OSX: Maya Python Qt 与系统库冲突
OSX: Maya Python Qt conflict with system libraries
我正在尝试解决导致 Maya 崩溃的 Qt 库冲突问题。当我从终端 运行 Maya 时，我得到：
objc[4152]: Class QCocoaColorPanelDelegate is implemented in both /Applications/Autodesk/maya2016/Maya.app/Contents/MacOS/QtGui and /usr/local/lib/QtGui.framework/Versions/4/QtGui. One of the two will be used. Which one is undefined.

我的解决方法是隐式设置指向 Qt 库的 PYTHONPATH 环境变量：
/Applications/Autodesk/maya2016/Maya.app/Contents/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages
但这会导致其他使用 Qt 的应用程序 link 到 Maya 的自定义 Qt 构建，从而产生另一个冲突（不同的构建和 Python 版本）。
我猜这是一个 OSX 特定的问题。如何强制应用程序 运行 自己的 Qt 库？
编辑：
我删除了与 brew 一起安装的 Qt、PySide 和 Shiboken 包，以检查它们是否被 Maya 拾取。在没有设置 PYTHONPATH 的情况下，PySide 仍然从系统目录中获取：
import PySide
PySide.__file__
# Result: /usr/local/lib/python2.7/site-packages/PySide/__init__.pyc #
我今天遇到了同样的问题，已经解决了。所以这可能会有所帮助。
首先从 Maya 内部检查您的 sys.path：
for p in sys.path:
print p
您现在应该看到它列出的是错误的 /usr/local/lib/python2.7/site-packages/
几个原因：
您正在从命令行设置配置文件（.bashrc、.profile、.zshrc ...）中的 PYTHONPATH 和 运行 Maya。在这种情况下，您有两种选择。从您的配置文件中删除 PYTHONPATH，或者在 运行 Maya、
之前添加一个替您完成此操作的别名
沿着这些线的东西：
alias maya=export PYTHONPATH="";/App/Maya/macos/maya
您在 link 到 /usr/local/lib/python2.7/site-packages/ 的某处有一个 .pth 文件。只需检查 sys.path.
希望对您有所帮助
