So I'm trying to install Scrapy on Lion and am not sure if it's properly installed or not.
I followed the guide here http://doc.scrapy.org/en/latest/intro/install.html#intro-install
Then tried to do the first step to create a tutorial project here,
http://doc.scrapy.org/en/latest/intro/tutorial.html
But when I try to run,
scrapy startproject tutorial
It doesn't work. I get...
$ python scrapy /Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'scrapy': [Errno 2] No such file or directory
Any idea why I get such an error?
Well turns out it's likely a path issue.
On my Mac, I used easy_install from /usr/bin.
sudo /usr/bin/easy_install scrapy
The resulting scrapy command is then installed into /usr/local/bin/scrapy.
You might not have that directory in your path, so see if that's true with:
echo $PATH
If it isn't in there, you can temporarily add it like export PATH=/usr/local/bin:$PATH, or modify your ~/.bash_profile to add it permanently.
Alternatively, I typically don't use the system installed Python in Mac - I install homebrew and install a separate version of Python, and install scrapy with that version (scrapy is then installed into /usr/local/share/python/scrapy).
