In order to run or build a Go project, we need to have access to the Go binary and its libraries. A typical installation of Go (instructions can be found at https://golang.org/dl/) on Unix-based systems will place the Go binary at /usr/bin/go. However, it is possible to install Go on a different path. In that case, we need to set the GOROOT environment variable to point to our Go installation path and also append it to our PATH environment variable.
