在FreeBSD中执行
make search name = nginx命令时，报错：

The search target requires INDEX-9. Please run make index or make fetchindex

解决方法

转到/usr/ports目录，来搜索FreeBSD ports树。

使用root执行下面命令

cd /usr/ports
make index

或者

cd /usr/ports
make fetchindex

然后重新搜索

# make search name=apache
# make search name=lsof

输出示例：
