命令行工具在尝试安装MuJoCo时会出现许多错误。我非常自信地怀疑这是我的 macOS Catalina 上的命令行工具的问题，因为我之前在 Mojave 和多台 ubuntu 机器上安装了 mujoco。以下装置在莫哈韦工作。
首先我表演：
xcode-select --install

关于为什么我的命令行工具在 macOS Catalina 上失败的任何建议？应该采取哪些步骤来确保 Catalina 上的命令行工具和 gcc 按预期工作？
将以前版本的 OS X sdk 作为 sysroot 传递，而不是未版本化的 sdk。

由于 SDK 目录不正确，命令行工具在 macOS Catalina 上失败。

应该采取哪些步骤来确保 Catalina 上的命令行工具和 gcc 按预期工作？引用版本化的 SDK：
./configure --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk/usr/include/c++/4.2.1和/或./configure --with-sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
