Ubuntu 18.04：無法載入 SIP 模組 qgis

我正在嘗試在 Ubuntu 18.4 上安裝 QGIS 所以我添加了這個存儲庫：

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

最後更新了我的原始碼並安裝了 QGis：

sudo apt update
sudo apt install qgis

但在運行應用程式時我收到以下錯誤：

groot@groot-Product:~$ qgis

退出應用程式後，我收到以下錯誤：

答案1

我找到了解決問題的方法，所以我向陷入我的情況的人回答了我的問題：

根據Stack Overflow 上的此頁面:

PyPI中的PyQt與已安裝的Qt不相容

所以我使用 pip3 刪除了 pyqt5：

pip3 uninstall PyQt5

並從 apt 安裝 PyQt5：

sudo apt-get install python3-pyqt5

現在 Qgis 似乎可以正常工作。

答案2

在 Manjaro / ArchLinux 上為我工作。

我注意到我沒有收到此錯誤sudo qgis，但這不是一個好的解決方案，因為我想使用我的主目錄，而不是根目錄。提示權限和路徑以某種方式關閉。

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

現在QGIS已經成功啟動python了。
