Why Does the Go Importer Show a \'Package Not Found\' Error, and How Can I Fix It?

Troubleshooting Go Importer: Package Not Found

When attempting to import a package using the Go importer, you may encounter an error indicating that the package is not found. While the documentation is limited, this error typically signifies that you have not downloaded the package.

Unlike standard Go packages like "time," the Go importer does not automatically fetch dependencies for you. To resolve this issue, you can manually fetch the package using:

go get -u github.com/onsi/ginkgo

Once the package is downloaded, the Go importer will successfully identify it.

Go Modules for Dependency Management

Go Modules provides a modern approach to managing dependencies. To enable Go Modules, initialize your project by entering:

$ GO111MODULE=on go mod init

Next, tidy up your dependencies by running:

$ GO111MODULE=on go mod tidy

This will verify your packages and download them accordingly. To install a specific package using Go Modules:

$ go install github.com/onsi/ginkgo

By utilizing either manual package downloading or Go Modules, you can effectively use the Go importer to parse types defined in your desired packages.
