Question

Following Michael Hartl’s Rails 2.3 tutorial. Excellent, so far, but I am stuck on the prep for the testing environment on page 87. Can’t get the autotest-fsevent to install.

iMac i7 running Snow Leopard.

Typing the command in the Title, above, I get the following error message:

bash-3.2$ sudo gem install autotest-fsevent -v 0.1.1
Building native extensions. This could take a while…
ERROR: Error installing autotest-fsevent:
ERROR: Failed to build gem native extension.

    /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb

mkmf.rb can’t find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/ruby.h

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/sys-uname-0.8.6 for inspection.
Results logged to /Library/Ruby/Gems/1.8/gems/sys-uname-0.8.6/ext/gem_make.out

I’ve tried downloading a ruby 1.8.7 fresh install to get the header files, but that has not seemed to work. Copied them to the path in bold, above.

Any help will be greatly appreciated.

Answer 1

“Do you have Xcode installed?”

Thanks for checking. In fact, I didn’t realize that there was a difference between Xcode in the standard Snow Leopard install and the one downloaded from the Apple Developer Network. I have installed the full Xcode and the problem is now solved.

Cheers,
