r - 如何解决extrafont中的错误状态5？

Question

我的目标是使用字体xkcd.tff。我检查它是否安装在目录中

C:/Users/prgca/AppData/Local/Microsoft/Windows/Fonts

曾经我

font_import(path = "C:/Users/prgca/AppData/Local/Microsoft/Windows/Fonts",
             pattern = "xkcd")

这是输出

Scanning ttf files in C:/Users/prgca/AppData/Local/Microsoft/Windows/Fonts ...
Extracting .afm files from .ttf files...
C:\Users\prgca\AppData\Local\Microsoft\Windows\Fonts\xkcd.ttf : No FontName. Skipping.
Found FontName for 0 fonts.
Scanning afm files in C:/Users/prgca/Documents/R/win-library/4.1/extrafontdb/metrics
Warning message:

字体确实没有加载到我的图中。 我怎样才能加载它？

我怀疑这与 Rttf2pt1(extrafont 所依赖的)问题有关，如 here 中所述。和 here 。对我有用的建议解决方案是降级 Rttf2pt1，如下所示:

remove.packages("Rttf2pt1")   
remotes::install_version("Rttf2pt1", version = "1.3.8")
