Python Camelot ImportError：导入 cv2 时 DLL 加载失败：找不到指定的模块

Question

我已经安装了camelot，它已安装opencv作为其对我的Windows 10（Windows 10 Pro N）的依赖项。当尝试运行我的文件以使用camelot时，它给出了错误： “导入错误：导入 cv2 时 DLL 加载失败：找不到指定的模块。”

我已经应用了本页提到的第一个和第二个解决方案导入cv2时出现DLL加载失败错误 但是出现同样的错误

我的系统上安装的python版本是：3.9.5。而且我还没有通过 Annaconda 安装 python。

错误的完整回溯是：

Traceback (most recent call last):
File "D:\340bpython\newfile.py", line 1, in <module>    import camelot
File "D:\python\lib\site-packages\camelot\__init__.py", line 6, in <module> from .io import read_pdf

ImportError: DLL load failed while importing cv2: The specified module

Answer 1

尝试同时安装 cv2：

py -m pip install --user "camelot-py[base]" opencv-python
