解决方案 #

• 检查网络与代理配置
  确认网络能正常访问GitHub，若处于受限网络环境，设置代理环境变量：

  export HTTP_PROXY=http://your-proxy-address:port
  export HTTPS_PROXY=http://your-proxy-address:port
  

• 更新Spack索引与镜像
  先更新包索引，确保包信息是最新的：

  spack repo update
  

  添加Spack官方二进制镜像并导入信任密钥：

  spack mirror add binary_mirror https://binaries.spack.io/v1
  spack buildcache keys --install --trust
  

• 手动下载re2c源码并导入Spack

  1. 下载re2c 2.2版本源码包（如re2c-2.2.tar.xz）
  2. 将下载的包导入Spack缓存：

     spack fetch --path=/path/to/your/re2c-2.2.tar.xz re2c@2.2
     

• 使用系统已安装的re2c（如果有）

  1. 检查系统是否已安装re2c：

     re2c --version
     

  2. 若已安装，编辑~/.spack/packages.yaml，添加外部包配置：

     packages:
       re2c:
         externals:
         - spec: re2c@2.2
           prefix: /usr/local  # 根据实际安装路径调整
         buildable: false
     

• 清理缓存并重新引导
  清理之前失败的构建缓存：

  spack clean --all
  

  重新执行clingo引导：

  spack bootstrap now
  

  之后再尝试安装PISM：

  spack install pism ^petsc~metis~hdf5~hypre~superlu-dist
