ModuleNotFoundError：Python 中没有名为“cv2”的模块 - Windows

Question

$ python --version
Python 3.9.13

我努力了：

pip3 install opencv-python

也试过

pip install opencv-python 

并且都得到相同的错误

ModuleNotFoundError: No module named 'cv2'

我已经尝试卸载并重新安装，以防它损坏并且没有任何运气。
以下是错误。

我刚开始这个项目，所以代码不多，只是试图导入库 cv2 库

import cv2


cv2.waitKey(0)

print("Code Completed")

Answer 1

这也发生在我身上，尝试运行

pip install opencv-python

在虚拟环境中。 创建一个运行

python3 -m venv tutorial-env

然后激活虚拟环境。

tutorial-env\Scripts\activate.bat

窗户。

完成此操作后，运行 pip install 然后它应该可以工作。
