Answer 1

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

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

3）texi2html-1.82.tar.gz（其e7bbe1197147566250abd5c456b94c8e37e0a81f）的测量shasum并将其放入/usr/local/Library/Formula/texi2html.rb中的sha1标签

现在brew install ffmpeg工作正常
