python - 操作系统: Maya Python Qt conflict with system libraries

Question

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:

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 的应用程序链接到 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)。

我猜这是一个特定于 OSX 的问题。如何强制应用程序运行自己的Qt库？

编辑: 我删除了随brew 安装的Qt、PySide 和Shiboken 软件包，以检查它们是否被Maya 拾取。如果没有设置 PYTHONPATH，PySide 仍然会从系统目录中获取:

import PySide
PySide.__file__
# Result: /usr/local/lib/python2.7/site-packages/PySide/__init__.pyc #

我今天也遇到了同样的问题，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

您现在应该看到它错误地列出了 /usr/local/lib/python2.7/site-packages/

几个原因:

• 您正在配置文件(.bashrc、.profile、.zshrc ...)中设置 PYTHONPATH 并从命令行运行 Maya。在这种情况下，您有两个选择。从您的配置文件中删除 PYTHONPATH 或添加一个别名来在运行 Maya 之前为您执行此操作，

  类似的事情: alias maya=export PYTHONPATH="";/App/Maya/macos/maya

• 您有一个 .pth 文件链接到 /usr/local/lib/python2.7/site-packages/。只需检查 sys.path 返回的文件夹列表即可。
