Installing Locally on Bash on Windows

Is this the best install method for you?

In most cases, we recommend doing an internet-based installation on Heroku instead. If you decide to do a local installation, be sure to read our page on local installations to help you understand what’s going on, particularly this section: Should I use a local installation?

If you just want to quickly set up a copy of Tabbycat to run locally on Windows, we recommend installing using Docker, which is much easier than the process below.

Requisite technical background

Bash on Windows is in beta, so you should be confident with command-line interfaces, have at least some experience with Linux and, most importantly, be willing to work with beta systems. This means that Bash on Windows isn’t yet fully stable and some features are incomplete. We’ve managed to get it going, but we haven’t rigorously tested it, so if you’re going to use this for a real tournament, you should either run an entire test tournament first or use a different installation method (like Docker).

If you’re not already familiar with Bash on Windows, you should be willing to familiarise yourself with it, including potentially things not mentioned in these instructions. While a background in the specific tools (Python, etc.) we use will make things easier for you, it’s not necessary: we’ll talk you through the rest.

Advanced users

Tabbycat is a Django project, so can be installed in any manner that Django projects can normally be installed. For example, if you prefer some SQL system other than PostgreSQL, you can use it so long as it’s Django-compatible. Just be aware that we haven’t tried it.

Differences from the Linux installation

For the most part, these instructions mirror those for doing local installations on Linux. The only difference is that, rather than installing PostgreSQL on Linux, you’ll install PostgreSQL for Windows. The reason for this is that PostgreSQL doesn’t yet work on the Windows Subsystem for Linux. As of February 2017, there is a fix on the Windows Insider Preview Build, but it’s still making its way to general availability.

This has a number of consequences:

  1. You’ll still install the PostgreSQL client on the Linux subsystem, using that to communicate with the server on Windows.
  2. Because you won’t install the PostgreSQL server, you need to install libpq-dev instead, in order for the psycopg2 module to work.
  3. These instructions will direct you to create the PostgreSQL role and database in pgAdmin, just like in the Windows instructions.

Short version

First, install PostgreSQL for Windows (on Windows, not on the subsystem for Linux). Once you’ve set it up, create a new role and database as instructed in the Windows instructions in section 3. Set up a new database. Then, in a Bash on Windows shell:

curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -    # add Node.js source repository
sudo apt-get install python3-dev python3-venv libpq-dev postgresql-client-9.6 nodejs

# either
wget https://github.com/czlee/tabbycat/archive/v1.4.5.tar.gz
tar xf v1.4.5.tar.gz
cd tabbycat-1.4.5
# or
git clone https://github.com/czlee/tabbycat.git
git checkout v1.4.5                                         # or master

Then create local_settings.py as described in the Linux instructions, then:

python3 -m venv venv
source venv/bin/activate
pip install --upgrade pip
pip install -r requirements_common.txt
npm install
cd tabbycat
dj migrate
dj collectstatic
dj createsuperuser
waitress-serve wsgi:application

1. Install dependencies

Follow these instructions:

2. Get the source code

Follow section “2. Get the source code” in the Linux instructions, on the Bash subsystem.

3. Set up a new database

Follow section “3. Set up a new database” in the Windows instructions (in Windows).

4. Install Tabbycat

Follow section “4. Install Tabbycat” in the Linux instructions, on the Bash subsystem.

Starting up an existing Tabbycat instance

To start your Tabbycat instance up again next time you use your computer:

$ cd /mnt/c/path/to/my/tabbycat/directory
$ source venv/bin/activate
$ cd tabbycat
$ waitress-serve wsgi:application
