I have added “Infiltrator” as a dependency to my locally developed package “SpinGauss”.  
However, it produced an error at precompilation stage.  
When I run `import Pkg; Pkg.precompile()` as suggested by the error log, I get the following:

> Failed to precompile  
> ERROR: LoadError: ArgumentError: Package SpinGauss does not have Inflitrator in its dependencies:
> 
> - If you have SpinGauss checked out for development and have  
> added Inflitrator as a dependency but haven’t updated your primary  
> environment’s manifest file, try `Pkg.resolve()`.
> - Otherwise you may need to report an issue with SpinGauss

This is really strange. The error says that I didn’t add “Infiltrator” to dependencies, although I just did.  
I tried to run `Pkg.resolve()` but it did not help. I also tried to delete “Manifest.toml” and [deps] section of “Project.toml” and add all the dependencies again, but I still get the same error.

How do I fix this?
