Three.js 使用blender导出三个JS会给我带来错误…（Linux ubuntu）

我用搅拌机做了一个模型。我用three.js导出。我犯了一些错误。我正在使用linux ubuntu。我想我用的是blender 2.62。导出时，会显示以下内容：

! Error
Traceback (most recent call last):

 File "/usr/lib/blender/scripts/addons/io_mesh_threejs/__init__.py" line 340, in execute 
    return io_mesh_threejs.export_threejs.save(self, context, **self.properties

    mesh.update(calc_tessface=true)

 TypeError: Mesh.Update(): was called with invalid keyword argument(s) (calc_tessface), expected (calc_edges)

有人知道怎么解决这个问题吗？我是否进入export_threejs.py并将calc_tessface更改为calc_Edge？？我该怎么办？我不想把事情搞砸
