如何忽略 pip 中的编译器标志？
How to ignore compiler flags in pip?
我正在尝试安装 mujoco-py，当我在 maxOS 10.12 中尝试 pip install mujoco_py 而在 anaconda 中尝试 python 3.5 时，我得到了

我必须安装 gcc，因为它不接受 clang。看来 gcc 并没有忽略这个未知的标志。我试过了
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install mujoco_py
但这并没有帮助。 gcc 有什么方法可以忽略这个未知标志吗？
我终于找到了解决办法。
首先通过 brew install clang-omp 安装 clang-omp。然后 link clang-omp 通过 sudo ln -s /usr/local/bin/clang-omp /usr/local/bin/gcc-7 到 gcc-7。那么你应该可以 运行 mujoco151。请注意，您可能还需要 brew uninstall glfw 来解决冲突。
