新手无本地Drupal站点，FTP环境下如何安装Imgix模块及Composer Manager？

Hey there! I’ve dealt with this exact scenario before—working on a Drupal site with only FTP access and no local environment to run Composer commands. Let me break down the step-by-step process to get Imgix up and running with Composer Manager, using your existing themes/xyz/vendor folder.

Step 1: Install & Enable Composer Manager First #

Since Imgix depends on Composer Manager, we need to get that set up first:

• Grab the latest stable version of Composer Manager (matching your Drupal core version) from its official Drupal project page.
• Upload the zip file to your site’s modules directory via FTP—this is usually sites/all/modules or modules/contrib depending on your site structure.
• Unzip the file, making sure the folder is named composer_manager (no extra version numbers in the folder name!).
• Log into your Drupal admin dashboard, go to the Modules page, find Composer Manager in the list, and enable it.

Step 2: Point Composer Manager to Your Existing Vendor Folder #

By default, Composer Manager looks for a vendor folder in your site’s root directory, but yours is in themes/xyz/vendor. We need to update the configuration to tell it where to look:

• Download your sites/default/settings.php file via FTP to your local computer.
• Add this line somewhere in the file (I usually put it near other configuration overrides):

  $config['composer_manager.settings']['vendor_dir'] = 'themes/xyz/vendor';
  

• Save the file and upload it back to your FTP server.

Step 3: Install Imgix Module & Its PHP Dependencies #

Now let’s get Imgix set up, along with its required PHP library (imgix/imgix-php):

1. Install the Imgix module:

   • Download the latest stable Imgix module zip (matching your Drupal version).
   • Upload it to your modules directory, unzip it, and make sure the folder is named imgix.
   • Go back to your Drupal admin Modules page and enable the Imgix module.

2. Add the Imgix PHP dependency:
   Since you can’t run Composer commands directly on FTP, you have two options to get the required library into your vendor folder:

   • Option 1: Local Composer Setup (Recommended)
     • On your local computer, create a temporary folder. Inside it, make a composer.json file with this content:

       {
         "require": {
           "imgix/imgix-php": "^2.0"
         }
       }
       

     • If you have Composer installed locally, run composer install in this folder. This will generate a vendor folder with the Imgix library and autoload files.
     • Upload the imgix folder from your local vendor directory to themes/xyz/vendor/imgix on your FTP server. Also, if your existing vendor folder doesn’t have an autoload.php file, upload that too.
   • Option 2: Manual Download
     • Go to the Packagist page for imgix/imgix-php and download the latest stable version zip.
     • Unzip it, then upload the imgix folder inside to themes/xyz/vendor/imgix on your FTP server.
     • Note: If your vendor folder doesn’t have an autoloader, you might need to add a line to your theme’s template.php or use Composer Manager’s autoload to load the library.

Step 4: Verify the Installation #

• Log into your Drupal admin, navigate to the Imgix configuration page (usually under Configuration > Media > Imgix).
• Enter your Imgix API key and source domain, then test by uploading a sample image to see if it’s served via Imgix.

Have others used Composer Manager to install Imgix? #

Absolutely! Lots of Drupal users have gone through this process, especially when stuck with FTP-only access. The biggest hurdles are pointing Composer Manager to the correct vendor directory and getting the PHP dependency uploaded properly—once those are sorted, it works smoothly.
