在下面给出的代码中，如果 tcolorbox 有分页符，我想要的左侧灰线就会消失。但是，如果 tcolorbox 没有分页符，则左侧线就会出现。
当 tcolorbox 损坏时，您能帮我让左边的灰线也显示出来吗？谢谢！

frame hidden另一种解决方法。boxrule=0pt不要隐藏框架，而是定义一个leftrule=...在破损的框中幸存下来的特定的框。

我不知道为什么你的 tex 代码不能按预期工作。
exras={frame code={\draw[gray,line width=2mm] ([xshift=-0.5pt]frame.north west) -- ([xshift=-0.5pt]frame.south west);}}我建议使用within 的解决方法彩色盒子选项：
