\usepackage[scaled]{helvet} 在 Mac 上使用 BasicTeX 失败

Question 1

TeX Live 提供tlmgr更新、维护和管理安装。如果您最初没有安装完整的 TeX 安装，则可以使用它升级到更大的版本scheme或安装特定的collections或packages。

TeX Live 软件包名称通常与 eg 发行版打包 TL 时使用的名称不一致。因此您需要做一些侦查工作来弄清楚要tlmgr安装什么。

tlmgr help

详细介绍了该设施的所有优点。您可以说

tlmgr info

获取的列表packages。但是，这会很大。相反，尝试

tlmgr info collections

collections获取（相关软件包组）列表。在我的系统上，我获取

tlmgr: package repository http://mirror.ox.ac.uk/sites/ctan.org/systems/texlive/tlnet
i collection-basic: Essential programs and files

i collection-xetex: XeTeX and packages

这将向我显示我正在使用的存储库、collections可用的存储库以及已安装的存储库（标记为i）。由于我安装了完整版的 TeX，因此几乎所有存储库都安装在这里。如果您安装了较小的版本，则会有较少的is。有几个collections提到了字体：

i collection-fontsextra: Additional fonts
i collection-fontsrecommended: Recommended fonts
i collection-fontutils: Graphics and font utilities

最后一个听起来不太可能。前两个是可能的。Helvetica 相当标准，因此很可能会推荐它。所以从那里开始是有意义的。要获取有关的信息collection和列表，packages它包括：

tlmgr info --list collection-fontsrecommended

这让我

现在您可以决定是安装整个集合还是安装选定的包。或者，您当然可以请求有关特定包的更多信息：

tlmgr info helvetic
