GoSublime: goimports doesn't run automatically on save

Hi, I’m having trouble running goimports automatically when I save a file on Sublime Text 3. It doesn’t auto format (gofmt) or do any goimports tasks.

Hi, I’ve installed correctly GoSublime + goimports

which goimports
/Users/fabrice/workspace/Go/bin/goimports

I’ve also set correctly my GOPATH and PATH :

echo $GOPATH
/Users/fabrice/workspace/Go

I’ve set my GoSublime custom config like that :

{
  "env": {
    "GOPATH": "/Users/fabrice/workspace/Go"
  },
  "fmt_cmd": ["goimports"]
}

Any advice?
