Installing Drupal

I am trying to get a D8 with drupal commerce site ready top open it to the public.

It is currently open to testers.

The site is an upgrade from D7 with ubercart. I have tried to run upgrades after the one I now use but those upgrades did not import orders which I do need to have as a reference.

I have had an wsod before which I was able to solve by comparing the view settings of an empty install with mine and I had changed stuff I should not have changed.

However, for this error it dous not work.

Here is the error report:

I'm getting this error when I try to modify a content if you can help me

Hello,

I succesfull installed the Drupal codebase with "composer create-project drupal/recommended-project".

Then I have "Fatal error: Cannot use Composer\Plugin\Capability\CommandProvider as CommandProvider because the name is already in use in phar:///usr/local/bin/composer/src/Composer/Plugin/PluginManager.php(196) : eval()'d code on line 10" after the "./composer.json has been updated" when I try to install DrupalConsole and Drush with "composer require drupal/console drush/drush".

Any idea how I can fix it ?

Thanks.

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composer outdated "drupal/*"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)

As someone trying to move to Drupal 8 and learn composer it's frustrating that just when you think you have something new down, the whole process is uprooted and a long tutorial about how to update everything to use the newest composer method is now on my plate.
