Question

所以我试图将自动备份添加到我的Minecraft服务器，并且我正在使用bash脚本，该脚本可以自动保存世界并将其保存在云存储中。每当我运行脚本时，都会出现此错误：

引发错误，v＃表达式无效 sre_constants.error：字符范围错误

在听说这是Python 2.7问题后，我已经安装了Python 3，并且脚本始终以相同的错误运行2.7。

Python版本：2.7.13（使用）和3.5.3。 Debian Linux

bash脚本：

#!/bin/bash
screen -r mcs -X stuff '/save-all\n/save-off\n'
/usr/bin/gsutil cp -R ${BASH_SOURCE%/*}/world gs://[terits-smp-minecraft-minecraft-backup]/$(date "+%Y%m%d-%H%M%S")-world
screen -r mcs -X stuff '/save-on\n'

到目前为止，我一直在使用本指南为我提供帮助，因为我不太了解Google Cloud： https://cloud.google.com/solutions/gaming/minecraft-server#schedule_backups

Answer 1

此错误raise error, v # invalid expression由gsutil触发。这是因为您未遵循Make R Studio plots only show up in new window

这部分无效$(date "+%Y%m%d-%H%M%S")，因为您使用的是gsutil实际使用的通配符，并且您还会在名称中留下不被接受的空格。

我建议您在批处理的另一步骤中获取日期和时间，然后将其作为字符串直接添加到gsutil命令中。

从Google Cloud SDK接收“错误字符范围”错误
