   Unable to run dlv version
2. What version of Go are you using? (go version)?

go version go1.12.7 darwin/amd64

1. What operating system and processor architecture are you using?
   Mojave - 10.14..6
   2.2 GHz Intel Core i7

2. What did you do?

3. Clone the repo
4. make build and make install

$ make build
go build "-ldflags=-s -X main.Build=4779218a8354d2facdbf2c48263c4144be330ca0" github.com/go-delve/delve/cmd/dlv

$ make install
go install "-ldflags=-s -X main.Build=4779218a8354d2facdbf2c48263c4144be330ca0" github.com/go-delve/delve/cmd/dlv

 $ dlv
-bash: dlv: command not found

1. What did you expect to see?

dlv should be found and work

1. What did you see instead?

-bash: dlv: command not found

Following my go env.

Following my env vars setup.

export GOPATH=$HOME/go
export GOROOT=/usr/local/go
export PATH=$GOPATH/bin:$PATH

If I go to the GOPATH/bin it works

However, why it is not working from any place by running just dlv? Is it missing something in the setup?

$ ./dlv

Delve is a source level debugger for Go programs.

Delve enables you to interact with your program by controlling the execution of the process,
evaluating variables, and providing information of thread / goroutine state, CPU register state and more.

The goal of this tool is to provide a simple yet powerful interface for debugging Go programs.

Pass flags to the program you are debugging using `--`, for example:

`dlv exec ./hello -- server --config conf/config.toml`

Usage:
  dlv [command]

Available Commands:
  attach      Attach to running process and begin debugging.
  connect     Connect to a headless debug server.
  core        Examine a core dump.
  debug       Compile and begin debugging main package in current directory, or the package specified.
  exec        Execute a precompiled binary, and begin a debug session.
  help        Help about any command
  run         Deprecated command. Use 'debug' instead.
  test        Compile test binary and begin debugging program.
  trace       Compile and begin tracing program.
  version     Prints version.

Flags:
      --accept-multiclient   Allows a headless server to accept multiple client connections.
      --api-version int      Selects API version when headless. (default 1)
      --backend string       Backend selection (see 'dlv help backend'). (default "default")
      --build-flags string   Build flags, to be passed to the compiler.
      --check-go-version     Checks that the version of Go in use is compatible with Delve. (default true)
      --headless             Run debug server only, in headless mode.
      --init string          Init file, executed by the terminal client.
  -l, --listen string        Debugging server listen address. (default "127.0.0.1:0")
      --log                  Enable debugging server logging.
      --log-dest string      Writes logs to the specified file or file descriptor (see 'dlv help log').
      --log-output string    Comma separated list of components that should produce debug output (see 'dlv help log')
      --wd string            Working directory for running the program. (default ".")

Additional help topics:
  dlv backend Help about the --backend flag.
  dlv log     Help about logging flags.

The error was in the env vars. Following the fix.

export GOPATH=$HOME/go
export GOROOT=/usr/local/Cellar/go/1.12.7/libexec
export PATH=$GOPATH/bin:$PATH
export PATH=$PATH:$GOROOT/bin

You can set your export (GOPATH and GOROOT)following the output of the command:
$ go env
