Failture installing PyGreSQL with pip [duplicate] - python

Python 3: ImportError "No Module named Setuptools"
(22 answers)
Closed 7 years ago.
I am currently trying to install PyGreSQL using pip install PyGreSQL, however, when I run the command I get the following error:
Could not import setuptools which is required to install from a source distribution.
Traceback (most recent call last):
File "/usr/local/lib/python2.7/site-packages/pip/req/req_install.py", line 375, in setup_py
import setuptools # noqa
File "/usr/local/lib/python2.7/site-packages/setuptools/__init__.py", line 11, in <module>
from setuptools.extern.six.moves import filterfalse, map
File "/usr/local/lib/python2.7/site-packages/setuptools/setuptools/__init__.py", line 12, in <module>
from setuptools.extension import Extension
File "/usr/local/lib/python2.7/site-packages/setuptools/extension.py", line 8, in <module>
from setuptools.extern.six.moves import map
ImportError: No module named extern.six.moves
Does anyone know what might be wrong? From what i can tell, something is wrong with extern.six.moves, however, I couldn't find anything about this online...

This ended up being due to the setuptools not being correctly installed on my machine. Thanks #Famarri for helping me realize that

ModuleNotFoundError: No module named '_brotli' when trying to install dash

I can't figure it out what is the problem. I use python 3.7. I saw on the internet a similar issue on windows, but not on mac. I would be really grateful if you could help me.
You seem to have a broken installation of the brotli module (missing its native code component _brotli).
Try uninstalling it with pip uninstall brotli, then reinstall it; pip install brotli.
Going forward, I would heavily recommend you learn and use virtualenvs instead of installing everything into your Python's site-packages.
After uninstalling and installing again brotli it worked! Moreover, working in virtual environments is really more appropriate. Thank you a lot, AKX.

Checking Ansible version(ansible --version) but getting following error

And Jinja2 modules Requirement already satisfied
Traceback (most recent call last):
File "/usr/bin/ansible", line 60, in <module>
import ansible.constants as C
File "/usr/lib/python3.7/site-packages/ansible/constants.py", line 12, in <module>
from jinja2 import Template
ModuleNotFoundError: No module named 'jinja2'
This looks like a broken install. A dependency is missing. Try:
pip3 install jinja2
This is not really supposed to happen when you install ansible "normally". If the above does not fix your problem, I suggest you reinstall ansible from scratch on your system

"No module named zlib" error anytime I use pip

I'm using terminal on mac, and anytime I attempt to use pip, I get the following error message telling me that it cannot find a module named zlib:

import zlib
ModuleNotFoundError: No module named 'zlib'
I've read several SO posts with the same error message, and have tried their solutions, including attempting to install zlib using homebrew, which fails, and updating my Xcode developer tools. I also installed pip earlier using python get-pip.py, and it said it installed successfully.
The reason I need pip is to install a package for use on python 2.7, but doing $ pip install "package-name" produces the same error as above. I have both Python 2 and 3 installed on my machine, if that helps. I'm kind of new to pip and using the command line in general, and I'm super confused; if anyone could help me out I'd really appreciate it.
This is the OP. I was able to fix the issue, and wanted to post my solution here in case it would help others.
Essentially I believe it occurred because Python2 is default on my machine, but pip is by default pointing to resources pertaining to Python3, or something like that. Doing pip2 --version instead provided the expected response.

ImportError: No module named pydispatch
I have attempted searching on google for the chance that this tutorial may be broken or something, but I don't believe it is. I have pydispatch and have attempted to install it using easy_install yet nothing changes. Can someone please help me with this? I know the code is completely correct as after a while I copied and pasted everything to ensure that it wasn't my syntax.
The instructions (apparently incorrectly) say to install pydispatcher. I had the same problem you did until I installed the module PyDispatcher. Confusingly, both exist.
To clarify on #Phil's answer.
I saw:
No module named pydispatch
And so I did:
sudo pip install pydispatch
The install worked, but Scrapy still didn't work because we were supposed to:
sudo pip install pydispatcher
You need to install PyDispatcher separately. Please take a look at the required packages for the tutorial to work along with the installation instructions here:
PyOpenGL Introduction
Check particularly within the section named Package Installation

I'm getting an error because the ssl module isn't available
If I run help('modules') from the python interpreter it is listed there
When I try to import it from the interpreter, I get

Ensure that you have openssl package installed.
