Scrapy failing in terminal - python

pkg_resources.DistributionNotFound: Scrapy==0.24.4
I have been struggling for hours, I had different errors before, but I deleted all references to python 2.7 in my PATH, (probably a mistake), and now I'm getting new errors.
Help would be greatly appreciated on how to get Scrapy working on my mac.

This error says that the Scrapy Distribution that you are searching for can not be found. Try to upgrade your Scrapy by:
easy_install --upgrade scrapy
or:
pip install --upgrade scrapy

Run scrapy under windows 7

I want to create a new scrappy project under win 7. I have installed scrapy over pip and everthing went find.
I am using pip 1.0.1 from c:\python27\lib\site-packages (python 2.7).

Django - ResolutionError and DistributionError

I had to uninstall my django==1.6.4 and install 1.5 for a project, but now when I install 1.6.4 with pip and try to start a project with django-admin.py startproject PN I get
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/2.7/bin/django-admin.py", line 5, in <module>
pkg_resources.run_script('Django==1.6.4', 'django-admin.py')

pkg_resources.ResolutionError: No script named 'django-admin.py'
martinssmacbook:bin martinspasov$ pip install django==1.6.4
I tried installing 1.6.5 but then when I try to start a project i get
Traceback (most recent call last):

File "/Library/Python/2.7/site-packages/pkg_resources.py", line 639, in resolve
raise DistributionNotFound(req)
pkg_resources.DistributionNotFound: Django==1.6.4
Any ideas onwhat to do ?
this is because you should delete all 1.6.4 files and then install 1.6.5.
but now there are also 1.6.4 files in your Linux / windows.
in windows,
you should delete the files in python/lib/site-packages/django
to uninstall the main Django files.
nd then delete Django-VERSION-py2.7.egg or fix the VERSION in
it. not just these.
you have to delete following 4 files:
django-admin.exe, django-admin.py,django-admin.exe.manifest,django-admin-script.py
then you can reinstall the django.
(In fact, if you know the file, you can try to edit it with change the version.)
in Linux, you can do like that.
if there 's something wrong, you can try to delete all.

Having troubles with pip command

I am using Mac 10.8.5. I cloned a repository from GitHub on my local system and went into it's directory using terminal. Then I ran the following command:
fab setup
I got the following error:
Traceback (most recent call last):
File "/usr/local/bin/fab", line 5, in <module>
from pkg_resources import load_entry_point
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>
working_set.require(__requires__)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require
needed = self.resolve(parse_requirements(requirements))
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve
raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: paramiko>=1.10
So after this, I googled the error and saw the following article:
http://kitnew.com/pkg-resources-distributionnotfound-paramiko.html
I performed the operations that were mentioned in there and when I ran the command 'fab setup', I again got the same error message. Can somebody tell me what I am missing or what thing is going wrong?
Note: I am using all these technologies including Mac for the very first time.

Bpython not working after upgrading to Mavericks

I'm receiving the following error when trying to open bpython in my terminal and I'm not sure how to fix it. I'm new to Python and so I think I may not understand the package system correctly. I'm not sure if there is a conflict from having easy_install and pip both installed.
Traceback (most recent call last):
File "/usr/local/bin/bpython", line 5, in <module>
from pkg_resources import load_entry_point
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>
working_set.require(__requires__)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 666, in require
needed = self.resolve(parse_requirements(requirements))
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 565, in resolve
raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: bpython==0.12
Hah, I think I can answer this. When we released the last version of bpython I got confused in the PyPi web interface and accidentally removed the 0.12 tarball from the index replacing it with 0.13.
Your requirement was to have exactly bpython==0.12 fetched from the index which was sadly not there (it has been corrected by now).
