Hi,

I am new to cosmos and I am trying the [Getting Started | Cosmos SDK Tutorials](https://tutorials.cosmos.network/nameservice/tutorial/00-intro.html).

However, I see to run into a compile error [uploading files · Rajakavitha1/nameservice@3c0ff2d · GitHub](https://github.com/Rajakavitha1/nameservice/actions/runs/433288582)

Also on MacOS I am running into:  
📦 Installing dependencies…

```
🛠️ Building the app...

cannot build app:

# github.com/keybase/go-keychain

cgo-gcc-prolog:203:11: warning: 'SecTrustedApplicationCreateFromPath' is deprecated: first deprecated in macOS 10.15 - No longer supported [-Wdeprecated-declarations]

/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/System/Library/Frameworks/Security.framework/Headers/SecTrustedApplication.h:59:10: note: 'SecTrustedApplicationCreateFromPath' has been explicitly marked deprecated here

# github.com/Rajakavitha1/nameservice/x/nameservice/types

x/nameservice/types/key.go:11:2: RouterKey redeclared in this block

previous declaration at x/nameservice/types/MsgSetName.go:8:19

waiting for a fix before retrying...

```

When I try to build I get this error:

```
github.com/Rajakavitha1/nameservice/x/nameservice/client/cli

../../x/nameservice/client/cli/txWhois.go:55:52: cannot use cliCtx.GetFromAddress() (type "github.com/cosmos/cosmos-sdk/types".AccAddress) as type string in argument to "github.com/Rajakavitha1/nameservice/x/nameservice/types".NewMsgSetName

```

Can someone please help?

Thanks in Advance
