问题 I have installed ruby 1.9.3 using hombrew brew install ruby But default 1.8.7 is still used. How can I switch osx to use 1.9.3 as default ruby? 回答1: 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 /bin /usr/sbin /sbin This is important

问题 This question may look like a duplicate of: How to uninstall postgresql on my Mac (running Snow Leopard) however, there are two major differences. I'm running Lion and I'm trying to uninstall PostgreSQL 9.0.4. I've looked at the last question and the link that it referenced, but I did not find a file called "uninstall-postgresql" when I run this command: sudo find / -name "*uninstall-*" So, I assume this means that the uninstall process for 9.0.4 is different than that of 8.x. I've seen a

问题 I'm using RVM to install it and it gives me this error: The provided compiler '/usr/bin/gcc' is LLVM based, it is not yet fully supported by ruby and gems, please read `rvm requirements`. I'm on Lion 10.7.3 and I have Xcode 4.3.1. 回答1: 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

问题 It works ok as a single tool: curl "someURL" curl -o - "someURL" but it doesn't work in a pipeline: curl "someURL" | tr -d '\n' curl -o - "someURL" | tr -d '\n' it returns: (23) Failed writing body What is the problem with piping the cURL output? How to buffer the whole cURL output and then handle it? 回答1: 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

问题 I have an application with a view-based NSTableView in it. Inside this table view, I have rows that have cells that have content consisting of a multi-row NSTextField with word-wrap enabled. Depending on the textual content of the NSTextField , the size of the rows needed to display the cell will vary. I know that I can implement the NSTableViewDelegate method - tableView:heightOfRow: to return the height, but the height will be determined based on the word wrapping used on the NSTextField .

问题 I have to version of PHP installed on my lion osx /opt/local/bin/php (5.3.12) /usr/bin/php (5.3.10) When I try to install php modules using port , it refers to /opt/local/bin/php (5.3.12) But when I start the web server the apache is using /usr/bin/php because if I look to the phpinfo on the apache webserver it tells me PHP Version 5.3.10 .
