我应该如何解决这个问题？

安装 opencv 使用:

conda install -c conda-forge opencv=3.2.0 

甚至尝试过:

$ conda install -c anaconda openblas=0.2.19

Package plan for installation in environment /Users/mona/anaconda:

The following NEW packages will be INSTALLED:

    libgfortran: 3.0.0-1       anaconda   
    openblas:    0.2.19-1      anaconda   

The following packages will be SUPERSEDED by a higher-priority channel:

    conda:       4.3.22-py36_0 conda-forge --> 4.3.22-py36_0 anaconda
    conda-env:   2.6.0-0       conda-forge --> 2.6.0-0       anaconda

但是还是一样的错误。这是我的 conda list https://pastebin.com/gP0F0Qnz 的输出我应该如何修复它才能import cv2？

您似乎没有安装 openblas，它是 opencv 的必需模块，但不知何故未包含在其依赖项中，因此您必须手动安装它，您可以使用 conda list|grep openblas 确认这一点

如果您没有 openblas，请使用以下命令安装它:conda install -c conda-forge openblas=0.2.19

希望对你有帮助
