在ubuntu 16.04上安装没有Anaconda的Spyder3

(我试过按照这里的说明。我不能用Anaconda)

sudo apt-get install spyder3 

安装150MB的好东西。 然后,我做:

 pip install -U spyder 

然后我做

 spyder3 

我得到:

经过反复试验,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:您安装了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

在干净的Ubuntu 16.04.3 LTS amd64安装上测试。
