Does pyspider Work with Windows?

Yes, it should, some users have made it work on Windows. But as I don't have windows development environment, I cannot test. Only some tips for users who want to use pyspider on Windows:

  • Some package needs binary libs (e.g. pycurl, lxml), that maybe you cannot install it from pip, Windowns binaries packages could be found in http://www.lfd.uci.edu/~gohlke/pythonlibs/.
  • Make a clean environment with virtualenv
  • Try 32bit version of Python, especially your are facing crash issue.
  • Avoid using Python 3.4.1 (#194, #217)

How to Use WebDAV Mode?

Mount http://hostname/dav/ to your filesystem, edit or create scripts with your favourite editor.

OSX: mount_webdav http://hostname/dav/ /Volumes/dav
Linux: Install davfs2, mount.davfs http://hostname/dav/ /mnt/dav
