trouble installing software

[StephenGriffies]

On my Mac I get an error with gem. I have MacOS HighSierra 10.13.5. Google turns up something similar, but my initial leads came up dry.

You need to prefix the command with sudo. It is writing into a shared system directory. I had to do this also.

Thanks for the "sudo" step. I got further. But there is still an error in the install "ERROR: Failed to build gem native extension.". Should I ignore?

You could try running it again. I seem to recall I had to run something twice (sorry for the vague instructions). This is so you can preview the site before pushing, but it is not strictly necessary. You can break fiddle an break it and just revert to a previous version. Obviously it is better to be able to preview any changes ... Cheers Aidan

Tried it again, with same error. I will move forward.

It seems this error is because you don't have Xcode command line tools installed.

Follow the instructions here:

http://osxdaily.com/2014/02/12/install-command-line-tools-mac-os-x/

to install just the command line tools in the first instance, and see if that fixes it.
