Drupal 8.x

After an upgrade from D7 to D8 pathauto ist not working. 

The status report says "The URL alias field must be installed.". Is this the problem? How can I solve this?

Hello Guys
I need to set Email-Field in registration page "Not Required".
In fact I want users would be able to register with only username_field and password_field.

Thanks

Hello,

I have a requirement and I just cant figure it out how. 

It is a real estate website. I need to add list of properties. I have a content type which has title, body, address, img, etc. 

I added 5 houses for the content type. 

Example:

House 1 - County 1, state 1

House 2 - county 1. state 1.

House 3 - county 3, state 1

House 4 - county 1, state 2

House 5 - county 1, state 2

I like to create a google map block which will show a numeric number of houses by the counties. 

Map should show:

I'm am trying to write a module that will assign a role to a user on once they have purchased a product (Drupal 8.8.2, commerce 8.x-2.16). I have googled and there are bits and pieces (e.g. "write a new class called an event subscriber to assign that user role on the "placed" transition") that suggest how this could be done.

Hi,

i was trying to update drupal 8.1 to 8.2 using composer, but it fails with the following error

composer outdated "drupal/*"

#error ;

Fatal error: Allowed memory size of 1610612736 bytes exhausted (tried to allocate 4096 bytes) in phar:///usr/local/bin/composer/src/Composer/DependencyResolver/Solver.php on line 220

i tried updating the memory_limit to -1 in php.ini, but the results were same.Any other workarounds to do this 
i am using Mac.

I'm in the process of migrating a site from Drupal 8.7.x to 8.8.x (8.8.2 in this case). Up until this site, all my work has been in Drupal 7 or below, so I'm learning Drupal 8 and it's new structures, methods, etc. with this site.

Both my test site (8.8.2) and my production site (8.7.10) have a web folder inside the site root:

test.site.com/web/

prod.site.com/web/ (which is actually www.theurl.com)
