Answer 1

1) 搜索工作镜像http://www.filewatcher.com/m/texi2html-1.82.tar.gz.7350232-0.html => 例如ftp://ftp.mirrorservice.org/sites/distfiles.macports。 org/texi2html/texi2html-1.82.tar.gz

2) 将此路径放在 /usr/local/Library/Formula/texi2html.rb 中的 url 标签

3) 计算 texi2html-1.82.tar.gz (其 e7bbe1197147566250abd5c456b94c8e37e0a81f) 的 shasum 并将其放在 /usr/local/Library/Formula/texi2html.rb 的 sha1 标记中

现在 brew install ffmpeg 工作正常
