python eclipse+pydev(An error has occurred when creating this preference page)

Eclipse 安装pydev :

1. Help->Install New Software ->add ->Location=http://pydev.org/updates
2. 点击pydev左边的小三角勾选pydev for eclipse
3. 开始安装，完成后重启eclipse

遇到问题：Window -> preferences -> pydev

点击pydev或其子项 右边出现An error has occurred when creating this preference page.

且弹出对话框(如下图)：

Unable to create the selected preference page.

 An error occurred while automatically activating bundle org.python.pydev (927).

原因分析：pydev插件版本较高，不兼容

解决方法：

1.卸载 Help->Install Details->installed software->pydev for eclipse->下方的uninstall

2.重新安装旧版pydev，Location=https://dl.bintray.com/fabioz/pydev/old
