Understanding the Problem

Before diving into the solution, let's first understand the cause of the problem. The error missing go.sum entry for module providing package occurs when there is a discrepancy between the dependencies listed in your go.mod file and the entries in your go.sum file. This can happen when a new dependency is added, a dependency is updated, or there is some inconsistency in the go.sum file.

The go.sum file is responsible for maintaining the integrity of the dependencies in your Go module. It contains the checksums for each dependency, which ensures that the exact version of the dependency is used at all times.

Step-by-Step Solution

To resolve the missing go.sum entry for module providing package error, follow these steps:

Check your go.mod file for inconsistencies: Ensure that your go.mod file has the correct module path and that all dependencies are listed with the appropriate version numbers.

Run go mod tidy: Execute the go mod tidy command in your terminal. This command ensures that your go.mod and go.sum files are consistent with each other by updating the go.sum file with the correct checksums for your dependencies. If there are any issues with your go.mod file, go mod tidy will attempt to fix them.

go mod tidy

Verify your dependencies: Run the go mod verify command in your terminal to ensure that the dependencies in your go.sum file have not been tampered with.

go mod verify
  1. Build or test your module: After running the above commands, try building or testing your Go module. If you still encounter the same error, repeat the steps, ensuring that your go.mod file is correct.


How do I create a go.mod file for my Go module?

To create a go.mod file for your Go module, navigate to the root directory of your module and run the following command:

go mod init <module-name>

Replace <module-name> with the desired name for your module.

What is the purpose of the go.sum file?

The go.sum file is used to maintain the integrity of your Go module's dependencies. It contains the cryptographic checksums for each dependency and its version, ensuring that the exact version of the dependency is used during builds.

How do I add a new dependency to my Go module?

To add a new dependency to your Go module, simply import the package in your code and run go mod tidy. This will automatically update your go.mod and go.sum files with the new dependency.

How do I update a dependency in my Go module?

To update a dependency in your Go module, you can manually change the version number in your go.mod file or use the following command:

go get -u <package-name>@<new-version>

Replace <package-name> with the name of the package you want to update and <new-version> with the desired version.

How do I remove a dependency from my Go module?

To remove a dependency from your Go module, first remove all imports of the package from your code. Then, run go mod tidy to automatically update your go.mod and go.sum files, removing the dependency.
