在 Ubuntu 14.04 上为 Python 2.7 安装 PyQt5 的最佳方法

我正在尝试在我的 Ubuntu 机器上安装 PyQt5。我已经能够安装 Python 3 的软件包，但是，我的代码依赖于 pygraphviz，而 pygraphviz 对 Python 2.7 有很强的依赖性。

我浏览了 repos 并发现有一个适用于它的包：

python-pyqt5（5.3.2+dfsg-1ubuntu1）

因此我尝试以下操作：

sudo apt-get install python-pyqt5
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package python-pyqt5

因此我下载了该软件包并尝试手动安装：

sudo dpkg -i python-pyqt5_5.3.2+dfsg-1ubuntu1_amd64.deb 
Selecting previously unselected package python-pyqt5.

我发现我可能有一些过时的软件包，我尝试使用 apt-get update 进行更新，但没有结果。

我已经下载了源代码进行构建；但是，我更愿意使用包管理来控制依赖项。有没有关于如何使用 apt 解决这个问题的建议？

谢谢你的帮助！约瑟夫

我在这里找到了这个问题的答案：https://riverbankcomputing.com/pipermail/pyqt/20​​14-May/034175.html

基本上，似乎 PyQt5 的 Python 2 版本没有包含在 Ubuntu 14.04 存储库中；不过，它们似乎包含在 14.10 中。

因此，我从源代码安装了 PyQt5，但这也存在一些问题： https://stackoverflow.com/questions/32080304/issues-with-building-pyqt5-on-ubuntu-14-04

无论如何，我现在已经在我的盒子上安装了 PyQt5。

我强烈建议你安装蟒蛇并使用 conda 安装

conda install pyqt
