Bottle doesn't work under a relocatable virtualenv

[pvicente]

On heroku platform virtualenvs are relocatable (--relocatable parameter) and it add an activation line at the top of bottle.py file and the import line from __future__ import with_statement dumps an exception like it:

Exception

  File "/private/tmp/venv/bin/bottle.py", line 19
    from __future__ import with_statement
SyntaxError: from __future__ imports must occur at the beginning of the file

Steps to reproduce this problem

1. virtualenv --distribute venv
2. source venv/bin/activate
3. pip install bottle==0.10.11
4. virtualenv --relocatable venv/
5. bottle.py 

Original File bottle.py

Um, how am I supposed to fix this? Is there a virtualenv issue for this?

You are right

1.8 (2012-09-01)

Fix --relocatable when a script uses future imports. Thanks Branden Rolston.

It has been fixed recently.

I will open an issue on Heroku Platform they are using virtualenv 1.7.2
