Pycharm，Python 安裝OpenCV and CV2 時，報錯，教你如何正確安裝。

Collecting cv2
  Could not find a version that satisfies the requirement cv2 (from versions: )
No matching distribution found for cv2

 

初學Python，在安裝cv2框架的時候，報以上錯誤，試了很多次  pip install cv2  依然無效，后來查閱了好多資料，總結下面的方法，安裝了opencv后，里面包含了cv2框架。

 

If you are using python 2 you can install with pip:

pip install opencv-python

Or use the equivilent for python 3:

pip3 install opencv-python
