try to install dugways I get this Building native extensions. This could take a while... ERROR: Error installing dugway: ERROR: Failed to build gem native extension.

Do you have Xcode Developer tools installed? If not, try running xcode-select --install

After doing the install Xcode-select --install it worked. Thank You for the help.
