我遇到了一个严重的问题，导致我现在无法使用 LaTeX。我在 Windows 上重新安装了 MiKTeX（内部版本 2.9.7206）和 Texmaker（内部版本 5.0.4）。当我尝试包含.eps通过 chemdraw 软件（内部版本 15.1）生成的文件时，chemdraw 文档中的原始字体（例如 Arial）会更改为 LaTeX 字体样式。此外，如果我想将数字加粗，该数字会在创建的.pdf文件中完全消失。似乎 LaTeX 无法识别 chemdraw 生成文件的字体.eps，因此会替换它。2017 年旧版本的 MiKTeX 或 Texmaker 并未出现此问题。附件中您可以找到 chemdraw 文件（https://workupload.com/file/K9A3b5Bn) 和另存为 eps 文件的相同文件 (https://workupload.com/file/4REEBTWh）。
更新：我通过网络安装程序安装完整的 miktex 解决了这个问题！

答案1
您系统上的 GhostScript 安装配置不正确。您test.eps明确指出应使用 Helvetica，但未包含在内：
%%DocumentFonts: Helvetica
仍然声称test-eps-converted-fto.pdf使用了 Helvetica：
pdffonts test-eps-converted-to.pdf
name type encoding emb sub uni object ID
------------------------------------ ----------------- ---------------- --- --- --- ---------
IROFMT+Helvetica Type 1C WinAnsi yes yes no 8 0
但是，如果将（二进制）PDF转换回（ascii）PostScript，则会pdftops发现：
%%BeginResource: font IROFMT+Helvetica

不知何故，您的 GhostScript 不知道 Helvetica，并用 GhostScript 附带的 Courier 克隆替换了它。应该使用 Helvetica 克隆 Nimbus Sans L，而不是 Nimbus Mono L。
不幸的是，我对 Windows 上的 GhostScript 了解不够，无法提供解决此问题的方法。
