Can't install drupal 8 commerce checkout module

问题

I'm trying to install drupal 8 commerce checkout module, but I'm getting the error:

Unable to install Commerce Checkout due to unmet dependencies: core.entity_view_display.commerce_product_variation.default.summary (commerce_product.commerce_product_variation_type.default)

I can't find the problem, what it could be and how to fix it?

回答1:

It looks like we have a soft-dependency issue on Commerce Product. Please install Commerce Product first. This is an issue due to the default checkout summary.

回答2:

You can install commerce module with all components using composer:

cd /path/to/drupal8
composer require "drupal/commerce"

You also can install individual components with composer e.g

cd /path/to/drupal8
composer require "drupal/commerce_authnet"

Try to install this module in this way. :)

I fixed this issue by creating a product variation "Default" I had deleted the variation that was there by default when setting up commerce.
