安装 150MB 的好东西。然后，我这样做：
pip install -U spyder
然后我就这么做了

经过反复尝试，我可以提出以下建议：
sudo apt-get install python3-pip python3-pyqt4 \
python3-pyqt5 python3-pyqt5.qtsvg python3-pyqt5.qtwebkit
sudo pip3 install -U spyder
结果：您已安装 Spyder3，并且其关于Spyder窗口包含
Spyder 3.2.4
...
Linux 上的 Python 3.5.2 64 位、Qt 5.5.1、PyQt5 5.5.1
