dyld: Library not loaded error when running command in terminal

When running some commands in the terminal, I get the following error message

dyld: Library not loaded开发者_运维知识库: /opt/local/lib/libjpeg.62.dylib
  Referenced from: /opt/local//lib/libTIFF.dylib
  Reason: no suitable image found.  Did find:
    /opt/local//lib/libjpeg.62.dylib: can't map
    /opt/local/lib/libjpeg.62.dylib: can't map
Trace/BPT trap

My xcode is up to date.

As your paths begin /opt/local I assume you are using macports

If so I think you need to at least do a sudo port selfupdate as the current tiff port depends on /libjpeg.7.dylib.

Possible a complete reinstall is needed if the macports was installed under Leopard or earlier

After you do your

sudo port selfupdate 

don't forget to do a

sudo port upgrade outdated

to upgrade your existing ports. Much better than reinstalling everything :-)

On my Leopard machine using macports, libsdl_image was looking for this non-installed jpeg lib. The jpeg6b port includes it, but at a different path (/opt/local/lib/jpeg6b/lib/libjpeg.62.dylib). I fixed it by doing

port selfupdate
port install libsdl_image

which upgraded libsdl_image from 1.2.8_0 to 1.2.10_2 and made the problem go away.

I had the same problem. I have never runned anything else than Snow Leopard. I have tried all kind of stuff and used about 10 hours trying to fix this problem, but with no success.

I ended up removing macports completely and installed it again.

This is what I did:

First I got a list of all my installed ports:

> port installed

Then I uninstalled everything:

> sudo port -f uninstall installed

And installed macports again: macports and installed all my packages again.

It was rather tedious, but it did the trick.
