Mac安装MJX卡在Wheels构建求助及mujoco-mjx安装疑问

问题描述 #

在Mac设备上完成Mujoco安装后，尝试安装MJX时每次卡在Wheels构建环节无法推进，先后尝试Python 3.12和3.10版本，已更新Xcode但问题仍未解决。同时咨询：是否可以安装mujoco-mjx？它是否同时包含Mujoco和MJX？

解答 #

关于mujoco-mjx的疑问 #

可以安装mujoco-mjx，它是官方推出的整合包，同时包含Mujoco核心库和MJX的全部功能。安装这个包可以跳过单独编译MJX的步骤，直接使用完整的Mujoco+MJX环境，是解决当前编译卡住问题的最优方案，推荐优先尝试：

pip install mujoco-mjx

解决单独安装MJX时Wheel构建卡住的办法 #

如果仍想单独安装MJX，可尝试以下步骤：

• 安装CMake依赖：MJX构建需要CMake，通过Homebrew安装：

  brew install cmake
  

• 替换grpcio版本：日志中使用的grpcio 1.39.0在ARM架构Mac上编译容易卡顿，尝试指定兼容版本：

  pip install mjx grpcio==1.56.0
  

• 清理pip缓存：删除旧缓存后重新安装，避免缓存干扰：

  rm -rf ~/Library/Caches/pip
  pip install mjx
