我已经在Mac（OSX 10.9）上设置了一个服务器，但它返回了一个500错误，错误日志中显示以下消息...

[alert] [client ::1] /Users/user/Sites/mysite/.htaccess: AllowOverride not allowed here

下面是.htaccess文件中的代码

Options +FollowSymLinks -MultiViews
AllowOverride All

# Turn mod_rewrite on
RewriteEngine On
RewriteBase /

RewriteMap lc int:toLower
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule (.*) ${lc:$1} [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^i/(.*)/(.*)-(.*)$ /items/?id=$1&range=$2&type=$3 [L,QSA,NC]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^c/(.*)$ /category/?menu=$1 [L,QSA,NC]

下面是相关的httpd.conf代码（如果还有其他有用的代码，请告诉我）

DocumentRoot "/Users/user/Sites/mysite"

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order deny,allow
    Deny from all
</Directory>

<Directory "/Users/user/Sites/mysite">
    Options Indexes FollowSymLinks MultiViews
    AllowOverride All
    Order allow,deny
    Allow from all
</Directory>

有什么想法吗？
