我正在尝试在Anaconda Python 3.7上的Windows 10上安装OpenCV，dlib。
我已经安装了Visual studio 2015作为CMake的先决条件。当我试图在我的计算机上安装dlib时，它会给我以下错误。我也无法安装OpenCV。我试着用.whl文件安装dlib。但是，仍然没有运气。

我遇到了这个包的anaconda通道的问题。anaconda的当前版本需要Python<3.6.
我用的是pip频道而不是anaconda。通过
pip install dlib
在通过pip安装之前，请确保您使用的是当前环境pip-by-
which pip
这应该输出类似于/home/user_name/anaconda3/envs/env_name/bin/pip的内容
我尝试了很多方法来使用最新版本的Anaconda，即Python 3.7。但是，我无法做到这一点。因为.whl文件中没有一个与Python 3.7兼容，而是与Python 3.6兼容。因此，我按照链接将Python版本降级到3.6。这样一来，spyder和Python就会降级到3.6版本。完成后，我使用以下命令安装了OpenCV。
pip install opencv-python
pip install opencv-contrib-python
我使用以下命令安装了dlib。
pip install dlib-19.8.1-cp36-cp36m-win_amd64.whl
这已成功安装最新版本的dlib。
为了检查是否所有东西都安装正确，我在Anaconda提示符下使用的命令和输出如下。
(py36) C:Usersdbi227> python
Python 3.6.9 |Anaconda, Inc.| (default, Jul 30 2019, 14:00:49) [MSC v.1915 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
>>> cv2.__version__
'4.1.1'
>>> import dlib
>>> dlib.__version__
'19.8.1'
重要的是要检查您的iPython安装是否也降级到3.6。为此，在我的开始选项中，除了spyder(anaconda3(之外，我还有一个spyder选项(py36(。请确保单击spyder(py36(。因为那是安装库的地方。要检查它，您只需键入：
import cv2
import dlib
如果这些命令没有显示任何错误，则表明库已正确安装。
您需要编译它。安装Visual Studio 2019和CMake。
然后转到你的dlib文件夹，打开终端并使用命令
python3 setup.py sdist bdist_wheel
它会加载大量文本，然后在dist文件夹中会有一个轮子文件。确保您的Python 3.7.2与dlib version相对应。
最后，你所需要做的就是pip install cp37.whl
无需将Python降级到3.6.x
在Windows上实现这一点的最好方法是在conda中创建另一个环境，然后安装dlib。为什么？因为我们需要针对Windows的预构建轮子(whl(文件：
conda install -c conda-forge dlib
以及触发环境检查/依赖性检查等、包将被升级/降级/删除等。，并且很可能会对您的基础环境产生不必要的影响。因此，当我们遇到包冲突时，创建环境将使您免于头疼。conda将为您管理依赖关系。
您可以通过此处提供的.whl文件之一安装dlib：https://pypi.org/simple/dlib/
例如，如果您想为Windows 64位版本和Python 3.6安装dlib，请下载以下dlib-19.8.1-cp36-cp36m-win_amd64.whl并安装使用
pip3 install dlib-19.8.1-cp36-cp36m-win_amd64.whl
注意：请相应地验证Python版本和操作系统。
