I suggest you take a look at rvm. You can then set it as default with rvm use 1.9.3 –default But if you are happy with your homebrew install. Then just change the precedence of directories in the PATH Here is my /etc/paths # homebrews should always take precedence /usr/local/bin # the default stack /usr/bin … Read more
Short answer is you can grab RVM master branch (not stable) to build it with LLVM (not gcc, I mistyped initially). It has appropriate patches to make 1.9.3-p125 to run (at least better) with Xcode 4.3.1 by default. I provided the patch. If you already installed RVM, rvm get head will install the master branch. … Read more
Try the following: Install the latest Xcode. From Xcode’s Preferences menu, install the Command Line Tools (Downloads/Components tab).
It’s evident that you’ve managed to mess up your PATH variable. (Your current PATH doesn’t contain any location where common utilities are located.) Try: PATH=/bin:/usr/bin:/usr/local/bin:${PATH} export PATH Alternatively, for “resetting” zsh, specify the complete path to the shell: exec /bin/zsh or exec /usr/bin/zsh
This happens when a piped program (e.g. grep) closes the read pipe before the previous program is finished writing the whole page. In curl “url” | grep -qs foo, as soon as grep has what it wants it will close the read stream from curl. cURL doesn’t expect this and emits the “Failed writing body” … Read more
It’s a PATH issue. Mac OSX Lion includes Postgresql in the system now. If you do a which psql you’ll likely see usr/bin/psql instead of usr/local/bin/psql which is HomeBrew’s correct one. If you run brew doctor you should get a message stating that you need to add usr/local/bin to the head of your PATH env … Read more
From the Apple Developer Forum (account required): “The compiler and linker are capable of using features and performing optimizations that do not work on older OS versions. -mmacosx-version-min tells the tools what OS versions you need to work with, so the tools can disable optimizations that won’t run on those OS versions. If you need … Read more
This is a chicken and the egg problem. The table needs to know the row height because that determines where a given view will lie. But you want a view to already be around so you can use it to figure out the row height. So, which comes first? The answer is to keep an … Read more
This answer was edited multiple times and now contains several alternative solutions. Try the simple “Edit 3” solution first. Ruby 1.9.3-p125 and later have official support for clang, so if you are installing such a version you should not need GCC. If you’re installing an older version of Ruby, read on. To compile Ruby with … Read more
First, one thing to recognize about OS X is that it is built on Unix. This is where the .bash_profile comes in. When you start the Terminal app in OS X you get a bash shell by default. The bash shell comes from Unix and when it loads it runs the .bash_profile script. You can … Read more
