我正在关注http://www.pyimagesearch.com/2016/10/24/ubuntu-16-04-how-to-install-opencv/
用于在 Ubuntu Mate 16.04 上安装 Opencv
在步骤 2 中给出的步骤#2：下载 OpenCV 源代码，我的命令没有遇到任何问题
$ wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.1.0.zip
但是当我尝试执行命令时
$ unzip opencv.zip
我收到以下错误
Archive: opencv.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of opencv.zip or
opencv.zip.zip, and cannot find opencv.zip.ZIP, period.
结果
du -hsc opencv.zip
如下面所述
0 opencv.zip
0 total
的结果
ls -l
我的主目录如下
3.1.0.zip
3.1.0.zip.1
3.1.0.zip.2

当文件夹正在下载但没有从 du 命令获取的任何内容时，链接是否有问题。有什么替代方案吗？
