Trying to install the pg gem gives me errors. I'm using Ruby 1.9.3-p125 built using rbenv/ruby-build. I installed PostgreSQL using the one-click installer.

I use an admin account for the development. But every time I compile to a device Xcode is asking for admin username & password. I googled the issue. But none of the solutions worked.

PS. I am using - and in the project I am working on, I must use ruby v1.8.7.

In the OSX terminal : du -h | sort -nr -bash: sort: command not found which sort /usr/bin/sort The weird thing is: I tried reproducing the error and it seems to be totally random. My PATH echoed: /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/git/bin:/usr/texbin:/Users/sytycs/.rvm/bin This only occurs when piping and happens with grep , more , less etc. Any idea what is causing this? That space is not a space. Erase and replace it. Michael Trojanek This likely happens because you use a keyboard layout with a non-US layout (happened to me too). On German layouts, the pipe

When trying to "import cv" in python I get: "ImportError: No module named cv". This question has appeared in many forms, but I haven't found the answer that helps. On my Mac OS X Lion, among many other ports, I have run: sudo port install python27 and sudo port install opencv +python27 Running: port select python I see: "python27 (active)" And running: port installed opencv I see: "opencv @2.3.1a_1+python27 (active)" What else should I check? Thanks. Pete I had this same problem. It looks like a (maybe?) bug with the OpenCV install script for 2.3.1a. It will not create the Python bindings

I use plain Vim with ruby support on Lion (installed by gist ). I am using ruby with rbenv so my path looks like /users/me/.rbenv/shims:..... From within vim the path is :!echo $PATH > usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Users/fb/.rbenv/shims:....

So how can I access my ruby 1.9.3 in ~/.rbenv/shims instead the system ruby in /usr/bin ? This is a known problem introduced by
