IronPython.StdLib is not loaded in Dynamo3+

[Cyril-Pop]

Hi,

Dynamo version

DynamoSanbox 3.4.1

IronPython version

2.7

DynamoIronPython2 Package version

3.2.1

Operating system

Win 10

What did you expect to see?

IronPython.StdLib is not loaded by default

code to reproduce

import sys
import clr
try:
    import functools
except Exception as e:
    OUT = e, sys.version, sys.path

workaround adding the correct StdLib path in sys.path

     
import sys
import clr
import System
clr.AddReference("System.Core")
clr.ImportExtensions(System.Linq)
#
ipy2_assembly = System.AppDomain.CurrentDomain.GetAssemblies().FirstOrDefault(lambda a : a.GetName().Name == 'IronPython.Modules')
assembly_ipy2_Directory = System.IO.Path.GetDirectoryName( ipy2_assembly.Location )
parent_ipy2_Directory = System.IO.Directory.GetParent(assembly_ipy2_Directory).FullName
#
if System.IO.Directory.Exists(parent_ipy2_Directory + "\\lib"):
	sys.path.append(parent_ipy3_Directory + "\\lib")
if System.IO.Directory.Exists(parent_ipy2_Directory + "\\extra\\lib"):
	sys.path.append(parent_ipy2_Directory + "\\extra\\lib")
if System.IO.Directory.Exists(parent_ipy2_Directory + "\\extra"):
	sys.path.append(parent_ipy2_Directory + "\\extra")
    
import functools
import io
