Fatal error while compiling PyQt5: Python.h does not exist

Question

I'm trying to install PyQt5 on my Ubuntu 12.04 box. So after downloading it from here I untarred it, ran python configure.py and make . Make however, results in the following:

cd qpy/ && ( test -f Makefile || /opt/qt5/bin/qmake /home/kram/Downloads/PyQt-gpl-5.0/qpy/qpy.pro -o Makefile ) && make -f Makefile 
make[1]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy' is entered
cd QtCore/ && ( test -f Makefile || /opt/qt5/bin/qmake /home/kram/Downloads/PyQt-gpl-5.0/qpy/QtCore/QtCore.pro -o Makefile ) && make -f Makefile 
make[2]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy/QtCore' is entered
g++ -c -pipe -fno-strict-aliasing -O2 -Wall -W -fPIC -D_REENTRANT -DQT_NO_DEBUG -DQT_CORE_LIB -I/opt/qt5/mkspecs/linux-g++ -I. -I. -I../../QtCore -I/usr/local/include/python2.7 -I/opt/qt5/include -I/opt/qt5/include/QtCore -I. -o qpycore_chimera.o qpycore_chimera.cpp
qpycore_chimera.cpp:21:20: fatal error: Python.h: File or folder does not exist
compilation terminated.

make[1]: Map '/home/kram/Downloads/PyQt-gpl-5.0/qpy' is left
make: *** [sub-qpy-make_first-ordered] Error 2

(I translated some parts of the error message from Dutch to English, so some words may be a bit off from the normal wording..)

Does anybody what the problem is here? Where could the relevant Python.h file be?

Answer 1

The problem is that the include path for all python headers in every Makefile will be pointing to /usr/local/include/python2.7 , which should have been /usr/include/python2.7

There are 2 possible solutions for this. Either you can change all the occurrence of this in every Makefile or else you can create a symlink to that location

sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7

Now you can run make

Answer 2

sudo apt-get install python-dev

您缺少python头文件。

Answer 3

The problem you're having is that PyQt assumes you're not using your distro's managed python, and instead defaults to looking for sip in /usr/local/include/python2.7 .

Luckily, configure.py provides options to override the python and sip include locations:

python configure.py --sip-incdir /usr/include/python2.7 py_inc_dir=/usr/include/python2.7

This solution should preferred to symlinking /usr/include/python2.7 into /usr/local/include/python2.7 as that will enable manually installed software to pollute (or corrupt packages installed to) distro-managed paths.

最好在QTCreator和Anjuta IDE中将现有的头文件添加到项目目录中。
