The error missing go.sum entry for module providing package occurs in Golang when your go.mod file does not match the source code in your module. You must update the go.mod file with the dependencies you use in your code.
To fix the missing go.sum entry for module providing package error, run the go mod tidy command. The go mod tidy command goes through the go.mod file to resolve dependencies:
- Delete the packages that are not needed
- Download those needed
- Update the go.sum
The go mod tidy command ensures that the go.mod file matches the source code in the module. It adds any missing module requirements necessary to build the current module’s packages and dependencies
The go mod tidy command removes requirements on modules that don’t provide relevant packages, adds missing entries to go.sum, and removes unnecessary entries.
Another solution is to run go get command for each missing package, as the error message suggests.
