Normally I download a Silverstripe TAR file, unzip and run installer. Today I thought I'd use some newly-found knowledge and install using Composer. So I copied install path, fired up Terminal on my Mac and ran the instruction. I got the following error:
Silverstripe composer [ErrorException] mkdir(): Permission denied
First I thought it was because I was trying to overwrite the empty folder that I had already set up. So I deleted the folder and tried again with the same result. Obviously it's a write problem -- can anybody tell me what I'm doing wrong?
