How can I fix this?

Answer 1

Not sure if this will fix the problem, but one workaround solution may be to uncheck "Show only the latest versions of available software" on the install dialog box where you choose the version of PyDev to install.

Alternatively, you could manually install PyDev by downloading the zip file and extracting it to the eclipse/dropins folder.

You can find the latest version of PyDev here: http://sourceforge.net/projects/pydev/files/

The second solution is as noted in the PyDev manual: http://pydev.org/manual_101_install.html

Hopefully one of these approaches fixes the issue. :)

Answer 2

I was having problems with installing all versions of PyDev from 3.0 onwards while using Ubuntu, even when using the zip file supplied on the PyDev website for a while, but here is the solution to get it working.

Up to date versions of Eclipse may complete the PyDev installation using Eclipse's install feature with "http://pydev.org/updates", but even though installed PyDev will do nothing. (You can skip to step 2 if you are in this situation) Older versions of Eclipse will show the above error. However, both old (at least going as far back as the version on the Ubuntu Software Center, 3.7.2) and new versions can use PyDev 3.0+ perfectly if you follow these instructions.

Step 1:

Go to the (PyDev website) and download the zip file for Pydev 3.0 or higher.

Navigate to ~/.eclipse/org.eclipse.platform_VERSION/ (in Ubuntu, not sure where the Eclipse folder would be in Windows) and create a folder called "dropins". Copy the contents of the downloaded zip file to this new folder.

Step 2:

PyDev will now be installed, but wont do anything until you download Java 7, so you need to type the following commands into a terminal:

sudo add-apt-repository ppa:webupd8team/java

sudo apt-get update

sudo apt-get install oracle-java7-installer

sudo apt-get install oracle-java7-set-default

If you are using Windows you should probably be able to just download and install Java 7 from the Oracle website and stop here.

Step 3:

Java 7 will now be installed, but it is possible that Eclipse will no longer start. If this is the case you need to type the following into the terminal on 32-bit systems:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86/

Or the following on 64-bit systems:

ln -s /usr/lib/jni/libswt-* ~/.swt/lib/linux/x86_64/

PyDev 3.0+ should now be working fully in Eclipse!
