1. pip install cv2刚开始因担心下载cv2时,可能因为网络原因,导致时间超出,所以使用pip install --default-timeout=1000 cv2,但是发现出现如下错误:PS F:\py代码> pip install --default-timeout=1000 cv2ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)ERROR: No...
1. pip install cv2

刚开始因下载cv2时,可能因为网络原因,导致时间超出,所以使用pip install --default-timeout=1000 cv2,但是发现出现如下错误:

PS F:\py代码> pip install --default-timeout=1000 cv2
ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)
ERROR: No matching distribution found for cv2

然后我又试了下pip install cv2,发现还是出现如下错误:

PS F:\py代码> pip install cv2
ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)
ERROR: No matching distribution found for cv2
2. pip install opencv-python

然后发现opencv中的cv2在opencv-python包里面,所以可以用pip install opencv-python,但是可能因为网络原因,导致时间超出,可能会出现如下错误:

PS F:\py代码> pip install opencv-python

2. pip install --default-timeout=1000 opencv-python

使用pip install --default-timeout=1000 opencv-python,可能会出现错误,错误界面如下:

如果不能正确安装可以多安装几次,即可,正确安装界面如下:
