PySide错误：无法链接QtCore

Question

I am getting the below error when trying to run my pyside program: When I try to use pip to reinstall PySide, I get the below error:

** Traceback (most recent call last):

  File "myfirstpython.py", line 3, in <module>
    from PySide.QtCore import Qt

  ImportError: dlopen(/Library/Python/2.7/site-packages/PySide/QtCore.so, 2): Symbol not found: __PyTrash_thread_deposit_object

  Referenced from: /usr/lib/libshiboken-python2.7.1.2.dylib

  Expected in: flat namespace
 in /usr/lib/libshiboken-python2.7.1.2.dylib**

When I try to check my PySide.__version__ it gives me a segmentation fault:11

I have checked several solutions available online but none seems to be working here. :

On Mac OS X, due to difficulties in compiling, don't try to use a PIP installation and try the pre-built binaries from here:

http://wiki.qt.io/PySide_Binaries_MacOSX

It has been confirmed to work for Mavericks.

You can also use brew or Macports, but I would not rely on pip: http://pythoncentral.io/install-pyside-pyqt-on-windows-mac-linux/
