根据导入mujoco\u py时 this 在文档中,cymj扩展构建失败,出现了一个clang-10错误(见下文)。执行此操作时也会发生此错误 brew uninstall gcc && brew install gcc@x (x为6,8,9)。执行此命令也没有帮助: conda install -c conda-forge openmp 。在运行这些命令之前,Pip和brew已更新/升级至最新版本。mujoco builder中的gcc-9编译器行(以及版本7和8的编译器行)。py处于活动状态。&应用sdk文件夹副本;从此重命名技巧 issue 也没有帮助。

以下是完整的标准输出/标准输出:

将此用作参考( https://reviews.llvm.org/D74784 )我自己刚刚经历了这场头痛。似乎有一个问题 ld 存在旧的默认选项时 -platform_version 这是不赞成的。

尽管从事LLVM工作的优秀人员修复了它,但我的问题是LLVM会说它是最新的。为了让它再次工作,我必须运行以下命令:

brew reinstall llvm

如果卸载LLVM(并在 .zshrc 如果强制重新安装方法对您不起作用,它也应该起作用。对于我来说,没有LLVM的默认叮当声是:
