Installing PyDev into Eclipse

Question

I've read information from 7 different sites and read a number of posts regarding installing PyDev using eclipse.

Every time I run the add new software as instruction, I encounter the following error

Error:

An error occurred while collecting items to be installed

How can I fix this?

Answer 1

The problem is in Eclipse 3.7 (it can't read the signature done in the PyDev plugin -- this is a bug fixed on Eclipse 3.8).

So, in short, you need Eclipse 3.8 onwards in order to install PyDev using the update site (and also, PyDev now requires java 7 -- as a note, LiClipse: http://brainwy.github.io/liclipse/ which is a commercial counterpart of PyDev is standalone and has all requisites builtin).
