python - 安装 dlib/face_recognition 时出现 VS 代码错误

Question

pip install dlib
Collecting dlib
  Using cached dlib-19.21.0.tar.gz (3.2 MB)
Using legacy 'setup.py install' for dlib, since package 'wheel' is not installed.
Installing collected packages: dlib
    Running setup.py install for dlib ... error

我只是想在 cmake 之后下载 dlib。 我已经下载了 cmake 并尝试了 dlib...

      You must use Visual Studio to build a python extension on windows.  If you
      are getting this error it means you have not installed Visual C++.  Note
      that there are many flavors of Visual Studio, like Visual Studio for C#
      development.  You need to install Visual Studio for C++.

在这里检查了一下，实际上看到了一个解决方案：https://stackoverflow.com/a/63648302/13692454

但这是一个新问题，我使用的是 VS 代码，即使我下载了 C++ 扩展，它也无法修复。我不知道该怎么做。我怎样才能解决这个问题？谢谢指教..

Answer 1

刚刚使用 google colab 解决了这个问题。找不到VS代码的解决方案...
