！！./configure --with-php-config=/usr/local/php/bin/php-config 出现错误
configure: error: not found. Please provide a path to MagickWand-config or Wand-config program.
安装如下软件即可：
yum install ImageMagick-devel
在安装 ImageMagick-devel 又出现错误：
Transaction check error:file /usr/lib64/libgs.so.9 from install of libgs-9.25-2.el7_7.3.x86_64 conflicts with file from package ghostscript-9.07-18.el7.x86_64
file /usr/lib64/libijs-0.35.so from install of libgs-9.25-2.el7_7.3.x86_64 conflicts with file from package ghostscript-9.07-18.el7.x86_64
安装包冲突（文档转换器，我这边不需要，可以直接卸载）：
先删除 yum remove ghostscript-9.07-18.el7.x86_64
再 yum install ImageMagick-devel
再 pecl install imagick 这个命令等于第3大步所有命令。
Build complete.
Don't forget to run 'make test'.
