安装 PyQt 时出错

Question

I am now trying to run PyQt. I am still getting the following error when I do the following:

root@localhost:/home/abhowmik/app/imgSeek-0.8.6# cd Py*
root@localhost:/home/abhowmik/app/imgSeek-0.8.6/PyQt-x11-gpl-4.8.4# python configure.py --verbose

Can someone help me how to fix the problem?

Answer 1

Problem is that configure.py is trying to use qmake from qt3. Try this:

python configure.py --qmake /usr/bin/qmake-qt4

(You might have qmake-qt4 somwhere else than /usr/bin so check that first )

Answer 2

Try this, http://samos-it.com/install-pyqt-in-a-virtualenv-with-pip/

Install the development headers (Ubuntu 12.04):

sudo apt-get install libqt4-dev

Then try again

This is a slightly modified answer of @Flyte which worked for me on CentOS 6.5

• activate your virtualenv(optional in case you want to install in virtualenv)
• wget http://sourceforge.net/projects/pyqt/files/sip/sip-4.15.4/sip-4.15.4.zip(your corresponding version)
• unzip sip-4.15.4.zip
• cd sip-4.15.4
• python configure.py --incdir=/opt/include/python2.7(path where python is located)
• make and make install this completes the installation of SIP one of the prerequsite -Then to install PyQt4
• wget http://sourceforge.net/projects/pyqt/files/PyQt4/PyQt-4.10.3/PyQt-x11-gpl-4.10.3.tar.gz
• tar zxvf PyQt-x11-gpl-4.10.3.tar.gz
• cd PyQt-x11-gpl-4.10.3
• python2.7 configure.py -k --qmake /usr/bin/qmake-qt4
• make and finally make install

this worked for me hope it helps you also. also make sure you have proper version of qt installed usually need to use qt version>4.7

试试 PIP，python 包管理器：

pip3 install pyqt5
