Using Environment Variables across files - GOPATH
问题 This is my first time coding in Go without using GOPATH. I have a go.mod file. I'm attempting to send an email through Sendgrid; I have a file which contains my SENDGRID_API_KEY called sendgrid.env . When trying to use the key within my main.go file, the value isn't being pulled through. fmt.Println(os.LookupEnv("SENDGRID_API_KEY")) // empty string fmt.Println(os.Getenv("SENDGRID_API_KEY")) // empty string I've also used 'LookupEnv' which returns false. Any help would be appreciated. 回答1: os
