After running...
go run main.go
I get this error
go : The term 'go' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify
that the path is correct and try again.
SOLVED: Go to visual studio code (assuming this is installed) ctrl + shift + p to open command window type
Go: current GOPATH
this should give you a path create a system environment variable named GOPATH and add that path into that variable.
Make sure the system environment variables are set to:
GOPATH is set (in my case) to C:\Users[username]\go
GOROOT is set to C:\go\
IDE is Visual Studio Code.
