Like a lot of other designers & developers, I run Mac OS X & Rails—with all the dependencies that implies. In the past, I’ve been burned by OS X upgrade incompatibilities (upgrading to 10.7 was particularly painful in fact), so now I’m not as keen to upgrade to the latest & greatest as soon as it comes out.
Which brings me to 10.8, or “Mountain Lion”. I installed this on my laptop & it throughly munged the system. What’s worse, with the move & redesign, I had little time to fix it: so it remained seriously broken until about a month or two ago. This article helped the situation greatly.
However, when I finally got around to installing Mountain Lion on the laptop, using the notes above, of course the damned thing failed, but in a new and interesting(?) way. I had upgraded the system, reinstalled XCode & its command-line tools, and went to install rvm:
rvm reinstall 1.8.7 --without-tcl --without-tk
But I received the error:
ERROR: The autodetected CC(/usr/bin/gcc-4.2) is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`, and set CC=/path/to/gcc .
So I looked at “rvm requirements”. It suggested I run
rvm install 1.8.7, but this caused the same error message. Rooting around, I saw mention of “rvm notes”, which suggested that I run
rvm get head && rvm reinstall 1.8.7. That did it!
After that I went into every local copy of Rails apps to trigger acknowledgement of the new rvm setup, and to re-trigger bundling in order to sort out all local gems. All sorted!
I also deal with a few PHP apps. It turns out that the httpd.conf files no longer enable PHP, and that you need to do so. Find the httpd.conf file in
/etc/apache2/ & uncomment
LoadModule php5_module libexec/apache2/libphp5.so (line 116 in my version of the conf). In addition, scroll down to configure the features for
/Library/WebServer/Documents & edit for the following (line 209):
<Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory>
DirectoryIndex, ensure you add
index.php (line 231), so that php files will be served. Restart Apache (
sudo apachectl restart) Sorted! Many thanks to this article which helped with the PHP side of things.
