安装PyQt5并sip失败

我用这样的python 2.7创建了一个虚拟环境:virtualenv py_env

然后我想安装SIP(sip-4.19.1)和PyQt5(PyQt-gpl-5.5.1),所以我下载了两个(riverbankcomputing)并试图像这样安装它们:

cd py_env
cd sip-4.19.1/
python configure --incdir=../include/python2.7/
make
sudo make install

这很好用,python确认现在可以导入sip:

>>> import sip
>>> sip
<module 'sip' from 
'/home/robin/Develop/py_todo_env/local/lib/python2.7/site-
packages/sip.so'>

接下来,我这样做是为了安装PyQt5:

cd ../PyQt-gpl-5.5.1/
python configure --sip-incdir=../include/sip/
make
ERROR!!!

运行时出现错误:

我尝试过不同版本的sip和pyqt5,有些工作,例如pyqt 5.10,但是我没有QtWebEngineWidgets模块可以导入,所以那里也有问题..为什么这么难做到这一点?
