I found (what I think is) a simple GO project to play with as a learning exercise:
https://intersog.com/blog/how-to-write-a-custom-url-shortener-using-golang-and-redis/ The second step fails immediately. with the aforementioned error message. I'm using GO version 1.15.6 $GOPATH is undefined. Here's the content of ~/go Joes-iMac:go joe$ pwd /Users/joe/go Joes-iMac:go joe$ ls bin go.mod pkg src Joes-iMac:go joe$ more go.mod module urlShorter go 1.15 [eof] So, I googled for the error message. I find lots of hits, but no clear explanation of why the error message, but most importantly, no clear explanation of how to fix... Help please!
