问题[pyqt5](ubuntu)

我Openshot在 Ubuntu 18.04 LTS 中安装了

sudo apt-get install openshot-qt

当我尝试openshot-qt在终端中打开它时，它会失败并出现错误：

Traceback (most recent call last):
  File "/usr/bin/openshot-qt", line 11, in <module>
    load_entry_point('openshot-qt==2.5.1.dev2', 'gui_scripts', 'openshot-qt')()

    from PyQt5.QtWebKitWidgets import QWebView
ModuleNotFoundError: No module named 'PyQt5.QtWebKitWidgets'

sudo apt-get install python3-pyqt5.qtwebengine我根据这个问题试过了。但是打开 openshot 会出现同样的错误，尽管 about 命令会给出：

Reading package lists... Done
Building dependency tree       
Reading state information... Done
python3-pyqt5.qtwebengine is already the newest version (5.10.1+dfsg-1ubuntu2).
0 upgraded, 0 newly installed, 0 to remove and 50 not upgraded.

有人可以提供解决方案吗？

我有很多需要 Qt4 的程序，我需要安装需要 Qt5 的程序。当我尝试安装 Qt5 时，事情开始变得狡猾，然后变得精神错乱。我请求友好的指导。您可能最容易直接查看终端输出：

我尝试的最终建议将删除我需要的一些核心内容，所以这不是一个选择。我该如何继续，好心的陌生人？

我已经使用LDOCE5 Viewer几年了。它是使用朗文当代英语词典的绝佳软件（即查看器）。在 Ubuntu 14.04 和 16.04 上，我可以使用以下命令安装此软件：

sudo apt-get install pyqt4-dev-tools qt4-designer
sudo apt-get install python3-pyqt4.phonon-dbg
sudo apt-get install python-gst0.10-dbg
sudo apt-get install python-pip
sudo pip install --upgrade Whoosh
sudo apt-get install python-lxml
cd LDOCE5Viewer
sudo make build
sudo make install

我从GitHub 上的软件源存储库中启发了这些命令。现在使用 Ubuntu 18.04 我遇到了一些错误。我从这个链接意识到我应该安装另一个版本的 LDOCE5 查看器，它基于pyqt5：

LDOCE5 的此查看器不再按预期工作。上游更新已经有一段时间了。不推荐安装此 PKGBUILD！考虑使用另一个版本的 LDOCE5 查看器（ 强烈推荐https://github.com/purboo/ldoce5viewer-pyqt5）或完全不同的字典（例如：GoldenDict）

我找不到安装新 LDOCE5 查看器的任何说明。如何在 Ubuntu 上安装这个软件？

互联网建议安装一些gstreamer软件包，但没有说明是哪个。如何确定需要哪个包？

似乎默认情况下 Ubuntu 自带，Gstreamer1.0我可以运行gst-play-1.0 FILEPATH. 任何gstreamer-0.10需要的机会吗？如何设置反向依赖？

我已安装的软件包

我正在从源代码安装 ROS 并收到有关 PyQt5 的错误。

如我们所见，错误来自subprocess.CalledProcessError: ....
我发现 '/usr/share/sip/PyQt5' 不存在。

我已阅读如何在 Ubuntu 14.10 中为 Python 3 安装 PyQt？但这无济于事。我可以pip install pyqt4而且我可以PyQt4在/usr/share/sip/.

好像是ROS在找PyQt5，/usr/share/sip/怎么安装PyQt5？
