ubuntu with both Python 2.7 and 3.4

[Malik Rumi]

1. I used the ubuntu package to install and all seems to have gone well with that. However, when I follow the tutorial to run scrapy startproject tutorial, I got /usr/local/bin/scrapy no such file or directory. Then I ran /usr/bin/scrapy and it was fine. So for the time being I have to run that everywhere I should be able to just run 'scrapy'. I can live with this, but if there is a way to get this to install to the 'right' place and save me a few keystrokes without messing things up, i'd like to know about them.

2. When calling scrapy shell, the tutorial docs say it should open in ipython. I do have ipython, but it is attached to Python 3.4. When I ran /usr/bin/scrapy shell, I got a regular interpreter. Since the rest of scrapy seems to be working ok, I assumed the dependencies resolved by the ubuntu packages included binding it to 2.7. If so, what is the best way to access ipython through the scrapy shell, again, without messing up anything working i have already?

3. I was surprised that there was no reference to using a virtualenv in the docs. Do people not use scrapy that way?

thanks

I'd recommend installing using pip, instead of the ubuntu packages.
That works better with a virtual environment. To run scrapy in a
venv, just setup the venv and install scrapy, ipython, and all
dependencies. This should solve all your questions.

Thanks. Travis. Is there a requirements.txt somewhere, or should I just put one together based on the terminal output from installing ubuntu packages? Pip does not automatically install dependencies, for some reason...

turns out pip *does* install dependencies, maybe your pip is outdated.
within your virtualenv you can start with a `pip install --upgrade pip`
from there, you can install scrapy.

pip is up to date. Maybe it was because I installed it to 3.4?
