Unable to do anything

[Charles Dumont]

Binary package hint: monodevelop-python

I'm so sorry for this summary but ... i cannot be more precise. I've installed everything about python but...

It's unable to open any .py file inside a Python project, even the main.py automatically created:
A window is displayed indicating :
Le fichier <blabla> main.py n'a pas pu être ouvert.
Argument cannot be null.
Parameter name: runtime.

It's also unable to open the prject options window:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.NullReferenceException: Object reference not set to an instance of an object

The python language support for monodevelop does not yet include support for python 2.7. You currently have to have python 2.6 or 2.5 installed to use it.

[Charles Dumont (unomadh)]

You know current is 3.2 ?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jimmy Merrild Krag (beruic)]

It worked for me to install python2.6.
Could you at least add a dependency to the package as a quick-fix, and maybe give some hint to which version is used in MonoDevelop?

[Charles Dumont (unomadh)]

This works today having python 2.7 or 2.6

The problem is that these are not dependencies of the plugin. I couldn't imagine at the moment that I had to install a previous version, I just thought I had to have the latest version installed...

Of course, i really would love to see python 3.2 work on Monodevelop (I continue to hope)

I would also appreciate that the last version is the one selected by default

[Jimmy Merrild Krag (beruic)]

How did you make it work with 2.7? I did have 2.7 installed, but had to install 2.6 to make it work.

[Charles Dumont (unomadh)]

Maybe by choosing the version in the project options

[Jimmy Merrild Krag (beruic)]

Nice. Then I can uninstall 2.6. Would whish 2.7 was default when I create the project though.
