我完全不知道为什么这个错误不断发生，我相当确定我使用了正确的语法，但是，每次我执行这个 BASH 脚本时，我都会收到以下错误：
/home/clucky/MCServerBackup/MCServerBackup.sh: line 200: syntax error near unexpected token `'2''
/home/clucky/MCServerBackup/MCServerBackup.sh: line 200: ` logInfo() '2' "none" "Minecraft: $minecraftsize.$minecraftsized $minecraftunit"'
特别是它似乎正在引用的行是第 200 行，这是代码尝试执行函数的位置logInfo()，如下所示：
logInfo() '2' "none" "Minecraft: $minecraftsize.$minecraftsized $minecraftunit"
在上面的代码行中，2是缩进级别（2 x 5 个空格）。none告诉函数忽略logLevel配置中指定的内容并无论如何记录它。Minecraft: $minecraftsize...$minecraftunit是添加到日志文件中的内容，其中以 $ 开头的单词当然是变量。整个代码可以在下面查看。
