Why don't python scripts run unless I run them with explicit invocations of python?

Yes.

It's an app someone else wrote to manage Logitech unifying receivers in Linux. I downloaded it from some official-seeming site for open source software.

'Doesn't work' means that it behaves exactly as it did before.

I assume you mean #!/usr/bin/env python

Do this in your terminal and paste us the exact, unedited result, including both the "head" command and the prompt that you get following the output:

Code:

head -n 6 /usr/bin/solaar

BTW...

And what is the name of that site?

The current upstream version of solaar doesn't start with the same line that your first post indicated:

https://github.com/pwr/Solaar/blob/master/bin/solaar

Which makes me where you actually got it.

I got it from https://github.com/pwr/Solaar , the 'clone or download' button.

Do another clone or download, then reinstall. What you posted is not what you'd have if you acquired it like that today.

And:

Code:

#!/usr/bin/env /usr/bin/python

That's definitely wrong. Can I assume that the reason you never posted this until now, is because you only started trying it recently?

From now on, if you're going to edit the script to test stuff, make a copy and edit that.

This.

I just downloaded and used this, and (neglecting the unrelated dependency issues I had) there's no reason you should be getting the error you stated. If you download and try again and still get the same errors, please post the entire bin/solaar script in code tags.

I've never written a script in python, but I suspected I must have a
few from packages, and I do: asciidoc, a2x, viewer.py, explode.py.

They all don't work unless I run them with python. I suspect there's
a defect in my environment.

(interestingly, they marked it solved although it really isn't)
