错误消息 pgfplots pgfkeyscurrentname

Question

我想绘制一张 pgfpicture，并在其上添加一些图片文件。

使用下面的代码，我收到以下错误消息：

软件包 pgfkeys 错误：我不知道密钥“/pgf/decoration/\p gfkeyscurrentname”，我将忽略它。也许您拼错了。请参阅 pgfkeys 软件包文档以获取解释。键入 H 可立即获得帮助。... l.97 \Item R 2pt (180:-40)

我需要在下面的代码中更正或添加什么？

添加或删除你的 之后的\usetikzlibrary{decorations.text}额外内容。}\caption[]{}

您可能需要稍微清理一下您的序言，您多次加载了多个包。
