【问题描述】：
我在子进程下运行 Minecraft 服务器以使用 python 脚本中的输出。
mc_dir = \'C:\\\\Users\\\\aiche\\\\Desktop\\\\server\'
mc_start_cmd = \'java -Xms1G -Xmx1G -jar server.jar --nogui\'
server = subprocess.Popen(mc_start_cmd, shell=True, stdout=subprocess.PIPE, cwd=mc_dir)
但是当我启动服务器时，我得到了这个日志：
Starting net.minecraft.server.Main

为什么 server.jar 不能使用这些文件以及如何修复它？
-
你能确认（例如使用任务管理器）没有其他 Minecraft 服务器在同一台机器上运行吗？重启机器有用吗？
-
检查你的任务管理器，看看你是否没有在后台运行另一个我的世界服务器。此外，如果您在另一个应用程序中打开了日志文件，请关闭该应用程序。正如 Wander 所说，重新启动可能会解决它（强硬的方式）
