<div class =“post-text”itemprop =“text”> <P> 试试这个： </p> <pre> <code> sudo ldconfig sudo nano /etc/ld.so.conf.d/opencv.conf </code> </pre> <P> 并在中添加以下行 <code> opencv.conf </code> 不在命令窗口中 </p> <pre> <code> /usr/local/lib </code> </pre> <P> 然后： </p> <pre> <code> sudo ldconfig sudo nano /etc/bash.bashrc </code> </pre> <P> 并添加这两行 <code> bash.bashrc </code> 不在命令窗口中 </p> <pre> <code> PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig export PKG_CONFIG_PATH </code> </pre> <P> 最后重启你的Pi <code> sudo reboot now </code> </p> <P> 并尝试 <code> import cv2 </code> </p> </DIV>

<div class =“post-text”itemprop =“text”> <P> 上述答案都不适合我。我发疯了，直到我在下面找到这个解决方案！ </p> <P> 简单地运行： </p> <pre> <code> sudo apt install python-opencv </code> </pre> </DIV>

<div class =“post-text”itemprop =“text”> <P> 的<strong> 如果您正在从划痕中建立，请通过此操作 </强> </p> <P> 你得到 <code> No module named cv2.cv </code> 。 儿子，你做的一切都是正确的，因为你的 <code> sudo make install </code> 没有错误。 </p> <P>

<div class =“post-text”itemprop =“text”> <P> 我有同样的问题，只是无法弄清楚opencv2和opencv3分别安装到/ opt / opencv和opencv3。原来，在我的主目录中的血腥anaconda安装opencv是第一个路径和损坏opencv。删除它并开始使用/etc/ld.so.conf.d/opencv.conf中定义的/ opt / opencv3 / lib。先完成工作。你有安装anaconda吗？可能是问题。 </p> </DIV>
