问题 This is a forked problem off of this question: flac: "ERROR: input file has an ID3v2 tag" (it doesn't). I've solved the initial issue there but that didn't resolve one problem I was having, so I'm going to introduce it separately here. I'm using a Ruby gem called speech2text to convert an audio file into (approximated) text. Calling it on the command line works fine (Mac Terminal).

问题 I recently started using XAMPP on Mac and it installed the "lampp" folder under "Shared" and showing as an IP address in Finder. So I can access the files via Finder but I'm unable to cd into the folder via Terminal. The Shared folder is simply not visible. I tried /Volumes to see all volumes, but "lampp" wasn't listed, as well mounting it somehow but that also didn't work. Any ideas? It's so odd that I see the folder in Finder but not in Terminal! 回答1: I had the same problem the route for
