In the root folder where your extension is located (or its parent), there is a .pem file. Simply delete it.

When you try to Pack Extension it creates a private key with the extension of .pem. Follow this link:

https://stackoverflow.com/questions/50615890/what-is-the-chrome-extension-pem-file-for

This is because you executed extension, it is located in your parent folder. It will appear once you execute it. You need to delete it. enter image description here

This can be a one unique key only. So when you execute it again, it will throw again as already a private key exists.

Bumping this thread with a (possible) fix for others : the extension folder name must not contain spaces. E.g. change My Extension Folder to MyExtensionFolder.

I was dealing with that issue too. I changed the root folder name (that contained my manifest and js files) from "extension" to something else like "chromeext" and I was able to pack the extension successfully.
