How to Import Specific Package Versions in Go?

Importing Specific Package Versions in Go

In Go, installing a specific version of a package involves following a different approach compared to npm. The go get command does not support versioning out of the box. However, Go 1.11 introduces a new feature called go modules that enables versioned dependency management.

To install a specific version of a package using go modules, follow these steps:

1. Initialize a module:

   go mod init .

2. Edit the go.mod file to add the dependency with the desired version:

   go mod edit -require github.com/wilk/[email protected]@<version>

3. Refresh dependencies. This may require fetching the module graph and downloading packages:

   go get -v -t ./...  

4. Build the application:

   go build

5. Install the compiled binary:

   go install 

After completing these steps, you can import the specific version of the package in your code:

import (
    express "github.com/wilk/[email protected]"
)

Go modules provide a convenient way to manage package versions, ensuring that your application uses the correct version of each dependency. For more information on Go modules, refer to the official documentation: https://github.com/golang/go/wiki/Modules.
