 10.11 and later.
We start by creating an empty project directory and setting up a virtual environment:
Next, we teach Pyre about our new project:
This command will set up a configuration for Pyre (
.pyre_configuration) as well as watchman (
.watchmanconfig) in your project's directory. Accept the defaults for now – you can change them later if necessary.
We are now ready to run Pyre:
This first invocation will start a daemon listening for filesystem changes – type checking your project incrementally as you make edits to the code. You will notice that subsequent invocations of
pyre will be faster than the first one.
