Raspberry Pi - Errors downloading Python Modules - python

I am trying to download a module for python on my raspberry pi 3. The first error I received was saying my urllib3 was not up to date. This error was given whenever I ran the pip command. So I re-installed urllib3, and it downloaded the same version I had, even though I had just ran sudo apt-get update. I then decided to remove pip, and re-install, and that didn't fix it. The final thing I have tried doing it manually downloading urllib3 from github, and then installing it onto my pi using setup.py. This was successful in eliminating the previous error, but I am now receiving this.
$ pip install imutils

I would really appreciate any help, thanks.

Getting error while installing scrapy in ubuntu

I want to install scrapy for my project in ubunu. i used pip to install scrapy but i always getting this error while installing.

if _lib.Cryptography_HAS_SSL_ST:

so how do i get rid of this error and install scrapy
This happened to me (although with Anaconda, not pip).
I tracked it down to updating pyopenssl from 16.0 to 16.2.
My solution was to first reinstall Anaconda (which reverted pyopenssl to 16.0). (You may not need to do this.)
After that, I just ran
sudo apt install python3-openssl
After doing this, my problem seemed to be corrected.
I think you should update your pip first, then try again.
I see pip==1.5.6, omg, it's older than the moon

Cannot install PIP on Raspbian

I can't get PIP running in my Raspberry (running in Wheezy).
After I always got this message:

Any ideas what I'm missing?
Thanks for your help.
OK, sorted.
Apparently my Python 2.7 install was somewhat corrupted.
After I did sudo apt-get -u dist-upgrade which - with some hick-ups - fixed the install.
After that I re-built the 3.5.1 binaries and pip3 works now fine.

pip install error: cannot import name 'unpack_url'

I'm using Python 3.4.1 64-bit on a Windows 8.1 machine. Pip has been giving me problems lately, specifically this error:

This occurs every time I try to install any package. Has anyone had this problem before?
I used: easy_install -U pip
problem solved
Well, obviously there is an error with pip and unpack_url is probably use to download packages from PyPi. I suggest reinstalling by executing this script.

Failed install after installing Myysql-python

Problem using MySQLdb after installing MySQLdb-python. I followed the instructions I followed the instruction that had me delete the build and delete the egg then modify the my_config and then run the install again. I also tried installing the 64 bit version still no luck

Problem solved, it was problem with Aptana not picking up the new library.

Python trouble with nose

I am having some trouble with LPTHW on Exercise 46 in which we create a skeleton directory for a future project and install pip among other things. I have having a problem with nosetests. Whenever I run it I get a problem. I have everything set up as he wants me to.
Here is the problem (I am running Ubuntu 12.04)
Traceback (most recent call last):
File "/usr/local/bin/nosetests", line 9, in <module>

I figured it out. When I installed Nose the first time, I didn't 'sudo' it and it never installed. And I cicked out of terminal before I saw it. At least. that's what I thought happened. I deleted nose and reinstalled it and now it works.
Suddenly get the same error. I fix this by removing --with-id from the argument.
I used it previously.
It works now.
