osx-mavericks

A recent upgrade to OSX Mavericks has broken my database connection for my Rails app. When I try to fetch from the database the server returns the following error: PG::ConnectionBad (could not connect to server: Connection refused Is the server running on host "localhost" (::1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused Is the server running on host "localhost" (127.0.0.1) and accepting TCP/IP connections on port 5432? could not connect to server: Connection refused Is the server running on host "localhost" (fe80::1) and accepting TCP/IP

I tried to install the command line tools on Mavericks following the steps in this very useful post > xcode-select --install but after a few short seconds I get the message This seems wrong. Does anyone know how to solve this problem? Whenever I navigate to the page that @Nikos M. is suggesting I get this message I followed @Rich's suggestion and I was able to download the package and install it which I wasn't able to do before, but I've found that I still don't have access to a lot of the commands that I should like arp or diskutil just to name two that I've encountered recently.

After updating to OS X 10.9 Mavericks I tried to start a Rails 3 app, but the connection to the PG database was not working. Checking on PGAdmin III, the database is still there and it works fine. So I tried to reinstall the pg gem: gem uninstall pg gem install pg But the last command doesn't succeed, and gives the following error: Building native extensions. This could take a while... ERROR: Error installing pg: ERROR: Failed to build gem native extension. /Users/XXX/.rvm/rubies/ruby-1.9.3-p194/bin/ruby extconf.rb checking for pg_config... yes Using config values from /usr/local/bin/pg_config

After upgrading to OSX Mavericks, I am getting this message in the terminal: /usr/bin/python: No module named virtualenvwrapper virtualenvwrapper.sh: There was a problem running the initialization hooks. If Python could not import the module virtualenvwrapper.hook_loader, check that virtualenv has been installed for VIRTUALENVWRAPPER_PYTHON=/usr/bin/python and that PATH is set properly. Try reinstalling pip and then reinstalling virtualenvwrapper (I had to go through these steps after upgrading to Mavericks): $ sudo easy_install pip $ sudo pip install --upgrade virtualenvwrapper Josh Antweiler

I already have matplotlib-1.2.1 installed as well as numpy-1.8.0 . Note - I am using system python with homebrew installed - I have $PYTHONPATH set so Python loads from /Library/Python/x.y/site-packages (where pip installs to). Here is the code for installing matplotlib (the configurations) BUILDING MATPLOTLIB matplotlib: yes [1.3.1] python: yes [2.7.5 (default, Aug 25 2013, 00:04:04) [GCC 4.2.1 Compatible Apple LLVM 5.0 (clang-500.0.68)]] platform: yes [darwin] REQUIRED DEPENDENCIES AND EXTENSIONS numpy: yes [version 1.8.0] dateutil: yes [using dateutil version 1.5] tornado: yes [tornado was

I'm trying to install the following gem versions on Mavericks libv8 (3.16.14.3) therubyracer (0.12.1) Obviously therubyracer gems depends on libv8. 1) Installing libv8 What is libv8? My bit of research seems to indicaite it's some sort of javascript library used by Google Chrome? I was having trouble installing it, but this great post had both my error and a well-explained answer on how to bypass it. So I installed libv8 with gem install libv8 -- --with-system-v8 It's my understanding that this installs the gem but uses my local system installation of the v8 library instead of... the version

I've been using Objective-C mixed with C++ in Qt without any issues; using .mm files where required. After upgrading my build machine to Mavericks, I initially noticed that the framework headers were missing, so installed the XCode command line tools, which fixed the issue. Now, I'm getting a problem compiling Objective-C files with errors complaining about code in the frameworks. For example: - System/Library/Frameworks/Foundation.framework/Versions/C/Headers/NSUserNotification.h:16:44: error: missing ',' between enumerators NSUserNotificationActivationTypeReplied NS_AVAILABLE(10_9, NA) = 3
