我想为一个即将启动的项目安装face_recognition。但是，face_recognition依赖于dlib，我不知道如何安装。
我进入pip install dlib，然而，一个错误被抛出，因为它说我需要安装CMake。下面是错误:
Using cached dlib-19.24.0.tar.gz (3.2 MB)
Preparing metadata (setup.py) ... done
Installing collected packages: dlib
DEPRECATION: dlib is being installed using the legacy 'setup.py install' method, because it does not have a 'pyproject.toml' and the 'wheel' package is not installed. pip 23.1 will enforce this behaviour change. A possible replacement is to enable the '--use-pep517' option. Discussion can be found at https://github.com/pypa/pip/issues/8559

然而，当我试图再次安装dlib时，即使我成功安装了CMake，我也得到了同样的错误。
我现在如何安装dlib ?作为参考，我使用的是Windows 10或11系统，Python 3.11 64位。
更新/安装Visual c++
也许尝试安装/更新Visual c++。因为这是CMake运行所必需的。你可以从这里安装，https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=15#
车轮文件安装
运行:
pip install https://pypi.python.org/packages/da/06/bd3e241c4eb0a662914b3b4875fc52dd176a9db0d4a2c915ac2ad8800e9e/dlib-19.7.0-cp36-cp36m-win_amd64.whl#md5=b7330a5b2d46420343fbed5df69e6a3f
从Internet安装
- Install CMake from https://cmake.org/download/
- 运行这个,
set PATH="%PATH%;C:Program FilesCMakebin添加CMake到你的路径。您也可以通过编辑环境变量手动执行此操作。3)下载以下文件:https://pypi.org/project/dlib/文件。 - 在解压安装文件的指定文件夹中运行以下命令:
python setup.py install。
