好的！你希望这段 Maya 脚本在 **Python 2.7 环境下也能运行**，而当前的代码是基于 Python 3 编写的（特别是使用了 `from PySide2 import QtWidgets, QtCore`）。 在 Maya 2018 及更早版本中，**默认使用的是 Python 2.7**，而 PySide2 是从 Python 3 开始支持的。因此，我们需要对 UI 部分进行兼容性调整，使用 **PySide（即 PySide1）** 来替代 PySide2。 --- ## ✅ 主要改动点 | 项目 | Python 3 + PySide2 | Python 2.7 + PySide1 | |------|---------------------|-----------------------| | 导入模块 | `from PySide2 import QtWidgets, QtCore` | `from PySide import QtGui, QtCore` | | 文件对话框 | `QtWidgets.QFileDialog.getExistingDirectory()` | `QtGui.QFileDialog.getExistingDirectory()` | | 按钮绑定 | `lambda x: func()` | `lambda *args: func()` | | 其他 UI 类型 | `QtWidgets.*` | `QtGui.*` | --- ## ✅ 兼容 Python 2.7 的完整代码（单面板版） ```python # -*- coding: utf-8 -*- import maya.cmds as cmds import maya.mel as mel import os try: from PySide import QtGui, QtCore PYSIDE_VERSION = 1 except ImportError: try: from PySide2 import QtWidgets as QtGui from PySide2 import QtCore PYSIDE_VERSION = 2 except ImportError: raise ImportError("Neither PySide nor PySide2 found.

Launch Unified GUI create_unified_ass_tool_gui() ``` --- ## ✅ 使用说明（Python 2.7） 1. **确保你的 Maya 使用 Python 2.7**（Maya 2017 及以前版本） 2. **安装 PySide 1.2.4**（适用于 Python 2.7） - 如果 Maya 没有内置 PySide，你需要手动安装： ```bash pip install PySide==1.2.18 ``` 3. 将脚本保存为 `arnold_ass_unified_tool_py2.py` 4. 在 Maya 脚本编辑器中运行： ```python import arnold_ass_unified_tool_py2 arnold_ass_unified_tool_py2.create_unified_ass_tool_gui() ``` --- ### ✅ 相关问题
