在STEAM的讨论社区找到的解决方法。大家可以试一下。 I can verify it's not working because of Steam Beta. Go to Steam > Settings > Account > Beta Participation Make sure you opt out of the beta updates When I did that, Steam prompted to restart, installed the current stable release and the input worked again! Happy gaming! 我可以验证它不工作,因为蒸汽测试。 进入Steam>设置>帐户>测试版参与 确保您选择退出测试版更新 当我这样做时,Steam提示重新启动,安装了当前的稳定版本,输入再次工作! 游戏快乐!
