imagemagick error when run from bash script on Mac OSX

问题

I want to run the following script in bash 3.2.57(1):

#!/bin/bash
basename=abc
convert  $basename.pdf $basename.png

I get the following error:

dyld: Library not loaded: /ImageMagick-7.0.8/lib/libMagickCore-7.Q16HDRI.6.dylib
  Referenced from: /Users/XXX/Applications/ImageMagick-7.0.8/bin/convert
  Reason: image not found
./batch_convert.sh: line 22: 46228 Abort trap: 6           convert $basename.pdf $basename.png

When I run the same 2 commands (setting the variable and convert), I get no error.

Why is this happening?

回答1:

Using IM 7.0.8.59 Q16 Mac OSX Sierra, this works for me.

create a pdf

magick logo: logo.pdf

create a script called test.sh

#!/bin/bash

xxx="logo"
magick $xxx.pdf $xxx.png

run script by typing its name in a bash terminal

bash test.sh

Try that and report if that works. I was working from my desktop. So the script and pdf file were on my desktop.

Note that logo: (with the colon) is an ImageMagick internal image. So it is available from anywhere.
