我正在尝试在与 Texlive 一起运行的 Texworks 中使用 Stone Sans 和 Serif 字体。我将字体包的文件下载到相关文件夹，但惊讶地发现以下错误消息：

I try ps2pk --> gsftopk --> ttf2pk --> hbf2gf.
ps2pk cannot be used.
I try gsftopk.
gsftopk.exe pstr8r 657
gsftopk cannot be used.
Next I try ttf2pk.
ttf2pk.exe -q pstr8r 657
ttf2pk failed.
Finally I try hbf2gf.
hbf2gf.exe -q -p pstr8r 657
All trials failed.

!pdfTeX error: pdflatex.exe (file pstr8r): Font pstr8r at 657 not found
==> Fatal error occurred, no output PDF file produced!
有没有什么办法解决这一问题？
