因此，我使用bbm包将原始格式扩展\mathbb{}到amssymb非大写字母区域。这在普通部分工作正常。但是，当我尝试更改数学模式的大小时，它LaTeX告诉我它找不到相应的字体。以下是平均能量损失

只有未注释的行才能给出正确的输出。所有注释的行都给出致命错误，甚至 PDF 文件都不会弹出。我不知道为什么。.log文件对于错误版本都看起来像

唯一的区别是，这里bbm9是\small，如果我们想使用其他字体大小，我们会相应地找到其他的。
但是，我已经检查过所有这些声称丢失的字体都存在/usr/local/texlive/2021/texmf-dist/fonts/source/public/bbm。（顺便说一句，如果这有帮助的话，我使用的是 MacOS 10.15.7）
