Question

我有两个Raspberry Pi 3。当我做的时候

(tfenv)pi@raspberrypi:~ $ pip install opencv-python==

在第一个Raspberry Pi上，我得到了：

 Collecting opencv-python
Could not find a version that satisfies the requirement opencv-python== 
(from versions: 3.1.0.0, 3.1.0.1, 3.1.0.2, 3.1 .0.3, 3.1.0.5, 3.2.0.6, 3.2.0.7) No matching distribution found for opencv-python==

在第二个Raspberry Pi上，我得到了：

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

我怀疑是因为每个版本都安装了不同版本的Raspbian。 Raspberry Pi 2已安装Strech，Raspberry Pi 2已Jessie 我是对还是别的错了？

更新

我使用pip install --verbose opencv-python==，结果如下：

Rasberry Pi，点不起作用

正确运行pp的Raspberry Pi

相同命令在不同设备上输出不同的值
