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过这些错误。 我不知道该怎么办！ 感谢您的帮助！
【问题讨论】：
“无法编译简单的测试程序”您的系统上没有安装 gcc 编译器 命令sudo xcode-select --switch path/to/Xcode.app写在错误信息中。
@phd：在 Stack Overflow 上强烈反对编辑输出消息。相反，使用<!-- language: lang-none --> 禁用语法高亮。我已经修复了给定的问题帖子。
【参考方案1】：
检查您的输出。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，如果您知道自己以前安装过它，请指向已安装工具的 Xcode：
sudo xcode-select --switch path/to/Xcode.app
