无法使用 pip install Dlib 安装 Dlib,它给了我这个错误:

我在 macOS Catalina 10.15.3 上。我安装了 Anaconda 和 cmake。我对堆栈溢出很陌生。我安装了多个版本的python(我不知道这是否有问题)我主要使用3.7。
我以前从未在论坛上看到这些错误。我不知道该怎么办!谢谢您的帮助!
解决方案
检查你的输出。控制台具体告诉你:
It fails with the following output:
Change Dir: /tmp/pip-install-884s1u35/dlib/build/temp.macosx-10.9-x86_64-3.7/CMakeFiles/CMakeTmp
Run Build Command(s):/usr/bin/make cmTC_f5f8f/fast && xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist
Use `sudo xcode-select --switch path/to/Xcode.app` to specify the Xcode that you wish to use for command line developer tools, or use `xcode-select --install` to install the standalone command line developer tools.
See `man xcode-select` for more details.
CMake 需要 XCode 命令行开发人员工具才能构建项目。
所以打开终端,然后运行:
sudo xcode-select --install
或者,如果您知道之前已经安装过它,请指向已安装工具的 Xcode:
sudo xcode-select --switch path/to/Xcode.app
