The -e flag causes tidy to attempt to proceed despite errors
encountered while loading packages.

The -diff flag causes tidy not to modify go.mod or go.sum but
instead print the necessary changes as a unified diff. It exits
with a non-zero code if the diff is not empty.

The -go flag causes tidy to update the 'go' directive in the go.mod
file to the given version, which may change which module dependencies
