No plugin exists with handle "cookies"

[kellyannmcnamara01]

We've been using this plugin for about a week and everything has been fine. An hour ago we are now unable to install the plugin via command line or through the craft plugin store.

Problem:
Unable to install the plugin

Error message from the command line:
Nothing to install or update

Error message from Craft's plugin store:
Response: {"error":"No plugin exists with the handle \"cookies\"."}

Request:
Would like to be able to install the plugin again

Other Notes
We installed the plugin March 1, 2019. This was after the date that you updated the package name in this issue ticket

I had the same problem, and in my case the project config (Craft::$app->getProjectConfig() used with ./craft install/plugin) did not return all plugins.

./craft project-config/rebuild fixed it.

Yeah probably the plugin just isn't installed somehow.
