Reinstall the Magento software

A contributing developer reinstalls Magento by updating composer.json to specify the Magento product version and component versions desired and runs composer update.

To reinstall the Magento software as a contributing developer:

  1. Log in to your Magento server as a user with permissions to modify files in the Magento file system (for example, the switch to the Magento file system owner.
  2. Make a backup copy of composer.json in your Magento installation directory:

    1
    
    cd <magento_root>
    
    1
    
    cp composer.json composer.json.bak
    
  3. Open composer.json in a text editor.
  4. Locate the following line:

    1
    2
    3
    
    "require": {
          "magento/product-community-edition": "<version>"
    },
    
  5. Replace <version> with the version to which you want to upgrade, where <version> is the product version to use.

    (The product version is in the format 2.0.x)

.

  1. Save your changes to composer.json and exit the text editor.
  2. Enter the following command:

    1
    
    composer update
    

    Wait for dependencies to update.

  3. Install the Magento software.
