Go language custom package import problem and solution
Go language beginners often encounter the problem of failing to import custom packages. This article will provide an effective solution to this problem.
Problem description
When learning the Go language package mechanism, many developers will encounter error prompts that custom packages cannot be imported.
Solution
This problem is usually related to the configuration of the Go Modules mechanism. Understanding Go Modules is the key to solving problems. The solution is given directly below:
First, execute the following command in the root directory of your project to initialize the Go Module:
go mod init your_module_name
Replace your_module_name with the module name of your project (for example: myproject ).
Then, make sure your custom package path is correct and use the correct import path in your main program:
package main
import (
"fmt"
"your_module_name/your_package" // Replace with your module name and package name)
func main() {
fmt.Println(your_package.YourFunction()) // Replace with your package function}
Finally, execute the following command to update and organize your module dependencies:
go mod tidy
Then run your Go program: go run main.go (or your main program file name).
Through the above steps, you should be able to successfully import and use your custom Go package. Make sure your package structure is consistent with the import path.
