Description Alex Corrado [MSFT] 2012-02-27 18:25:11 UTC
The IronPython that is bundled with Mono on the Mac does not include any Python built-in modules. This was observed in Mono 2.10.6 and 2.10.8 for Mac:

 $ ipy
IronPython 3.0 (3.0.0.0) on .NET 4.0.30319.1
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named os

Duncan, any updates?
Comment 2 Zack Gramana 2014-10-22 18:14:50 UTC
Bump. Problem is still there:

> ipy -V
IronPython 3.0 3.0.0.0 on 3.10.0 ((detached/e204655 Mon Oct 13 08:50:28 EDT 2014)

As of today, latest stable release is 2.7.4, and current beta is only 2.7.5-beta2.
Comment 3 Alexander Köplinger [MSFT] 2016-03-01 13:06:43 UTC
This seems to work now on Mono 4.4:

>   alexander:~$ ipy
>   IronPython 3.0 (3.0.0.0) on .NET 4.0.30319.42000
>   Type "help", "copyright", "credits" or "license" for more information.
>   >>> import os
>   >>> os.name
>   'posix'

Actually I am having difficulty finding out what exact version of Ironpython is shipped with the Mono binaries (does not seem to be in the source?) and how it was built, since I am having problems building ironpython3 on linux, but using those from windows mono seem to work. Care to enlighten me?
Comment 5 Alexander Köplinger [MSFT] 2016-05-17 14:48:44 UTC
@Hin-Tak Leung: according to https://github.com/mono/bockbuild/blob/master/packages/ironlangs.py (which is the script we're using to build the package) we're shipping commit de63773744ccf9873c1826470730ae0446fd64d7.
Comment 6 Hin-Tak Leung 2016-05-17 19:53:57 UTC
@Alexander Köplinger : Thanks for the notes! I have had that script in my radar but it is somewhat surprising - it claims to be 3.0 on -V but rather behind (nearly 5 years old). It is 577 commits behind master and 614 behind ipy-2.7-maint (and 130 from the last common ancestor with ipy-2.7-maint) as of now. It is also a bit surprising it claims to be 3.0 but did not come from git://github.com/IronLanguages/ironpython3.git .

I tried git://github.com/IronLanguages/ironpython3.git and had some difficulty building it; and most current activity seems to be on git://github.com/IronLanguages/main.git:ipy-2.7-maint - would it make sense to switch to git://github.com/IronLanguages/main.git:ipy-2.7-maint or one of its release tags instead?
Comment 7 Alexander Köplinger [MSFT] 2016-05-17 21:49:02 UTC
@Hin-Tak Leung: if you look at the AssemblyVersion.cs from the commit we're using then it is 3.0: https://github.com/IronLanguages/main/blob/de63773744ccf9873c1826470730ae0446fd64d7/Languages/IronPython/AssemblyVersion.cs

I agree that it is quite old, can you please file a new bug for upgrading as this doesn't have anything to do with this issue?

Thanks - bug filed.

About the versioning - I came to this bug report initially when I was searching for any version info of the bundled ironpython - this bug report was the only find.

ironpython 2.6 was a bit clearer the version has nothing to do with python version:

$ mono bin/ipy.exe -V
PythonContext 2.6.10920.0 on 4.2.2 (Stable 4.2.2.30/996df3c Sun Feb 14 19:54:12 GMT 2016)

(I am using ironpython 2.6 as it was the last release which supports a dotnet v2 runtime).
