电脑配置：我的电脑是maosx系统，在虚拟机安装ubuntu，原系统安装天梯（VPN），Linux没有安装成功天梯（VPN）。
环境配置：在虚拟机中安装petsc，下载petsc软件包解压，安装GCC，gfortran，之前分别下载MPI和BLAS/LAPACK，但是安装MPI的时候出现错误。.
./configure --with-cc=gcc --with-cxx=g++ --with-fc=gfortran --download-mpich --download-fblaslapack
命令行执行，结果显示无法从网站下载MPI（我试过下载url，安装梯子（VPN）后可以下载。下面是输入命令和结果：
