I'm running Ubuntu 13.10 (python-3.3.2+) . I've installed Qt5.2.1 (linux installer) , SIP 4.15.5 & PyQt5 both from source of the official site.

PyQt5 build :

The Qt qmake is located here

jeby6372@mercure:~$ ls /opt/Qt/5.2.1/gcc_64/bin

pixeltool             qmake           qmlscene
qcollectiongenerator  qml             qmltestrunner

My python path 

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

Qt5 libraries (shorten list for display purpose):

jeby6372@mercure:/opt/Qt/5.2.1/gcc_64/lib$ ls
cmake                              libQt5Positioning.so.5

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

I ran the following commands in the source directory extracted from the official PyQt-gpl-5.2.1.tar.gz tarball :

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

Issue:

I can only import a restricted set of modules

>>> 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'

I can import QtCore, QtNetwork ... as listed in /usr/local/python3.3/sites-packages/PyQt5 :

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

But I can't import QtWidgets, QtGui .. and so on.

It seems that the PyQt5 libraries are not all copied here.

The same problem is described in this post ... but unfortunately with no response from the RiverBanck's team :

Any idea?

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。

建造

sudo apt-get install libgl1-mesa-dev

创建或清理您的 PyQt5 编译环境并按照常规程序构建它。

选择

如果此修复无法解决您的问题，请安装 libgl1-mesa-glx 包（GLX 运行时）和 libgl1-mesa-dri（绘图加速器）（如果它们也缺失）并继续执行构建说明。

希望这有帮助。
