安装中链接错误后的链接：

ostaptan:wand ostap$brew链接imagemagick

Error: Could not symlink file: /usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/wand/wand-view.h

Target /usr/local/include/ImageMagick/wand/wand-view.h already exists. You may need to delete it.

To force the link and delete this file, do:
  brew link -f formula_name

To list all files that would be deleted:
  brew link -n formula_name

如何链接？？？怎么办？？到处都找不到答案

按照brew链接输出中的建议，尝试

brew link -f imagemagick

这将清理

/usr/local/include/ImageMagick/

中的旧链接，然后链接完成安装所需的文件

如果这不起作用，请检查您的用户是否有权限写入

/usr/local/include/ImageMagick/*

在数小时的尝试后，唯一对我有效的方法是：

sudo brew link --overwrite imagemagick

---

（还需要将

/usr/local/bin/brew

更改为

root

）

Homebrew不再支持覆盖sudo命令

sudo brew link --overwrite imagemagick

错误：以root用户身份运行Homebrew非常危险，不再受支持。 由于Homebrew不会放弃安装特权，因此您将提供所有 生成脚本可以完全访问您的系统
