在 Windows 10 上使用 pip 安装 dlib 失败

Question

我尝试了很多来安装pip install dlib，但它总是显示错误，我重新安装了cmake。

我得到了错误：

Answer 1

执行以下操作：

1.转到github repository of dlib package

2.点击绿色按钮，上面写着克隆或下载

3.然后点击下载压缩包

4.下载完成后，解压zip文件并保存在桌面

注意：首先安装 CMake，然后开始执行其他步骤。

5.去dlib-master/dlib-master复制dlib-master文件夹目录 如果您按照这些步骤操作，您应该是 C:\Users\(you'r username)\Desktop\dlib-master\dlib-master。

6.然后打开pwershell并输入cd C:\Users\(you'r username)\Desktop\dlib-master\dlib-master

注意：如果您没有正确安装 CMake，请考虑安装它，这样您就可以毫无问题地安装 dlib 模块。

7.当您通过输入上述命令更改当前工作目录时，然后输入python setup.py install

8.如果你已经安装了cmake，那么这个包就可以轻松完美的安装了。

Answer 2

这里我得到了那行的错误

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

• 设置CMake路径到环境变量中（如图）

• 安装 Visual Studio 构建工具最新版本 链接：https://visualstudio.microsoft.com/downloads/#build-tools-for-visual-studio-2017

• 安装 Visual Studio 构建工具后，选择需要的包并下载。
• 下载和安装成功后，Visual Studio 安装dlib 通过在 CMD(ADMINISTRATOR) pip install dlib 中的命令

Answer 3

我按照@Moh Vahedi 的说法执行了 setup.py 并在 cmd 中出现以下错误：

您必须使用 Visual Studio 在 Windows 上构建 Python 扩展。 如果您收到此错误，则表示您尚未安装 Visual C++。请注意，Visual Studio 有多种风格，例如 Visual 用于 C# 开发的工作室。您需要安装 Visual Studio C++。

所以我现在正在安装 VS :)
