我的 Eclipse 为什么不能编辑 Python 文件

Debian 系统，安装 Eclipse 和 pyDev 插件，可不能编辑 Python 文件
错误如下：

1. Unable to create this part due to an internal error. Reason for the failure:
   
2. The editor class could not be instantiated. This usually indicates that the
   
3. editor's class name was mistyped in plugin.xml.
