Question

我正试图在我的树莓派上运行picam。不幸的是，我没有解决以下导入错误：

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-1-ae50f21e1c18> in <module>()

      2 import time

/usr/local/lib/python2.7/dist-packages/picam/__init__.py in <module>()

----> 3 from _picam import *
      4 import StringIO
      5 from PIL import Image

ImportError: /usr/local/lib/python2.7/dist-packages/picam/_picam.so: cannot open shared object file: No such file or directory

我一直在寻找这个地方（例如：cannot open shared object file: No such file or directory），但到目前为止还没有成功。由于一大堆缺少的库（mmal.h，vcos.h等），重新编译也无法正常工作。

更新

pi@raspberrypi ~ $ ls -l /usr/local/lib/python2.7/dist-packages/picam
total 48

UPDATE2：

    not a dynamic executable

通过PIP安装时，软件包应包含共享对象文件。它并不理想，但您可以从github自行下载并将其放在所需的文件夹中。或者，您可以尝试从PIP重新安装。 https://github.com/ashtons/picam/tree/master/picam

ls -l /usr/local/lib/python2.7/dist-packages/picam的输出在你的pi上是什么样的？
