当我尝试在iTerm上安装pyside时，完成后我会收到
/bin/sh: line 1: 19051 Segmentation fault: 11 /usr/local/Cellar/shiboken/1.1.2/bin/shiboken --generator-set=shiboken --enable-parent-ctor-heuristic --enable-pyside-extensions --enable-return-value-heuristic --use-isnull-as-nb_nonzero /tmp/pyside-s45Y/pyside-qt4.8+1.1.2/macbuild/PySide/pyside_global.h --include-paths=/tmp/pyside-s45Y/pyside-qt4.8+1.1.2/PySide:/usr/local/Cellar/qt/4.8.5/Frameworks --typesystem-paths=/tmp/pyside-s45Y/pyside-qt4.8+1.1.2/PySide:/tmp/pyside-s45Y/pyside-qt4.8+1.1.2/PySide/QtCore --output-directory=/tmp/pyside-s45Y/pyside-qt4.8+1.1.2/macbuild/PySide/QtCore --license-file=/tmp/pyside-s45Y/pyside-qt4.8+1.1.2/PySide/QtCore/../licensecomment.txt /tmp/pyside-s45Y/pyside-qt4.8+1.1.2/macbuild/PySide/QtCore/typesystem_core.xml --api-version=4.8 --drop-type-entries=""
