Hi
i tried the way to suggested but i am still getting the same error.
My pharo version is 1.1.1. do you think this may be the reason.
i am attaching a snapshot.
The problem is that the Pharo 1.1.1 already has Metacello installed. But
of course, the metacello of that moment.
The way you are installing OSProcess, i.e
((Smalltalk at: #ConfigurationOfOSProcess) project version: #stable) load.
use the "symbolic" version #stable which is a Metacello feature that was
added to Metacello in a newer version than the one you have in Pharo
1.1.1. So...you have to options:
1) Try to upgrade your Metacello version of your Pharo 1.1.1 to the
latest one. This is what I tried, but failed. THere is a way to upgrade
a package in Metacello but I don't remember now. Maybe other guy now.
The following should upgrade to the correct version of Metacello:
ConfigurationOfMetacello project updateProject.
ConfigurationOfMetacello load.
If this fails, I am interested in a stack and an error report...
What did you try that failed?
2) browse the implementation of #stable and you will see it is :
stable: spec
<symbolicVersion: #'stable'>
spec for: #'common' version: '4.4.0'.
So...you can just evaluate:
((Smalltalk at: #ConfigurationOfOSProcess) project version: '4.4.0') load.
and it should work.
Anyway, I recommend you to read the Metacello chapter I wrote with Stef:
https://gforge.inria.fr/frs/download.php/28462/Metacello.pdf
as you ca find it in http://pharobyexample.org/
