在 Pycharm 上安装 dlib 时出错

我正在尝试安装dlib在 Pycharm（类似于 Anaconda）上，以便将其用于我的 Python 和 OpenCV 人脸检测项目。

我已经安装了 cMake 并升级了 Python，但仍然出现错误：

命令

pip install dlib

错误

FileNotFoundError: [WinError 2] The system cannot find the file specified

You are using pip version 10.0.1, however version 19.0.3 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

答案1

  1. 安装 Pycharm
  2. Windows 10
  3. Python 3.8.3（带有 pipenv，但也可以与 pip 一起使用）

例如：pipenv 安装（作为虚拟环境）

由于“pipenv install dlib”在尝试了一段时间后出现了安装错误，因此能够安装最新的 dlib 库（dlib==19.20.0）

下面是帮助我成功安装最新 dlib 的步骤 - 我们必须手动为 Python 编译 dlib

  1. 安装Visual Studio（我安装的是Microsoft Visual Studio Community 2019版本16.6.3）
  2. 确保选择 Visual C++ 或 C++ 环境 - 完成安装 - 不需要其他任何东西（在 Visual Studio 2019 中，转到单独组件选项卡、Cmake 的 Visual C++ 工具，然后选中“编译器、构建工具和运行时”部分下的复选框。）
  3. 去 -https://cmake.org/download/并下载 64 位的 cmake （我安装的是 cmake-3.18.0-rc4-win64-x64.msi）
  4. 安装时，请确保将 CMake 添加到系统路径（安装完成后 -> 检查环境变量是否存在）
  5. 去https://pypi.org/project/dlib/-> 点击“下载文件”
  6. dlib-19.20.0.tar.gz（我最新的版本）-> 下载相同的
  7. 提取文件“dlib-19.20.0.tar.gz”直到看到文件（dlib，dlib.egg-info，python_examples，tools，MANIFEST.in，PKG-INFO，README.md setup.cfg，setup.py）
  8. 复制所有这些文件（全选（ctrl+a）并复制（ctrl+c））-> 确保只复制这些文件，而不复制其父目录
  9. 转到 python 安装中的站点包（C:\Users<name>\AppData\Local\Programs\Python\Python38\Lib\site-packages）
  10. 粘贴步骤7、8中复制的所有文件
  11. 打开命令提示符并转到 -> C:\Users<name>\AppData\Local\Programs\Python\Python38\Lib\site-packages
  12. 执行命令 -> python setup.py install

这就是您应该完成的所有操作 - 完成该过程可能需要 5 - 10 分钟，最后您应该会看到类似下面的内容 已安装 c:\users<name>\appdata\local\programs\python\python38\lib\site-packages\dlib-19.20.0-py3.8-win-amd64.egg 正在处理 dlib==19.20.0 的依赖项 已完成处理 dlib==19.20.0 的依赖项

答案2

我收到此错误，您能告诉我原因吗？我已经为 CMAKE 安装了 Visual C++ 工具，但没有编译器、构建工具和运行时之类的东西

我发现错误是python是32位而编译器是64位，但是如何修复它
