Installing Python 3.7.4 on Raspbian =================================
As of July 2018, Raspbian does not yet include the latest Python release, Python 3.7.4. This means we will have to build it ourselves, and here is how to do it.
Install the required build-tools (some might already be installed on your system).
<?php | |
namespace App\Providers; | |
use Illuminate\Support\Collection; | |
use Illuminate\Pagination\LengthAwarePaginator; | |
class AppServiceProvider extends ServiceProvider | |
{ | |
public function boot() |
<?php // Do not include this if already open! | |
/** | |
* Code goes in theme functions.php. | |
*/ | |
add_filter( 'woocommerce_defer_transactional_emails', '__return_false' ); |
#!/bin/bash | |
sudo add-apt-repository -y ppa:git-core/ppa | |
sudo apt-get update | |
sudo apt-get install git -y |
