安装 dlib 时出错，尽管已经安装但在 venv 目录中找不到 Cmake

Question

我已经通过 pip install Cmake 安装了 Cmake，以及 Wheel 和 numpy。

尝试使用 pip install dlib 安装 dlib 时出现错误：

PS G:\WORK\EncroFace>

查看我的 venv 目录，我可以看到 cmake 文件已安装，我是否缺少另一个先决条件？网上的所有内容都说这应该有效。

我一直在 VScode 中工作，python 版本 3.12.2

我尝试直接从他们的网站安装 Cmake 并卸载并重新安装 python 模块。

当我点列表时它也会显示：

PS G:\WORK\EncroFace> pip list
Package         Version
--------------- --------
build           1.2.1   
cmake           3.29.0.1
colorama        0.4.6   
numpy           1.26.4  
packaging       24.0    
pip             24.0    
pyproject_hooks 1.0.0   
setuptools      69.2.0  
wheel           0.43.0  
PS G:\WORK\EncroFace> 

任何帮助将不胜感激。

首先使用 pip install cmake 在 venv 中安装 cmake

然后尝试使用二进制文件安装 dilb https://github.com/z-mahmud22/Dlib_Windows_Python3.x

找到适合您的Python版本的文件并按照安装指南进行操作 记得在执行命令之前将 whl 文件粘贴到项目文件夹中
