Error While Starting New Scrapy Project

I have installed Scrapy using Ubuntu packages provided in the Scrapy website. But on starting a Scrapy project scrapy startproject test I am getting error message as. Tracebac

Solution 1:

According to the error:

pkg_resources.ContextualVersionConflict: (pyasn1 0.1.7 (/usr/lib/python2.7/dist-packages),
Requirement.parse('pyasn1>=0.1.8'), set(['pyasn1-modules']))

The required pyasn1 version should be greater or equal to 0.1.8 and you currently have installed in your global py2.7 dist-packages v0.1.7.

sudo pip install pyasn1 --upgrade will update your current pyasn1 package to the latest version and should solve the problem.

Note: you may wish to check that other projects or applications you have that depend on this library are still functioning correctly.

As a solution to the above notice, please have a look at creating virtualenv's for your python project as this will isolate dependant packages to your project (global ones remain unaffected). more information on virtualenv can be found HERE

Solution 2:

first you should visit https://pypi.python.org/pypi/pyasn1/ then download pyasn1-0.1.9-py2.7.egg (md5) and then execute easy_install pyasn1-0.1.9-py2.7.egg it works on my computer (CentOS 7)

Solution 3:

i just had exactly the same problem. it's something with not updated dependencies. try something like this:

sudo apt-get autoremove python

then:

apt-get install python

apt-get install python-scrapy
