Installing Drupal

I wish to install a local Drush (as a Composer dependency) with Drupal in a single action.

I understand that the first command is the way achieve what I seek:

• composer create-project drupal/drupal-project DIR_NAME
• composer create-project drupal/recommended-project DIR_NAME

Why are there two commands, one with a local Drush (as a Composer dependency) and another command without Drush at all? That's to ask, isn't Drush a standard and should be installed by default?

Hi everyone !

Hope you're well !

I decided to install my own Drupal 9 on local env. Windows 10. I have installed Xampp, make a copy of my website and paste it in the correct folder (it works well on my linux Mint distrib), create a virtual host for it, imported the last dump of the DB I have and finally configured the DNS.

All seem to be good excepted for the first loading of the home page:

Dear friends, 

I have a problem with the second step of installation. 

I send via composer all the files to the remote server and everything seemed okay, but when I tried display website installation, there nothing appears.

directory :tel_dir

website: https://telegraf.uk

The domain is correctly assigned to the directory.

So, according to guidance, I should use the command: https://telegraf.uk/tel_dir/web/core/install.php - but it does not work. 

Hello I'm new to Drupal, using Drupal 9 and composer version 2.3.10. When I try to install a theme by entering

composer require 'drupal/at_theme:^1.4'

into the command prompt I get this error:

In VersionParser.php line 521:

  Could not parse version constraint 1.4': Invalid version string "1.4'"

trying to update my local test servers from 9.3.15 to 9.4.2 before I update production servers. major headache!

I am on macOS , so I installed php 8.1 since php 7.3 is not compatible with D9.4. then php required apache updated because built-in apache would not work. got it configured.  and update is having serious issues.

I decided to try a new install of 9.4.2. this is the error after clicking save and cont on lang and save and cont on choose profile standard, verify req shows below with no button to continue. how to I fix these errors?

I have installed Drupal 9 on two websites with two different themes.  One website is going to be an ecommerce site and the other one is more of a general blogging site.  After installing Drupal and loading the theme that is specified for the purpose of the website, the home page suggests to read the User's Guide.  But it is the general User's Guide of drupal.  I suppose that is OK but I need to know specifically what section of the User's Guide I need to focus on.
