安装byebug（7.0.0）时发生错误，并且捆绑程序无法继续

Question

When I run bundle install, I get this error:

In case the picture doesn't load, here is the error message: "An error occured while installing byebug (7.0.0), and bundler cannot continue."

I found a few answers that suggested making changes to the Gemfile, which I did and that did not work. After those unsuccessful attempts, I uninstalled rails and reinstalled it.

I am working on a macbook pro, osx yosemite version 10.10.5.

Answer 1

What version of XCODE are you using and do you have the command line tools extensions for it installed? Also, byebug is noted elsewhere has previously having compiler options that are unsupported by the xcode compilers. With xcode-5.1 you can turn these errors into warnings. Later versions may or may not permit this. See: Ruby Gem install Json fails on Mavericks and Xcode 5.1 - unknown argument: '-multiply_definedsuppress'
