ImageMagick无法正常工作。 “调用未定义的函数NewMagickWand()”

I installed ImageMagick following the instructions on this site.

When I check my phpinfo() there is a whole section on imagick now.

imagick module  enabled
imagick module version  3.0.1
imagick classes Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator
ImageMagick version ImageMagick 6.5.7-8 2010-12-02 Q16 http://www.imagemagick.org
ImageMagick copyright   Copyright (C) 1999-2009 ImageMagick Studio LLC
ImageMagick release date    2010-12-02
ImageMagick number of supported formats:    202

However when I try to use it I get this error:

Fatal error: Call to undefined function NewMagickWand()

I have never used image magick before.

Did I not install it right? Is there more extensions I need to install?

You need the MagickWand module/extension installed for it to work. See: http://www.magickwand.org/
