Public bug reported:
I had a problem installing a node package with npm
tim@spiff:~$ npm install jsdom
Traceback (most recent call last):
File "/usr/bin/node-waf", line 6, in <module>
if os.environ.has_key('PREFIX_NODE'):
AttributeError: '_Environ' object has no attribute 'has_key'

It turns out that node-waf is a Python 2 script that ought to call
/usr/bin/python, but instead had a shebang line that searched the user's
environment for python. In my case, I had used pythonbrew to install
Python 3 locally
tim@spiff:~$ which python
/home/tim/.pythonbrew/pythons/Python-3.2.2/bin/python
This should have no effect on a system script in /usr/bin, but when a
script uses env that way, it has a profound effect. The fix is
simple...change the shebang line in /usr/bin/node-waf to call the
version of Python that it needs
sudo perl -pi.bak -e 's{#!/usr/bin/env python}{#!/usr/bin/python}'
/usr/bin/node-waf
This is the same issue as the one in
https://bugs.launchpad.net/ubuntu/+source/eyed3/+bug/307345
While /usr/bin/env is a wonderful thing and I often use it myself for
scripts in user space, it is really inappropriate for system scripts.
Perhaps it should be more difficult (impossible?) to create a package
that installs a script in /usr/bin with a shebang line that calls env
rather than the program that's actually required. I mean, why bother to
do all of that dependency checking if we're just going to fish around
for whatever version we can find each time the script is run?
