Install and Setup Bench

Bench is the command line tool to manage Frappe apps and sites.

Installation

If you haven't installed Bench, follow the Installation guide. After installation, you should be able to run commands that start with bench .

Run the following command to test your installation:

$ bench --version
5.1.0

Create the frappe-bench directory

Let's create our project folder which will contain our apps and sites. Run the following command:

$ bench init frappe-bench

This will create a directory named frappe-bench in your current working directory. It will do the following:

Create a python virtual environment under env directory.
Fetch and install the frappe app as a python package.
Install node modules of frappe .
Build static assets.

This will start several processes including a Python web server based on Gunicorn, redis servers for caching, job queuing and socketio pub-sub, background workers, node server for socketio and a node server for compiling JS/CSS files.

The web server will start listening on the port 8000 but we don't have any sites yet to serve. Our next step is to create our app and create a site that will have this app installed.

Make sure not to close the terminal where bench start is running. To run bench commands, create another terminal and cd into the frappe-bench directory.

Good job on following the tutorial so far!
