PyQt5 - 错误导入QtWidgets QtGui

Question

我正在运行Ubuntu 13.10(python-3.3.2 +).我从官方网站的源代码安装了Qt5.2.1(linux安装程序),SIP 4.15.5和PyQt5.

PyQt5构建:

Qt qmake位于此处

jeby6372@mercure:~$ ls /opt/Qt/5.2.1/gcc_64/bin
assistant             qdbus           qml1plugindump    qmlviewer

moc                   qhelpgenerator  qmlprofiler       xmlpatternsvalidator
pixeltool             qmake           qmlscene
qcollectiongenerator  qml             qmltestrunner

我的python路径

jeby6372@mercure:~$ echo $PYTHONPATH
:/usr/lib/python3.3/site-packages

Qt5库(缩短列表用于显示目的):

jeby6372@mercure:/opt/Qt/5.2.1/gcc_64/lib$ ls

libQt5Platfor
libQt5PlatformSupport.prl          libQt5Xml.so.5.2
libQt5Positioning.so

我在从官方PyQt-gpl-5.2.1.tar.gz tarball中提取的源目录中运行以下命令:

python3 configure.py --qmake /opt/Qt/5.2.1/gcc_64/bin/qmake # My PyQt5 location
sudo make
sudo make install

问题:

我只能导入一组受限制的模块

>>> from PyQt5.QtCore import *
>>> from PyQt5.QtNetwork import *
>>> from PyQt5.QtXmlPatterns import *
>>> from PyQt5.Qt import *
>>> from PyQt5.QtGui import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'PyQt5.QtGui'
>>> from PyQt5.QtWidgets import *
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named 'PyQt5.QtWidgets'

我可以导入QtCore,QtNetwork ...,如/usr/local/python3.3/sites-packages/PyQt5中所列:

jeby6372@mercure:/usr/lib/python3.3/site-packages/PyQt5$ ls
__init__.py  QtCore.so  QtDBus.so  QtNetwork.so  Qt.so  QtXmlPatterns.so  uic

但是我无法导入QtWidgets,QtGui ..等等.

似乎PyQt5库并非全部复制到这里.

这篇文章描述了同样的问题......但遗憾的是RiverBanck团队没有回复:

任何的想法？

Answer 1

缺少包裹

按照mata的建议安装缺少的libgl1-mesa-dev依赖项.它是OpenGL API的免费实现.

建立

sudo apt-get install libgl1-mesa-dev

创建或清理PyQt5编译环境并根据常规过程构建它.

替代

如果此修复程序无法解决您的问题,请安装libgl1-mesa-glx软件包(GLX运行时)和libgl1-mesa-dri(绘图加速器)(如果它们也缺失)并继续构建指令.

希望这有帮助.
