I have (as far as I can tell) installed all the dependencies for Scrapy correctly. I am running the Scrapy.org, 64 bit version of Python on Windows Vista 64 bit. I have so far installed:
- Visual C++ Redistributables (64 bit)
- Win32 Open SSL (with the DLL's copied to bin directory -as per the instructions above)
- Environment variables added for C:\Python27, C:\Python27\Scripts and openssl-win32\bin
- Visual C++ Studio 2008
- Pywin32
- Zope
- Twisted
- lxml
- PyopenSSL
- w3lib
Is this a complete list of what I need to make Scrapy run correctly? So far, when I try running the command:
scrapy startproject myproject
I get the following error in Command Shell:

Can anyone see what is causing these errors? I'm fairly new to Python and Scrapy is by far the hardest thing I have tried so far to get working.
Thanks
