Ubuntu 18.04:无法加载 SIP 模块 qgis

Ubuntu 18.04:无法加载 SIP 模块 qgis

我正在尝试在 Ubuntu 18.4 上安装 QGIS,因此我添加了这个 repo:

sudo add-apt-repository ppa:ubuntugis/ubuntugis-unstable
sudo apt-get update

最后更新了我的来源并安装了 QGis:

sudo apt update
sudo apt install qgis

但是在运行应用程序时出现这些错误:

groot@groot-Product:~$ qgis

退出应用程序后,出现以下错误:

答案1

我找到了解决问题的方法,因此我向陷入我这种情况的人回答了我的问题:

根据Stack Overflow 上的此页面

PyPI 中的 PyQt 与已安装的 Qt 不兼容

所以我使用 pip3 删除了 pyqt5:

pip3 uninstall PyQt5

并从 apt 安装 PyQt5:

sudo apt-get install python3-pyqt5

现在 Qgis 似乎可以正常工作。

答案2

在 Manjaro / ArchLinux 上为我工作。

我注意到使用 时不会出现此错误sudo qgis,但这不是一个好的解决方案,因为我想使用我的主目录,而不是 root 的目录。提示权限和路径不知为何关闭。

pip uninstall PyQt5 # defaults to pip3
sudo pacman -S python-pyqt5 python-pyqt5-sip

现在 QGIS 已成功启动 python。
