Unable to do heroku's Python tutorial within D

Question

EDIT2: OK this is weird. (I can't answer my own question, so I just put it as another edit to the question. I think it has something to do with the fact that I tried to do this installation within a Dropbox-synced directory. I got this to work on my Desktop. Can anyone explain why this is the case?

Original question:

I'm trying to do Heroku's Python setup tutorial (http://devcenter.heroku.com/articles/python), on my Mac OS X (Lion), but I get caught up with the step of creating a virtualenv.

So what I did was this in the command line (not using sudo caused permissions error):

sudo pip install virtualenv

But then, when I do "virtualenv venv --distribute" (I also tried with sudo), I get the following error:

New python executable in venv/bin/python
Installing distribute..............................................................................................................................................................................................................................................................................................done.
Installing pip...
  Error [Errno 2] No such file or directory while executing command /Users/AndyFang/Drop...env/bin/easy_install /Library/Python/2.7/...pport/pip-1.1.tar.gz
...Installing pip...done.
Traceback (most recent call last):
  File "/usr/local/bin/virtualenv", line 8, in <module>
    load_entry_point('virtualenv==1.7.1.2', 'console_scripts', 'virtualenv')()

    raise child_exception
OSError: [Errno 2] No such file or directory

Not really sure what to do. It seemed like I didn't have easy_install on my Mac, but I do have it... I'm not sure what the deal is?

EDIT: I also just tried installing virtualenv with easy_install, but I get the exact same error.

Answer 1

If your problem is the same as mine, then it's because there's a space somewhere in the path to your Dropbox-synced folder.

Answer 2

Virtualenvs aren't portable, so you can't keep them synced across multiple machines if the paths don't match up.

In general, it's a bad idea :)
