Hey Guys,

I am trying to understand the nameservice app tutorial. To do this I recreated a very similar application but changing just a few methods in order to try to better understand the code.

Running the make install command I have this error message:

make install  
–\> Ensure dependencies have not been modified  
GO111MODULE=on go mod verify  
all modules verified  
GO111MODULE=on go install -tags “” ./cmd/nsd

Makefile:3: recipe for target ‘install’ failed  
make: \*\*\* [install] Error 2

I tried to check the lines indicated but could not find any of these errors.

Any help would be welcome in order to resolve this issue.

Many thanks in advance

Hey,

Make this your module name in go.mod “module [github.com/Ohmere03/testapplication](http://github.com/Ohmere03/testapplication)”
