cannot find package in any of GOROOT / GOPATH Go Origin: Application & API Last updated 4 Nov 2026

Go: cannot find package "github.com/pkg/errors" in any of: /usr/local/go/src/github.com/pkg/errors (from $GOROOT) /go/src/github.com/pkg/errors (from $GOPATH)

Go could not locate an imported package — it is not downloaded, the module is not initialised, or GOPATH mode is in effect.

Seen on: Go

Meaning

In module mode run go mod init and go mod tidy (or go get pkg). The GOROOT/GOPATH wording means Go is running in legacy GOPATH mode (GO111MODULE=off or no go.mod). Ensure a go.mod exists in the project root and that GO111MODULE is not off.

Common causes

  • No go.mod in the project
  • GO111MODULE=off
  • Dependency not downloaded
  • Typo in the import path
  • Vendor directory out of date

⚡ Quick fix

  1. go mod init example.com/app && go mod tidy
  2. Unset GO111MODULE or set on
  3. go get github.com/pkg/errors

Detailed fix by platform

Go

  1. go env GO111MODULE GOFLAGS GOPATH shows the active mode

How to diagnose

  1. Mode — go.mod present?
  2. Env — GO111MODULE?
  3. Path — Import spelled right?
