Using Go Importer: Troubleshooting Missing Packages
When attempting to use the Go importer to parse package types, it's possible to encounter an error stating that the package cannot be found. This error can arise for several reasons.
Mistake #1: Package Not Downloaded
The Go importer requires that the package you're trying to parse is already downloaded. Unlike some package management systems, the importer does not automatically handle dependency downloading.
Solution:
Manually download the package to your Go path using go get:
go get -u github.com/onsi/ginkgo
Additional Mistake #2: Go Modules Not Initialized
If you're using Go modules, you need to initialize your project with go mod init and run go mod tidy to configure dependency handling.
Solution:
Follow these steps to use Go modules:
$ GO111MODULE=on go mod init
$ GO111MODULE=on go mod tidy
$ go install github.com/onsi/ginkgo
After these steps, the Go importer should be able to find and parse the desired package.
