Hi Ed,
Sorry to hear this is giving you the runaround.
It sounds like something is not fully installed correctly. These can be hard for us to diagnose, but I think it has to do with your compiler and related tools (see Ch. 4 in our User Manual if you haven’t looked at that yet). Here are some suggestions of issues we’ve seen people run into.
On Windows, when installing Rtools.exe, there may be a check box to modify the PATH, which should be checked.
On Mac, when installing Xcode, the command line tools need to be included. Also it may be necessary to launch Xcode once on its own before using it through nimble (it may take a password when first launched).
If you try reinstalling your C++ compiler based on the above points, you may then need to reinstall nimble.
Please let us know if you’re still stuck, and also let us know if one of these seems to solve your problem so we can amass experience about issues people are running into.
Thanks
Perry
