包 textcomp 错误：符号 \textlangle 未由 [\textlangle] 提供

Question

在我的论文中，我在尖括号中引用了许多正字法形式。到目前为止，我只是在 (<word>) 后输入尖括号和一个显式空格，但我想切换到一些更美观的尖括号，我可以通过一个命令来输入，该命令会自动包含空格，并允许我同时更改所有形式的排版（例如\Angular{word}）。

从这篇文章：[https://tex.stackexchange.com/questions/48448/angle-brackets-in-non-math-mode-text]我想到使用textcomp 包中的\textlangleand命令并定义一个这样的新命令：\textrangle

\usepackage{textcomp,xspace}
\newcommand{\Ang}[1]{\textlangle\xspace{#1}\textrangle\xspace}

在我进行测试的文章类文档中，它运行良好，但在我的论文的更大的报告类文档中，我得到了错误：“

Problem with textcomp package - Symbol \textlangle not provided by
[\Angular{word}]

我也尝试直接在文档中输入\textlangle和\textrangle，但收到错误：

Symbol \textlangle not provided by
[\textlangle]

我的序言中是否有一些内容与 textcomp 包和新命令相抵触，或者可能存在什么问题？

我的序言如下所示（如果看起来很乱，我很抱歉，每次我在写论文时遇到新的问题需要解决时，我都会添加新的包和命令，但不知道是否有办法让序言更“有条理”？）：
