我需要将 numpy 数组转换为 QtGui.QImage。但我不知道该怎么做。我找到了这个： http: //kogs-www.informatik.uni-hamburg.de/~meine/software/qimage2ndarray/但是当我尝试安装它时出现错误：
michael@michael-laptop-ubuntu:~/rubyWorkSpace/pymcs$ easy_install
error: No urls, filenames, or requirements specified (see --help)

当我尝试修复像 ekhumoro 说的错误时：

我不明白这个错误，因为显然 import numpy 有效......
如果有人知道将 numpy 数组转换为 QImage 的另一种方法，那就太好了。谢谢。
