OpenCV in archlinux/manjaro

Question

我在我的Manjaro分区上安装了Numpy 1.10.4-1和OpenCV 2.4.12.2-2。当我试图将cv2导入python2.7脚本时，我会得到结果错误。

>>> import cv2
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /usr/lib/python2.7/site-packages/cv2.so)
>>>

我已经在网上搜索了一个答案，但我永远无法得到一个明确的解决办法。有什么想法吗？

Answer 1

为python2.7安装pip2

pacman -S python2-pip

然后使用pip2安装opencv-python

sudo pip2 install opencv-python

现在，您应该能够导入cv2，而不会出现问题。

Python 2.7.15 (default, Jun 27 2018, 13:05:28) 
[GCC 8.1.1 20180531] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>>
