我添加了该包，datetime2以便我可以按照 ISO 标准写出今天的时间。
\usepackage[iso]{datetime2}
我收到一个错误，说 iso 未预定义。
datetime2.sty
159
Package tracklang Error: Dialect `iso' is not predefined.
See the tracklang package documentation for explanation.
Type H <return> for immediate help.
...
l.159 \disable@keys
{datetime2.sty}{calc}
我还可以补充一点，我刚开始使用.tex，所以我不知道自己在做什么，只是复制我在互联网上找到的内容。
完整的代码如下，我唯一做的更改是那些中间带有注释的更改。其余的是一个给我的模板。
