Launching Python has encounterd a. Unable to get project for the run

Question

Launching Python has encounterd a problem. Unable to get project for the run

It would let me put the word problem in the title.

The title is the exact message i get when i try to run/debug a file in Aptana 3.

I have always been able to run Python in Eclipse without problems. Does anyone know what causes this error?

For testing purposes i just created a new Pydev project with only 1 file in it.

Have you recently changed your interpreter settings? Try creating a new run configuration. – Gonna

I am also facing same issue, please help me if you resolve this issue please. – Springs

I created a new "Python Run" in the setting of "Debug Configurations" for testing at yesterday, and forgot to remove it, so when I make an new Python file and runing with it using this new-run at default. After I remove this python-run, everything is OK again. So, I advice you to check your "Python Run" in the setting of "Debug Configurations", for making sure which python-run you are using now. – Crutch

Answer 1

I had the same problem with Aptana and just solved it. In my case I had configured another interpreter (IronPython) for running another script. When I got back to a previous script I got the same error message as you "Unable to get project for the run" because it was trying to run it with IronPython instead of Python.

I would therefore recommand the following:

1) Check your interpreter configuration. -> Window -> Preferences -> Pydev -> Interpreter Python

If you have no interpreter there try autoconfig. If it doesn't work you will have to browse it yourself by clicking New (then it should be somewhere like C:\Python27\python.exe)

2) If you have an interpreter, it means that Aptana is trying to run your script with another interpreter. In that case right click on your script file in Aptana -> Run as -> Python run.

That worked for me.

Good luck !

It occurs when you create a New configuration for run a program. go to Run > run configuration > python run

select "New configuration"

press on delete icon

and again Run the program .

Answer 4

I had similar issue. Below action solved my problem.

Go to Run > run configuration > python run Delete all the configurations below python run - it may not be a great option if you have any custom configuration settings.
