为什么下面的路径没有python3.5？我已经使用自制软件为 Python3 安装了 OpenCV3。你可以在这里找到完整的自制软件要点。
根据本教程，我应该按照步骤操作（太糟糕了，我不知道教程所用的语言）：http: //qiita.com/HirofumiYashima/items/eb697b1e359586b538e6
ls /usr/local/Cellar/opencv3/3.1.0_3/lib/python2.7/site-packages/cv2.so
我希望有以下内容：
ls /usr/local/Cellar/opencv3/3.1.0_3/lib/python3.5/site-packages/cv2.cpython-35m-darwin.so
任何见解都会非常有用！

更新：我安装了 opencv3 并用 python3 再次安装了它。但是，正如您在已安装的库中看到的仅 Python2.7 所示：
bash-4.3$ brew install opencv3 --with-python3

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.
opencv3 and opencv install many of the same files.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
LDFLAGS: -L/usr/local/opt/opencv3/lib
CPPFLAGS: -I/usr/local/opt/opencv3/include
If you need Python to find bindings for this keg-only formula, run:
echo /usr/local/opt/opencv3/lib/python2.7/site-packages >> /usr/local/lib/python2.7/site-packages/opencv3.pth
