Geogebra导出的TikZ带有一行\usetikzlibrary{arrows}并带有>=triangle 45
例如

sec 16.1建议使用 arrows.meta 取代 arrows
The libraries arrows and arrows.spaced are deprecated. Use arrows.meta instead/additionally, which allows you to do all that the old libraries offered, plus much more.
但是把arrows换成arrows.meta后,箭头失效:

如何解决呢?

就是说 arrows 属于旧的 library,不建议再使用?就算目前可能还兼容地能用,或许以后会完全去掉吗?

新的 arrows.meta 语法变了,应该是更一般化了吧,但写起来就会麻烦一点,要用 triangle 45 箭头,好像得 >={Triangle[angle=45:5pt]} 酱紫,5pt 似乎是角的边长,必须指定。

PS、你的 arrows.meta 没加 inlinecode
