Make sure to clean before, or force recompilation via the stack option --force-dirty and ghc option -fforce-recomp . 确保在之前清理，或通过堆栈选项强制重新编译--force-dirty和ghc选项-fforce-recomp 。
The files are dumped somewhere around .stack-work/dist/.../build/hello_world/hello_world-tmp/ . 这些文件被转储到.stack-work/dist/.../build/hello_world/hello_world-tmp/ 。
