1)不是cv2.VideoCapture()，而是cv2.videoCapture()。
Python 2.7.18rc1 (default, Apr 7 2020, 12:05:55)
[GCC 9.3.0] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> vid = cv2.videoCapture(0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'videoCapture'
>>> vid = cv2.VideoCapture(0) #like that it works fine.
>>> 尝试使用命令pip install opencv-python或pip install opencv-contrib-python安装opencv，并检查是否仍然出现"unable to import cv2“错误
