i wonder if there is some strange code in the plugin regarding a
result set by MPxCommand.setResult() that works in MEL but cannot be
converted into a python object by mel.eval?
but still, why not call this command from maya.cmds as chris suggested?
maya.cmds.cacheDeform(ts=True, p="c:/teste")

Tnx folks for help me unhappy the problem isn`t the "/"character
nor the single quoting
another test with the suggestions
#
doCreateCacheCommand = 'cacheDeform -ts -p "c:/teste"'
mm.eval(doCreateCacheCommand)
#maya return
mm.eval(doCreateCacheCommand)
// Successfully wrote deform cache file for all objects //
# Error: Error occurred during execution of MEL script

again the plugin works but after end its functions . maya return a
error !

The single/double quoting could do the job, but in my local test the
escape character "\" works.
//MEL
global proc createSphere(string $name){
sphere -n $name;
}
#PYTHON
import maya.mel as mel
cmd = "createSphere \"test\""
mel.eval(cmd)
I tested this with a simple function - perhaps custom commands with
flags work differently...

in python strings the \ character represents a continue line
(meaning: the string is continued on the next line)
when making a command string in python you can write it this way
doCreateCacheCommand = 'cacheDeform -ts -p "c:/teste";'
the string is wrapped in single quotes with double quotes inside the
string not being evaluated util eval call is made on them
I can not test if this is your fix but it looks like it

I got some problems when I call Mel commands from Python . always I
got some return error
some examples :
import maya.mel as mm
doCreateCacheCommand="cacheDeform -ts -p \"c:/teste\" "
mm.eval(doCreateCacheCommand)
// Successfully wrote deform cache file for all objects //
# Error: Error occurred during execution of MEL script
# Traceback (most recent call last):
# File "<maya console>", line 3, in <module>
# RuntimeError: Error occurred during execution of MEL script #
this plugin is wrote using c++ API e create "cacheDeform" mel command
when it is called using python it works well , but after it ends
its functions I`ve got a RuntimeError
as you can see in :
// Successfully wrote deform cache file for all objects //
the plugin is working
when a call it usin only MEL I got no return error
cacheDeform -ts -p "c:/teste";
// Successfully wrote deform cache file for all objects //
I have another question . is it possible create python commands using
API Mfn instead mel commands ?
