在python 3.5.2 windows 10上安装picamera时出错

Question

我试着用pip 9在windows 10上安装python3.5上的picamera。

另外，我在网上查看并知道我需要安装pyyaml，我确实安装了。这真的很奇怪，有人认为pip需要和setup.py位于同一个位置？更让人困惑的是。总之，下面是我所做的，希望能有所帮助。

执行命令：

pip install --user picamera

命令输出：

发生错误：

FileNotFoundError: [Errno 2] No such file or directory: '/proc/cpuinfo'

试着用吡喃安装它，但还是没有运气。

Answer 1

FileNotFoundError: Errno 2没有这样的文件或目录：'/proc/cpuinfo‘

因为该文件只存在于linux或类unix系统中，而不是在Windows系统或mac中，这就是为什么您无法成功的原因。

Answer 2

我在和Kivy和python一起工作的时候遇到了同样的问题。

错误地说“没有找到名为picamera的模块”

帮助我度过难关的解决方案：

pip install opencv-python

是的！它帮了我，也许能为你工作。

编辑:我在Python3.7上尝试过这个(OS : Windows 10)

Answer 3

虽然它很古老，但对于遇到同样问题的人来说可能是有用的。步骤。

1. 打开终端(如果您有一个虚拟env，请激活它)
2. 类型"set READTHEDOCS=True“
3. pip安装picamera或4.pip安装picameraarray
