启动时出现此错误qtconsole。

我已经安装了：

sudo apt-get install libzmq-dev
sudo pip install pyzmq
sudo pip install pygments
sudo apt-get install libqt4-core libqt4-gui libqt4-dev

有人能帮我弄清楚发生了什么吗？我对这个系统还很陌生，可能错过了一些非常基本的东西……谢谢

答案1

您需要额外安装：

sudo pip install qtconsole

或通过 apt

sudo apt-get install ipython-qtconsole   # for Python2

为什么？

apt-file search qtconsoleapp

或阅读这。

答案2

安装

pip install pyqt5 qtconsole

跑步

jupyter qtconsole

细节

该命令ipython qtconsole已被弃用，取而代之的是jupyter qtconsole。出于某种原因，pip install qtconsole不会安装依赖项pyqt5。我认为这与能够qtconsole使用不同的库进行显示有关，包括pyside？

这是在 Ubuntu 17.10 和 Python 3 上测试的。
