Eclipse安装pydev

Eclipse安装pydev Installing with the update site Note: Instructions are targeted at Eclipse 3.5 and 3.6 To install PyDev and PyDev Extensions using the Eclipse Update Manager, you need to use the Help > Install New Software... menu (note that in older versions, this would be the 'Find and Install' menu). In the next screen, add the update site(s) you want to work with (See below for a list with the available update sites). Available update sites , ; Main: , ; Nightly builds: After entering the update sites, select the update site you entered or select "All available sites" and add a filter for PyDev, so that it shows the contents of all the update sites that have PyDev, then select what you want to install and click 'Next'. Then, UNCHECK the 'Contact all update sites during install to find required software' and press 'Next' again to confirm your selection. And finally, read the license agreement and if you accept, select the accept radio button and click 'Finish'. At that point, Eclipse should automatically download the plugin contents and present you to a dialog asking if you want to restart (to which you should say yes). Possible issue on download If you have any problem at this point with a message such as: An error occurred while collecting items to be installed No repository found containing: org.python.pydev/osgi.bundle/1.4.7.2843 No repository found containing: org.python.pydev.ast/osgi.bundle/1.4.7.2843 that might indicate that the mirror you selected is having some network problem at that time, so, please follow the same steps with another mirror. Installing with the zip file The available locations for the zip files are: , SourceForge download After downloading the zip file: Eclipse 3.4 and 3.5 Extract the contents of the zip file in the eclipse/dropins folder and restart Eclipse. Before Eclipse 3.4 Extract the contents of the zip file on top of Eclipse, making sure the plugins folder is extracted on top of the eclipse/plugins folder and the features is on top of the eclipse/features folder. After that, restart Eclipse with the '-clean' flag, so that Eclipse finds out about it. Checking the installation You can verify if it is correctly installed going to the menu 'window > preferences' and checking if there is a PyDev item under that. Uninstalling Follow the instructons below if at any time you wish to stop using the PyDev plugin (or any other Eclipse plugin): Eclipse 3.5 If you installed with the update site, go to the menu help > about > installation details then on the Installed Software tab, select the plugins you want to uninstall and click Uninstall. If you installed with the zip file, just remove the com.python.pydev and org.python.pydev features and plugins from the dropins folder. Before Eclipse 3.4 Go to the menu help > software updates > manage configuration, select the plugin and click 'disable', then, you have to restart Eclipse, go to the same place again and then click on 'remove' (note that you have a button in the menu that enables you to see the 'disabled' features). Common Install Problems Windows Vista/7 UAC (User Access Control) Eclipse 3.3 had issues with the Windows UAC, so, Eclipse must be run as Administrator to install a plugin on Eclipse 3.3. Corrupted install Eclipse sometimes is not able to correctly get the plugin, from the update site but will do no checking on whether it is really correct (no md5 checking), and when this happens, you'll usually get a ClassNotFoundException (similar to the example below). When that happens, you should uninstall it and reinstall again with the update site... if that still fails, you could try to get the zip files, as it will at least give you a warning when it is corrupt. Note that the chance of the files being corrupt in the server is pretty low, as that's something that's always checked in a new release -- but if you're suspicious about it, please ask in the forum, so that it can be double-checked. Also, there have been reports with that error where the only solution that has been consistent has been removing all previous versions of pydev and then installing the latest version. EXAMPLE Unable to create this part due to an internal error. Reason for the failure: The editor class could not be instantiated. This usually indicates that the editor's class name was mistyped in plugin.xml. java.lang.ClassNotFoundException: org.python.pydev.editor.PyEdit at org.eclipse.osgi.framework.internal.core.BundleLoader.findClass(BundleLoader.java:405) at org.eclipse.osgi.framework.internal.core.BundleLoader.findClass(BundleLoader.java:350) at org.eclipse.osgi.framework.adaptor.core.AbstractClassLoader.loadClass(AbstractClassLoader.java:78) at java.lang.ClassLoader.loadClass(ClassLoader.java:235) at org.eclipse.osgi.framework.internal.core.BundleLoader.loadClass(BundleLoader.java:275) ...
