Invisible folder after usage of trash-cli
As you have seen by running ls and rm (and viewing in Finder), the /Users/admin/anaconda folder and its contents are no longer present in the filesystem.

locate uses a database that is updated approximately once a week in OS X, so deleting a file/folder and immediately (or even later that day or week) using locate will not reflect its removal.

You can manually update the locate database by running this command:

sudo /usr/libexec/locate.updatedb


See the locate.updatedb(8) man page for further information.
