这个问题已在 SO 中得到回答：https://stackoverflow.com/q/19916925/210336 （实际上那里存在许多未标记的重复项，这是我能找到的最古老的一个）。
答案摘录：
从：http://pydev.org/manual_101_install.html
重要要求
PyDev 现在需要 Java 7 才能运行。如果您没有 Java 7，更新过程可能看似成功，但 PyDev 不会显示在目标安装中。在尝试安装 PyDev 之前，请在关于 > 安装详细信息 > 配置中仔细检查您是否正在使用 Java 7 VM。
最新版本的 PyDev 需要 Eclipse 3.8 及以上版本（如果您需要使用早期版本的 Eclipse，请坚持使用 PyDev 2.8.x）。
你运行的是哪个版本的 Eclipse？我运行的是 Ubuntu 12.04，软件中心为我提供的是 Eclipse 3.7。
要在 Eclipse 中安装 2.8.x，请按照 bohrax 提到的进行操作：取消选择“仅显示可用软件的最新版本”并选择 2.8.x。
