ChemPy：clang：错误：不支持的选项“-fopenmp”
我正在尝试解决以下问题。当我尝试在此 ntb中运行以下行时，我得到：
native = get_native(rsys, odesys, 'cvode')
INFO:pyodesys.native._base:Cythonizing /Users/user/Library/Caches/python3.8-pyodesys-0.13.1/_cvode_wrapper.pyx to ./_cvode_wrapper.cpp

fopenmp我认为这可能是和 的问题gcc，如这些地方所述（How to deal with "clang: error: unsupported option '-fopenmp'" on travis?，https://github.com/microsoft/LightGBM/issues/ 3、 https: //github.com/velocyto-team/velocyto.R/issues/2）但提出的解决方案（https://github.com/velocyto-team/velocyto.R/issues/2#issuecomment-341165967，https://github.com/microsoft/LightGBM/issues/3#issuecomment-254149689，https : //github.com/kharchenkolab/conos/wiki/Installing-Conos-for-Mac-OS）只是不适用于我。我也尝试使用 conda 安装 GCC 但我得到：
conda install gcc
PackagesNotFoundError: The following packages are not available from current channels: - gcc Current channels: - https://repo.anaconda.com/pkgs/main/osx-64 - https://repo.anaconda.com/pkgs/main/noarch - https://repo.anaconda.com/pkgs/r/osx-64 - https://repo.anaconda.com/pkgs/r/noarch
使用homebrew我已经gcc安装...知道发生了什么以及如何修复它吗？我运行的是 MacOS 10.15.7。谢谢

我花了很长时间，最终出现了两个我认为对其他人可能有用的主要问题。ChemPy 仅在 Linux 上受支持，因此即使我让编译器正常工作，我也没有使其在 Mac 或 Windows 上运行。编译器一团糟。最后有效的是使用 Anaconda 环境中的 clang v10 而不是 v12：export CC=/usr/bin/clang export CXX=/usr/bin/clang++为了使它完整，这里是现有的和工作的：(base) bash-3.2$ clang --version clang version 10.0.0 Target: x86_64-apple-darwin19.6.0 Thread model: posix InstalledDir: /Users/user/anaconda3/bin (base) bash-3.2$ which clang /Users/user/anaconda3/bin/clang
