Pycharm/Python OpenCV和CV2安装错误

问题描述

我一直在尝试按照以下建议从Pycharm和终端安装OpenCV和cv2:

I've been trying to install both OpenCV and cv2 from both Pycharm and from the terminal as suggested using:

pip install --user opencv
pip install --user cv2

但是我遇到了以下错误:

but I'm getting the following error for them:

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

和

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

如何解决这些问题并正确安装软件包?我正在使用python 3.4.

How can I fix these and install the packages properly? I'm using python 3.4.

推荐答案

由于opencv和cv2不是python软件包名称，因此您会收到这些错误.

You are getting those errors because opencv and cv2 are not the python package names.

这些都包含在opencv-python软件包中，可从pip安装.

These are both included as part of the opencv-python package available to install from pip.

如果您使用的是python 2，则可以使用pip进行安装:

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

 pip install opencv-python

或者对python 3使用等效项:

Or use the equivilent for python 3:

pip3 install opencv-python

运行适当的pip命令后，您的软件包应可从python使用.

After running the appropriate pip command your package should be available to use from python.
