我遇到了“https://tex.stackexchange.com/questions/566921/cant-locate-algorithm-diff-pm-in-inc-you-may-need-to-install-the-algorithmd”中描述的相同问题，但那里接受的答案没有帮助。
当我在 Windows 10 上从 cmd 运行命令时latexdiff ThesisSubmission_expanded.tex ThesisCorrections_expanded.tex > diff.tex，出现以下错误：
Can't locate Algorithm/Diff.pm in @INC (you may need to install the Algorithm::Diff module) (@INC contains: /usr/lib/perl5/site_perl /usr/share/perl5/site_perl /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl) at C:\Users\Sarah\AppData\Local\Programs\MiKTeX 2.9\scripts/latexdiff\latexdiff line 193.
BEGIN failed--compilation aborted at C:\Users\Sarah\AppData\Local\Programs\MiKTeX 2.9\scripts/latexdiff\latexdiff line 193.
我在 cmd 中进入“C:\Strawberry\perl\bin”并运行perl -MCPAN -e "install Algorithm::Diff"。一切似乎都运行正常：

当我返回到我尝试运行 latexdiff 的目录并输入“where perl”时，我得到输出：
C:\Program Files\Git\usr\bin\perl.exe
C:\Strawberry\perl\bin\perl.exe
这表明它使用的是 Git 安装附带的 Perl 版本，而不是 Strawberry Perl，但是当我尝试在 Git 安装的各个子文件夹中安装 Algorithm/Diff 时，出现错误消息。
谢谢你！
