I have installed MailChimp extension from reference link but getting errors below :-


Warning!file_get_contents(/var/www/html/austinsdiving/app/code/Ebizmarts/MailChimp/etc/module.xml): failed to open stream: Permission denied



Compile Time:-

[ReflectionException] Class Mailchimp does not exist


Please help me

  • It is simply the folder's permission problem. Please check and fix the folders permission and try again. May 9, 2018 at 11:24
  • This happens because their extension sucks. Even their installation guide is not clear, they start by guiding you to download the extension via the market place, and then proceed to install it via the admin panel. Other extensions I found can always be installed by one of the following: composer, admin->marketplace, download and upload manually into app/data. Mar 23, 2021 at 7:11

You need to also require mailchimp lib, you can install by below command.

composer require ebizmarts/mailchimp-lib

Note that it may require other core library. I think first you need to install ebizmarts/mailchimp-lib package using composer.

composer require ebizmarts/mailchimp-lib

I have fixed same issue with composer command.

composer require ebizmarts/mailchimp-lib

You can also download zip folder of library.
