```go: finding github.com/getwagz/go-sdk v1.38.1

go: error loading module requirements

This is the latest release of the github.com/getwagz/go-sdk and in my go.mod file, it is req

@aesherman is github.com/getwagz/go-sdk a public repository?

Can you try with the tip version of Go? It might work better, or might give a better error message.

An easy way to get tip is go get golang.org/dl/gotip && gotip download, and then you can do gotip get github.com/getwagz/go-sdk.

If that does not help, can you try gotip get -x -v github.com/getwagz/go-sdk?

[aesherman]

To answer a question I saw... github.com/getwagz/go-sdk _is_ a private repo that I have access to. Does something different need to be configured for modules in order to get it to work with private repos?

I fixed the issue by changing https to ssh in my gitconfig. I also discovered that the case must match in the paths from github, go.mod, & the import in the actual source. Thanks
