If you’ve encountered this issue, don’t panic. This article will guide you through the process of fixing the Magento 2 upgrade command eror and getting your store back online.

When this error occurs, it usually indicates a problem with the cache, file permissions, or dependency injection configurations. Fortunately, resolving this problem is relatively simple, and you can do it by following a few key steps.

What Causes Magento 2 Upgrade Command Error?

The Magento 2 upgrade command error typically appears when something goes wrong during the system upgrade process. Common causes of this issue include:

1. Corrupted Dependency Injection Configuration: The upgrade process may result in incomplete or corrupted DI configurations, leading to errors.
2. Permission Issues: Incorrect file or directory permissions can block Magento from executing the necessary commands after the upgrade.
3. Cache Inconsistencies: Magento stores cached data that could interfere with the upgrade process.

Fortunately, these issues can be easily fixed using simple commands.

Step-by-Step Guide to Fix the Magento 2 Upgrade Command Error

Follow these steps to resolve the Magento 2 upgrade command error:

Step 1: Delete the “di” Folder in the var Directory

The first step is to delete the “di” folder found in the var directory. The DI folder can sometimes cause problems with dependency injections after an upgrade.

• How to do it:
  • Log into your server via FTP or cPanel.
  • Navigate to the var directory in your Magento root folder.
  • Delete the entire di folder.

Step 2: Log into Your Terminal via SSH

Once you’ve deleted the folder, it’s time to access the terminal via SSH. SSH allows you to directly interact with your server and run the necessary Magento commands to fix the error.

• How to do it:
  • Use your SSH credentials to log into the terminal.
  • Navigate to your Magento root directory.

Step 3: Navigate to the “bin” Directory

Magento relies on its bin directory to manage commands. You’ll need to run some important commands from this directory to fix the upgrade command error.

• How to do it:
  • Run the following command to change the directory:
    bash

    cd bin

Step 4: Run the Dependency Injection Compilation Command

After navigating to the bin directory, it’s time to compile your Magento setup again. This will rebuild all necessary files and resolve any dependency injection errors caused by the upgrade process.

• How to do it:
  • Run the following command to compile your Magento 2 setup:
    bash

    sudo ./magento setup:di:compile

This command will ensure that all dependencies are correctly compiled.

Step 5: Return to the Magento Root Directory

Once the compilation is complete, navigate back to the root directory of your Magento installation to proceed with the next steps.

• How to do it:
  • Run this command to return to the root directory:
    bash

    cd..

Step 6: Set File and Directory Permissions

Incorrect file and directory permissions are a common cause of errors after Magento 2 upgrades. It’s crucial to ensure that Magento has the necessary permissions to execute its processes.

• How to do it:
  • Run the following commands to set proper permissions for files and directories:
    bash

    sudo chmod -R 755 . sudo chmod -R 777 var pub generated

These commands ensure that the necessary files are accessible by Magento.

Step 7: Clear Magento Cache

Finally, you’ll want to clear the Magento cache. This step ensures that any old or corrupt cache data is removed, allowing Magento to function properly after the upgrade.

• How to do it:
  • Run this command to clear the Magento cache:
    bash

    php bin/magento cache:clean

Once the cache is cleared, your website should be back online, and the Magento 2 upgrade command error should be resolved.

Conclusion: Resolve Magento 2 Upgrade Command Error Quickly

The Magento 2 upgrade command can cause frustration, but as we’ve outlined in this step-by-step guide, it’s easy to fix. By deleting the di folder, compiling dependencies, setting proper permissions, and clearing the cache, you can quickly get your Magento store back up and running.
