Solution to the issue of missing components in Eagle

Today I had this problem again: when trying to add components in Schematic view, there were no components from Eagle’s standard library. This issue sometimes shows up after an update.

The solution is very simple. All you need to do is go to Eagle’s Control Panel, scroll up to Libraries, right click, and select “Use All”.

Here’s a step by step video (in spanish, but you can ignore the narration).
