我试图通过Anaconda为Python安装OpenCV，但我似乎无法解决这个问题。
我试着
conda install opencv
conda install cv2
我也试着搜索
conda search cv
没有雪茄。我无意中看到这个列出了opencv作为一个包含包:
http://docs.continuum.io/anaconda/pkgs.html
在运行conda info后，我注意到我的版本是3.4.1，但我似乎在网上找不到任何关于这个版本的信息。我对此很困惑。
我是不是遗漏了一些很明显的东西?如果opencv可用于Anaconda的以前版本，那么为什么它不能用于新版本呢?为什么这个链接只显示版本1.9.2的文档?

和其他人一样，我在OS X 10.11上使用Python 3.5.1/Anaconda 2.4.0时遇到了问题。
但我在这里找到了一个兼容的软件包:
https://anaconda.org/menpo/opencv3
它可以像这样通过命令行安装:
conda install -c https://conda.anaconda.org/menpo opencv3
效果很好。这是我第一次在3.x上使用OpenCV !

你链接的页面好像不再包含opencv了。(有趣的是，我确实记得它在之前也被包括在内。)
在任何情况下，安装OpenCV到Anaconda，虽然无法通过conda，是相当微不足道的。你只需要下载一个文件。
Download OpenCV from https://opencv.org/releases/ and extract From the extracted folder, copy the file from the extracted directory: opencv/build/python/2.7/(either x86 or x64, depending on your Anaconda version)/cv2.pyd to your Anaconda site-packages directory, e.g., C:\Anaconda\Lib\site-packages To get FFmpeg within opencv to work, you'll have to add the directory that FFmpeg is located in to the path (e.g., opencv/sources/3rdparty/ffmpeg). Then you'll have to find the DLL file in that folder (e.g., opencv_ffmpeg_64.dll) and copy or rename it to a filename that includes the opencv version you are installing, (e.g., opencv_ffmpeg249_64) for 2.4.9.
现在在Python提示符下，你应该可以输入“import cv2”…要验证它是否有效，输入“print cv2”。__version__”，它应该打印出你下载的OpenCV版本。
虽然不是通过Conda，这是Ubuntu特有的，安装OpenCV的所有贡献模块，如SIFT和SURF，最简单的方法是使用:
PIP安装opencv-contrib-python
它支持Python2.7+和Python 3.4+
如果你选择不内置contribs，你可以这样做:
PIP安装opencv-python
在运行这些命令之前，你需要安装以下依赖项:
Sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

2019年5月，MacOS的答案如下:
conda update freetype
conda install opencv -c conda-forge
这会更新libfreetype.6。dylib到24.0.0兼容性并安装OpenCV 4.1.0。
下面从conda-forge安装opencv(注意:在Windows上尝试过)
conda config --add channels conda-forge
conda install opencv
我有步骤在回购，将帮助您正确安装OpenCV。

对于要求和先决条件，请遵循以下说明:
你需要有WINDOWS操作系统来开始这个项目。
Windows 7到10
请仔细执行以下步骤
Install Anaconda2 32/64 python 2 or Install Anaconda3 32/64 python 3 It Depends on System Information Along the way you must check all the options ignore the red text Then wait till installation completed ... Open CMD admin when finish installed Make sure that the anaconda-python is configured in CMD admin Type: python This will come out: C:\WINDOWS\system32>python Python 3.6.3 |Anaconda custom (64-bit)| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. Next is to install packages: Numpy OpenCV PyMySQL or pymysql Install and Import OpenCV conda install -c conda-forge opencv = (version optional) (click yes if there's updates) Install and Import Numpy pip install numpy (click yes if there's updates) Install and Import PyMySQL/pymysql pip install PyMySQL or pymysql When all the package is completely installed, then you must Reboot it. go to CMD admin again type "python" import cv2 (cv2 is OpenCV) import Numpy or numpy import pymysql import os from PIL from Image if all of then is ok.. your ready to run the code!! After you finish all the steps, you can now test the code in SPYDER python that I use
