假设您通过以下方式安装了Imagemagick
brew install imagemagick但它不会进入您的PATH。例如，我运行失败
compare由于imagemagick不在PATH：中-bash: compare: command not found。
该命令ls -l /usr/local/bin/compare给出
ls: /usr/local/bin/compare: No such file or directory我的.bash_profile
if [ -f ~/.bashrc ]; then
source ~/.bashrc
fi
# http://apple.stackexchange.com/a/53058/15504
export PATH=/usr/bin:/usr/local/bin:/opt/local/sbin:$PATH回声$PATH给
/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin:/usr/local/git/bin:/usr/texbin这似乎还可以，因为/usr/local/bin/在那里。
我系统中的ImageMagick-4ae1e1的答案
命令brew --prefix给出/usr/local就可以了。
该命令brew info imagemagick给出

我运行命令 brew link imagemagick并得到
Linking /usr/local/Cellar/imagemagick/6.9.0-3...
Error: Could not symlink bin/convert
Target /usr/local/bin/convert
already exists. You may want to remove it:
rm '/usr/local/bin/convert'
To force the link and overwrite all conflicting files:
brew link --overwrite imagemagick
To list all files that would be deleted:
brew link --overwrite --dry-run imagemagick这似乎很奇怪。您如何解决这个问题？
我运行命令brew reinstall imagemagick并得到

如何解决有关symlink的错误？
你尝试了什么？你在哪里被困？您知道如何使用命令行吗？您已阅读ImageMagick手册页吗？您在解决这个问题上没有给我们太多帮助，因此很难知道如何为您提供帮助。我们希望您在进行询问之前先认真努力，并向我们展示您尝试过的内容和发生的问题。

基本上，您只需使用所需的选项从Terminal运行它。从您的问题尚不清楚从Terminal运行是否失败，是否不知道如何使用它来完成特定任务或是否有其他问题。因此，请通过编辑问题进行澄清，然后将其自动放入重新打开的队列中。
