Go build: “Cannot find package” (even though GOPATH is set)

Question

Even though I have GOPATH properly set, I still can\'t get \"go build\" or \"go run\" to find my own packages. What am I doing wrong?

$ echo $GO         


        

Answer 1

To be able to find your project's packages without installing it, (which is common during development), simply append project path to GOPATH.

• In terminal (Linux):
  First run: GOPATH=$GOPATH:/path/to/project
  Then go run main.go should be able to find packages from the project itself.
  Similar for Mac; for Windows the delimiter is ; not :.
• In Goland:
  Settings -> Go -> GOPATH, under Project GOPATH, add project path.
  Then Goland should be able to find packages from the project itself during development.
