Post & DHL Shipping in Magento®

Problem

The DHL Shipping module for Magento 2 cannot be enabled with the following command:

php bin/magento module:enable Dhl_Shipping

This error message occurs:

Unable to change status of modules because of the following constraints:

Cannot enable Dhl_Shipping because it depends on disabled modules:

Dhl_LabelStatus: Dhl_Shipping->Dhl_LabelStatus

When trying to enable the Module Dhl_LabelStatus first, a very similar error shows up:

Unable to change status of modules because of the following constraints:

Cannot enable Dhl_LabelStatus because it depends on disabled modules:

Dhl_Shipping: Dhl_LabelStatus->Dhl_Shipping

Cause

There is a circular dependency between the modules DHL Shipping and DHL Label Status.

Solution

Both modules must be enabled at the same time using a single command:

php bin/magento module:enable Dhl_Shipping Dhl_LabelStatus
