I just downloaded Sensei LMS Master 2.0.1 + Sensei Drip 2.0.0 and had the same issue but I found the origin of it. It said the Drip plugin needed Sensei 1.11.0 minimum and it was there, but it couldn’t find it.
In ../sensei-content-drip-master/includes/class-scd-ext-dependency-checker.php, line 73, replace:
$search_sensei = array(
‘sensei/sensei.php’, // Sensei 2.x from WordPress.org.
‘sensei/woothemes-sensei.php’, // Sensei 1.x or Sensei 2.x Compatibility Plugin.
‘woothemes-sensei/woothemes-sensei.php’, // Sensei 1.x or Sensei 2.x Compatibility Plugin.
);
with:
$search_sensei = array(
‘sensei-master/sensei-lms.php’, // Sensei 2.x from WordPress.org.
‘sensei/woothemes-sensei.php’, // Sensei 1.x or Sensei 2.x Compatibility Plugin.
‘woothemes-sensei/woothemes-sensei.php’, // Sensei 1.x or Sensei 2.x Compatibility Plugin.
);
