Building wheel for dlib (setup.py) ... error

如果在安装`dlib`时出现了类似以下的错误：

Building wheel for dlib (setup.py) ... error

这通常意味着你需要安装一些依赖项来成功编译`dlib`的安装包。具体来说，`dlib`需要C++编译器和一些其他的C++库来构建其安装包。

对于Linux用户，你可以使用以下命令来安装`dlib`的依赖项：

sudo apt-get install build-essential cmake libopenblas-dev liblapack-dev libx11-dev libgtk-3-dev

对于Windows用户，你需要先安装C++编译器，例如Visual Studio，然后使用以下命令安装`dlib`的依赖项：

pip install numpy scipy matplotlib scikit-image scikit-learn ipython

一旦你安装了这些依赖项，你应该可以成功安装`dlib`了。如果你仍然遇到问题，请尝试在安装`dlib`之前更新`pip`和`setuptools`：

pip install -U pip setuptools

然后再次尝试安装`dlib`：

pip install dlib

ERROR: Failed building wheel for dlib Running setup.py clean for dlib Failed to build dlib ERROR: Could not build wheels for dlib, which is required to install pyproject.toml-based projects

这个错误提示是因为缺少CMake，它是dlib的构建工具之一。你需要先安装CMake，然后再重新安装dlib。你可以使用以下命令安装CMake：

pip install cmake

然后再重新安装dlib：

pip install dlib

如果你在Windows操作系统下安装dlib，还需要安装Visual Studio并安装C++工具。如果你已经安装了Visual Studio，可以使用以下命令安装C++工具：

"C:\Program Files (x86)\Microsoft Visual Studio\Installer\vs_installer.exe" --installPath C:\BuildTools --add Microsoft.VisualStudio.Workload.VCTools --passive --norestart

安装完C++工具后再使用上面的命令重新安装dlib即可。

这个错误是因为缺少CMake，dlib需要使用CMake进行编译。您需要先安装CMake，然后再重新安装dlib库。以下是在Windows上安装CMake和dlib的步骤：

1. 下载CMake安装程序：您可以从CMake的官方网站 https://cmake.org/download/ 下载适合您的操作系统的CMake安装程序。

2. 安装CMake：运行下载的CMake安装程序，按照提示进行安装。

3. 安装dlib库：在命令行中输入以下命令来安装dlib库：

pip install dlib

如果您已经安装了dlib库，可以使用以下命令卸载它：

pip uninstall dlib

然后再重新安装dlib库：

pip install dlib
