pypi 0.4.3: "#!/usr/bin/env python3" gets changed to "#!/bin/python" on install

[ghost]

Thanks for pushing the update to pypi, However I encounter the following problem:

When I run greg I'll see the following:

bash: /usr/local/bin/greg: /bin/python3: bad interpreter: No such file or directory

[manolomartinez]

Huh. I'm not seeing any problems here. You install by running pip install greg, don't you? What happens next?

[Narrat]

I would ask additionally for:
What distro?
Got /bin and /usr/bin merged?
What result for "whereis python3?

At least the bad interpreter error looks like /bin and /usr/bin are separate things

[manolomartinez]

Yep, what Narrat said :)

[ghost]

Oops sorry. Yes, installed via pip install greg and I encounter the problems in first post: #29 (comment)

However, if I fully remove greg and then install from here on git, it works just fine!

• Ubuntu 14.04 with both python2.7 and python3
• How do I determine if /bin and /usr/bin are merged? (I don't think they are...)
• result for whereis python3:

python3: /usr/bin/python3.4-config /usr/bin/python3.4m-config /usr/bin/python3.4 /usr/bin/python3 /usr/bin/python3.4m /etc/python3.4 /etc/python3 /usr/lib/python3.4 /usr/lib/python3 /usr/bin/X11/python3.4-config /usr/bin/X11/python3.4m-config /usr/bin/X11/python3.4 /usr/bin/X11/python3 /usr/bin/X11/python3.4m /usr/local/lib/python3.4 /usr/include/python3.4 /usr/include/python3.4m /usr/share/python3 /usr/share/man/man1/python3.1.gz

If I install using python2.7 with pip2 install greg then I get this error:

File "/usr/local/bin/greg", line 2
SyntaxError: Non-ASCII character '\xc3' in file /usr/local/bin/greg on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

So then if I edit /usr/local/bin/greg to change first line to #!/usr/bin/python3 it then gives me this error

Traceback (most recent call last):
  File "/usr/local/bin/greg", line 17, in <module>
    from greg.gregparser import main 
ImportError: No module named 'greg'

[Narrat]

How do I determine if /bin and /usr/bin are merged? (I don't think they are...)

If /bin is a link to /usr/bin for example

One point of notice. iirc greg doesn't run under python2 (hence the encoding issue). Changing in the python2 environment the interpreter to py3 causes the problem, that it searches for the py3 module and cannot find it.

If running the correctly py3 pip version producing the error for file not found. hm
Wonderous why the /usr/bin/env check returns the wrong path, as your python3 interpreter is installed in /usr/bin (and if /bin isn't a link to /usr/bin this will fail).
Something is setting the wrong env (or at least looks like that)
You could see what happens if you change

#!/usr/bin/env python3

to

#!/usr/bin/python3

Ok, my /bin and /usr/bin are separate directory.

I just did a fresh install of greg from pypi using pip install greg again receive the following error upon run: bash: /usr/local/bin/greg: /bin/python: bad interpreter: No such file or directory

So I looked in the file of /usr/local/bin/greg and see on first line: #!/bin/python and NOT #!/usr/bin/env python3 If I change it back to #!/usr/bin/env python3 or even #!/usr/bin/python3 everythign works fine!!

So this is a problem because I do not have /bin/python at all on my Ubuntu. So why on installation does that first line get changed to #!/bin/python ???

Ok when I do a build from git using pip install git+https://github.com/manolomartinez/greg the shebang line in /usr/local/bin/greg is set correctly to #!/usr/bin/python3 but when I install 0.4.3 from pypi the shebang is set to #!/bin/python - super odd, I have no idea why.

I think setuptools or distutils might be mangling the shebang line?

I wonder if my environment is messed up somehow. At any rate I'll stay with the git build for now instead of using pypi.

[manolomartinez]

Thanks for the report, I will try to understand what's going on and get back to you.

[manolomartinez]

All right, I've uploaded a test package to testpypi in which I only use setuptools. If you can, please install it with

pip install --index-url https://testpypi.python.org/pypi/ greg

and let me know if this behaves.

[ghost]

Yes! That works well for me, it installs correctly, and launches correctly. And the shebang of /usr/local/bin/greg is set correctly to #!/usr/bin/python3

Thanks again for making greg and for fixing the problems as they come up!!

Is there anything you need from me to help close this issue or help push the test version live?

Thanks again.

Nudging me from time to time works fine ;)
Done!

Awesome, thanks again! I updated and everything is working well.
