Question

我正在使用Python 2和Python 3.我正在努力使pylab变体ipython在Python 3上运行（因为它在Python 2上运行良好）。

无法安装PyQt4后，我尝试使用以下PySide命令安装pip install：

sudo pip -vvv install --upgrade pyside

花了一段时间。我的电脑也很热。但达到100％后，安装失败并显示以下错误消息：

        Traceback (most recent call last):
          File "<string>", line 1, in <module>
          File "/tmp/pip-build-o8v5e0ej/pyside/setup.py", line 1001, in <module>

总而言之，pylab对我没有帮助。正在运行ipython --pylab加注

ImportError: libpyside.cpython-34m.so.1.2: cannot open shared object file: No such file or directory

这是行

的结果

from PySide import QtCore, QtGui, __version__, __version_info__

我做错了吗？

我的系统信息：

Python 3.4.0
Ubuntu 14.04.3 LTS（可信赖）
架构：64位
内核版本：3.16.0-40-generic

我不完全确定这是对我的问题的正确答案，因为它并没有真正解决pip的问题，但我已经成功解决了我的机器上的pylab问题，并且这就是我所做的：

我已清除（通过aptitude） python3-pyqt4和python3-pyqt5
我已卸载（通过pip）python pyside
我已安装（通过aptitude）python3-pyside

现在ipython --pylab有效（使用Python 3.4.0）。

pip安装PySide失败了
