无法在 Centos 8 上安装 libQtGui.so.4

无法在 Centos 8 上安装 libQtGui.so.4

对于计算机视觉（机器学习）测试，我需要安装OIDv4_工具包 我正在按照链接中的说明进行操作。在 centos 8 上我使用过： conda install --filerequirements.txt

但是，当尝试运行时： python3 main.py -h

我收到此错误：

liran@localhost OIDv4_ToolKit]$ python3 main.py -h
Traceback (most recent call last):
  File "main.py", line 20, in <module>
    from modules.downloader import *
  File "/home/liran/dev/ComputerVisionRT/OIDv4_ToolKit/modules/downloader.py", line 2, in <module>
    import cv2
  File "/home/liran/anaconda3/lib/python3.7/site-packages/cv2/__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: libQtGui.so.4: cannot open shared object file: No such file or directory

在此之前，我遇到了同样的错误，但是使用 libjpeg.so.8 ，但我设法通过在主机上找到它来解决它：

sudo find / -name  libjpeg.so.8

然后将找到的目录添加到 LD_LIBRARY_PATH 环境变量中

export LD_LIBRARY_PATH=/path/to/file/:$LD_LIBRARY_PATH

我找到了一个应该包含缺失模块的 RPM这里 但安装 rpm 后：

[liran@localhost OIDv4_ToolKit]$ sudo dnf install /path/to/rpm/qt-x11-4.8.7-9.el7_9.x86_64.rpm

我得到：

有任何想法吗？

我安装了https://github.com/EscVM/OIDv4_ToolKit按照干净的 centos8 docker 镜像中的说明进行操作。

我需要 python-devel、gcc、make、cmake 以及在某个时候建议的“开发工具”包。不是QT。

然后我就可以python3 main.py -h成功运行命令了。

您很可能在系统上安装了不适当的软件包（可能是通过配置错误的软件包源或手动安装 RPM），现在您的系统已损坏，而不是 oidv4 工具包出现任何问题。

您不需要手动安装任何 RPM dnf install package-name。您不需要添加包源。

我建议您重新开始全新安装。
