看起来magic_open失败了吗？我该如何解决这个问题？
答案 0 :(得分：0)
sudo brew install libmagic为我解决了这个问题
答案 1 :(得分：0)
AAA， 找到了帮助我的解决方案，花了将近两天的时间，所以如果能节省一些时间在这里发布。
brew install libmagic
然后
env ARCHFLAGS="-arch x86_64" gem install -v 0.7.1 ruby-filemagic -- --with-magic-include=/usr/local/include --with-magic-lib=/usr/local/lib/
确保，但您要在gem install -v 0.7.1 ruby-filemagic
