"vagrant plugin install vagrant-parallels" fails!

Below is the output of my try to install vagrant-parallels.

Do note that I have a very clean install (reformatted system disk) of High Sierra. I ran Sierra or lower the last time I did this.

caused by misconfigured plugin installations or transient network

I also tried the same with a "sudo" infront, but that didn't help. Exactly the same result.

Should I bug this on GitHub ?

I removed and reinstall Xcode as a test, but same result.

 

Oh that (beeeep) Xcode license agreement!!! Im not a Mac developer so I in general do not run xcode.

Anyhow, after agreeing to xcode the installation worked fine.

Note that is is "xcodebuild -license" that you need to run in a shell.

on: http://parallels.github.io/vagrant-parallels/docs/installation/ it would be very helpful if under "Requirements", "Make sure you have installed and accepted the xcode license, which is done by running 'xcodebuild -license' in a shell." were added.

 

@tombensve Thank you for posting the solution!

That issue is caused by the nokogiri gem, which is installed automatically as a dependency of "vagrant-parallels" plugin.
That appeared not so long time ago, because previously nokogiri was bundled into a Vagrant package, so no compilation were needed on the target machine.

Due to a specifics of nokogiri, it compiles some libs on the target machine during the installation, so it requires some command line tools like "make" and C compiler to be available. These are absent by default on clean Macs, but that's actually could be solved once by running "xcode-select --install" or "xcodebuild --license" (if XCode.app is installed).

Anyway, you're right that we need to mention that in our docs. I'll manage to do add such notice there soon
