I'm using a server for which I am not root, and I have several scripts requiring Python 3.4.1. I built the software from the source tarball using the following syntax
$ ./configure --prefix=$HOME
$ make
$ make install
The software installed successfully, as I was able to launch python3 after modifying my .bash_profile to look in $HOME/bin. However, Pip was not so lucky.
$ pip3.4
Traceback (most recent call last):
File "/home/scnorton/bin/pip3.4", line 7, in <module>
from pip import main
ImportError: cannot import name 'main'
When I tried to run python3 get-pip.py, I get the following error:
Traceback (most recent call last):
File "get-pip.py", line 17474, in <module>

File "get-pip.py", line 17466, in main

File "get-pip.py", line 17406, in bootstrap
import pip
zipimport.ZipImportError: can't decompress data; zlib not available
I have checked the /usr/lib64 directory and concluded that zlib is installed on the server. I even executed the command module load zlib-1.2.8-1 and tried reinstalling pip again, with no luck. Could the problem be that Python3.4.1 is installed as a 32-bit application? If so, where can I go to get 64-bit Python3.4.1 for Linux?

If I want to debug the setup.py file of my package packagename getting installed via "pip install packagename" , is there a way to do so? I have tried downloading the source, adding set_trace() in setup.py and run:
pip install .
However, as soon I get pdb() prompt, the install fails with error:

Although I can debug the source via: python setup.py build, the behavior that I want to debug is applicable when installed through pip.
Pip is a python program. You can see it's content with cat $(which pip). Then you can copy it to a new file in your project's directory. For example, here is how it looks like for me:
File mypip.py:
#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal.cli.main import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw|\.exe)?$', '', sys.argv[0])
sys.exit(main())
Then you can add a breakpoint with pdb or use PyCharm as mentioned in the answer from Igor Yudnikov.
For reference, this is how it to looks like in my Pycharm
Oh! Just found a solution, its pretty easy. What is pip? It's a plain python file, which is I think somehow bound to run via python, and under the hood system makes something like
python pip install ...
so, at first we need to know where is pip
which pip
says
/Users/me/PycharmProjects/etlscripts/venv/bin/pip
So, we may go to Pycharm, create config like
then you'll be able to catch your exception. Cheers.
Good morning!
Until yesterday I was using python 2.7 and using the following code for writing output files for my scripts:
import sys
reload(sys)
sys.setdefaultencoding('utf-8')
But now I'm upgrading my code to python 3.7, so now I need to use importlib.reloadinstead of just reload. However, typing sudo -H pip3 install importlib on my shell gives me the following error:

Many thanks in advance!
importlib at PyPI is an outdated package intended for very old Python versions. For new versions of Python importlib is a module from the standard library, you don't need to install it, it's always available.
I am trying to run this example on MacOS High Sierra. It requires installing the page package, which requires installing the pytodos package, which requires installing the enum package, installation of which fails.

Note that I've tried to do the same on Ubuntu. And I had to repeat every step. However, installation of enum failed with this error instead:

What am I doing wrong?
You went wrong at pip install page.
You were supposed to provide your own module page.py, as described here.
pip install page pulled in some garbage and unrelated/unmaintained projects from PyPI.

Do I need to install Enum? Is there a version of Enum I need?
Sorry, I must have foobarred the last package I created.
Do a
pip install enum34
first.
Hello I am trying to install python-twitter and one of the dependencies HTTPLIB2 is giving me a lot of problems. I have searched the internet up and down but maybe I do not know what the right key words are. Here is the problem.
I am installing python-twitter. I install the requirements either by "pip install -r requirements.txt" or doing them one by one through for example "pip install httplib2". Then I run "python setup.py install". It's happy but then "python setup.py test" fails as followed with an error on import HTTPLIB2.

But I thought the print error was an incompatibility between python 2 and 3. Why am I getting this while I clearly have python 2.7 (I checked and uninstalled and reinstalled HTTPLIB2).
Thanks much for your help
i had a same issue. It seems to be python2.7 and 3.x version conflict issue and resolved by
python2.7 -m pip install -t lib/ -r requirements.txt
Just in case, this happens when you install httplib2 with a python3 version of pip and then execute it with python2.
This happens for example when creating manually an environment with:
pip install -t lib/ -r requirements
As it happens when creating an AppEngine standard environment vendor folder.
This happens because contrary to most of the libraries, httplib2 has completely different versions for python2 and python3.
