using fabric to change LD_LIBRARY_PATH

Question

when i login a remote server through ssh, i see the LD_LIBRARY_PATH was :

echo $LD_LIBRARY_PATH
:/usr/local/lib

And when i use fabric in python, to run the same code in fabric run api, the result is empty.

from fabric.api import *
def test():
    run("echo $LD_LIBRARY_PATH")

and even when i try to change the LD_LIBRARY_PATH using fabric, it doesn't work at all.

from fabric.api import *
def test():
    run("echo $LD_LIBRARY_PATH")
    run("export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH")

Does anyone know why?

I had the same problem and here is a way to fix it. You need at least fabric 1.5.4 i think to use shell_env.

with shell_env(LD_LIBRARY_PATH ="/usr/local/lib"):
    run('something')
