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

回答1:

The package name is actually opencv-python. So you should do:

pip install opencv-python

However, the package is only available on pypi for version 3, not for version 2. I think the misunderstanding could come from when you are actually importing the package you do:

`import cv2`

But that is actually not the package name on pypi. See the documentation on pypi for more details.

In pycharm go to :

1. File
2. Settings
3. Expand Project : [your project name]
4. Select "project Interpreter"

5. In the top right corner of the grid listing the packages, click the green plus button A popup "Available packages" will appear

   

6. If no package is available in the list in the left, click the "Manage repositories" button, add this package URL (https://pypi.python.org/simple), then restart pycharm (You may also need to update pycharm to the lastest version, there was a bug here)

7. In the search box type "opencv-python"

8. Select the "opencv-python" package in the list and click the "Install Package" button in the bottom left of the popup

9. Now go back to your code, it will no longer comply about the missing cv2
