在 conda 环境下pip install mpi4py安装 mpi4py 库时出现编译报错，报错信息为：
line 301: x86_64-conda_cos6-linux-gnu-cc: command not foundfailure.removing: _configtest.c _configtest.oerror: Cannot compile MPI programs. Check your configuration!!![end of output]note: This error originates from a subprocess, and is likely not a problem with pip.ERROR: Failed building wheel for mpi4pyFailed to build mpi4pyERROR: Could not build wheels for mpi4py, which is required to install pyproject.toml-based projects
所以导致该错误的原因是
x86_64-conda_cos6-linux-gnu-cc: command not found
即没有找到x86_64-conda_cos6-linux-gnu-cc。只需执行以下命令安装即可：
conda install gcc_linux-64
安装完成后重新执行pip install mpi4py即可完成安装。
