It determines the exact MacOS version 21 and Python version you have and uses that information to download 22 a database that has packages that are test and tried on that 23 combination. In other words: if something is in your Package Manager 24 window but does not work you are free to blame the database maintainer.</p> 25 26 <p>PackageManager then checks which of the packages you have installed 27 and which ones not. This should also work when you have installed packages 28 outside of PackageManager. 29 You can select packages and install them, and PackageManager will work 30 out the requirements and install these too.</p> 31 32 <p>Often PackageManager will list a package in two flavors: binary 33 and source. Binary should always work, source will only work if 34 you have installed the Apple Developer Tools. PackageManager will warn 35 you about this, and also about other external dependencies.</p> 36 37 <p>PackageManager is available as a separate application and also 38 as a function of the IDE, through the <tt>File->Package Manager</tt> menu 39 entry. </p> 40 41 <h2>Troubleshooting</h2> 42 43 <p>If package manager fails to open the database first check that you are 44 connected to the internet. If you are connected then the problem 45 could be that there is no database (yet?) for your version of Mac OS X. 46 You may be able to find an alternative 47 database that works for your system at 48 <a href="http://www.python.org/packman">http://www.python.org/packman</a>. 49 In the standalone Package Manager you can then open such an alternative database 50 with the <tt>File->Open URL...</tt> command, but you should realize that 51 you are now on untested ground.</p> 52 53 <p>Another potential problem source is that you are behind a firewall. This version 54 of PackageManager uses the Unix method of setting a firewall: you need to set the 55 environment variable <tt>http_proxy</tt> to <tt>"http://<i>proxyhost</i>:<i>port</i>"</tt>. 56 See <a href="http://developer.apple.com/qa/qa2001/qa1067.html">Apple Technical 57 Q&A QA1067</a> for instructions.</p> 58 59 </td> 60 </tr> 61 </table> 62 <hr> 63</body> 64</html>
