I have tried many ways of installing psycopg2 after having installed PostgreSQL using the one-click installer, but anyway I try confronts me with the same import error in python: ImportError: dlopen(/Library/Python/2.5/site-packages/psycopg2/_psycopg.so, 2): Library not loaded: libpq.5.dylib
Referenced from: /Library/Python/2.5/site-packages/psycopg2/_psycopg.so
Reason: image not found
I am on Mac OS X 10.5.8. I am using Python 2.5. I installed PostgreSQL from the installer (I did not port it) and it installed in /Library). I added /Library/PostgreSQL/9.1/bin to the setup.cfg of the source psycopg2, as instructed in the INSTALL file and everywhere on the internet and then ran sudo python setup.py build and then sudo python setup.py install.
I also tried exporting /Library/PostgreSQL/9.1/bin to my path instead and running sudo pip install psycopg2. But the exact same problem occurred in all of these scenarii.
I would greatly appreciate some help with this.

The problem is that at runtime the libpq.5.dylib file can't be found because it is not in one of the default locations searched by the dynamic (runtime) linker. Try to define the environment variable DYLD_LIBRARY_PATH before launching python. I am no MacOS X expert but something like:
export DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.1/lib
will probably work.

I am following [these][1] instructions on setting up a macOS virtual environment. I have followed all the instructions but when I get to the last part where I have to reload the startup file by making the following call in the terminal:
source ~/.bash_profile
I get the error message:
/Applications/Xcode.app/Contents/Developer/usr/bin/python3: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')
virtualenvwrapper.sh: There was a problem running the initialization hooks.
If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is
set properly.
I have tried different solutions from the internet but I am unable to get a fix.
Running which python3 and which virtualenvwrapper.sh returns:
/opt/anaconda3/bin/python3
/usr/local/bin/virtualenvwrapper.sh
My initial thoughts are that this may be due to the fact that I am running both anaconda python and regular python on the same computer.

I have installed the latest version of IBM SPSS Statistics(Version 26) which has pre installed python 3.4 and 2.7. i am trying to use version 3.4 python. i am able to import modules like pip , sys , os etc. i tried pandas the same way. i am unable to do so. getting error no module found. Hence going through our forum and IBM support did the following changes.
received the following error
1) tried pointing the site-packages via
import sys
# Assuming windows and standard python folder here.
sys.path.append(r"D:\Python34\Lib\site-packages")
2) changed the path in the settings of SPSS
3) Tried installing pip in the below folder as suggested in the forum but got message i have already installed the updated version.
C:\Program Files\IBM\SPSS\Statistics\Subscription\Python3
4) following versions of python were installed
have tried what i could. Need your expertise help to fix the same which will help me to install/use modules needed for SPSS. Thanks.
This is going to be painful to explain, I'll do my best.
As far as I can tell, you're on windows. Usually when we need a new package, we just open cmd and type pip install xxx (assume you added python to path when installing it). The reason that this works, is because when you type pip install xxx in cmd, windows recognize pip to be a command because python path is in system variables. Windows know that I can execute pip install with this python path.
However for SPSS python (3.4), that python had a different path in the system. Thus when you only have the 3.7 or 3.8 python in path, windows cannot install package to you 3.4 python, and I'm not sure if you can have more than one python path in system.
In order to fix this, you need to first figure out what's the path to your 3.4 python, then in this page you can follow the instruction to remove your 3.7 or 3.8 python in path, and add your 3.4 path, then you can do pip install xxxx for whatever package you want
I did the same thing with a arcgis python distribution, hope this works for you. If the attached page does not work, just google add python path to windows and look for a instruction that works on you PC
Oh and the reason that you can import pip, sys and some other package but not pandas, is because python is 'battery included', it comes with tons of packages pre-installed for additional functionality, but pandas is not one of them.
Fixed it since my ananconda had version 3.7 .i created virtual environment and installed 2.7 python with anaconda package. Pointed SPSS to the 2.7 folder and was able to import pandas.
Tried to run a script I wrote yesterday again today and ran into this:
ImportError: cannot import name 'Repo' from 'git' (/usr/local/lib/python3.7/site-packages/git/__init__.py)
I am at a complete loss. On a new computer so the only thing different install wise would have been that I installed pycharm. I am currently trying to run through bash shell on a mac. The exact code was running as excepted earlier, no code changes.
Things I have tried:
uninstalling/reinstalling python
uninstalling/reinstalling pip
uninstalling/reinstalling gitpython
Running on:
mac catalina
python version 3.7.6
pip version 20.0.1
As a side note, the script works as intended until the automated git push. Wondering if I should just make the os calls myself and not worry about this?
I really dont understand what I did/am doing wrong here.
EDIT:
Again, sorry as this is my first mac computer. I did a brew uninstall of python3 and reinstalled through the app store to 3.8.
ImportError: cannot import name 'is_cygwin_git' from partially initialized module 'git.util' (most likely due to a circular import) (/Library/Frameworks/Python.framework/
I know cygwin is for windows, but I figured I'd play along and trying a pip install pycygwin.
Install threw an error asking for cython, so I did another pip install and tried again. The pycygwin then complained gcc was missing so I did a brew install of gcc. With gcc installed and correctly on path, it still says it cant find it and exits with
build/cygwin/_cygwin.c:611:10: fatal error: 'sys/cygwin.h' file not found
#include <sys/cygwin.h>
^~~~~~~~~~~~~~
1 error generated.
error: command 'gcc' failed with exit status 1
Thinking I might just try a different package manager? Currently, an attempt to rerun the script yeilds
ImportError: cannot import name 'Repo' from partially initialized module 'git' (most likely due to a circular import)
To which I investigated but I shouldn't have any overlapping dependancies.
On the script throwing the error I'm using:
import csv
import yaml
import os
from git import Repo
and on the wrapper I made and imported, I'm using:
import subprocess
import re
Will update if I get any further on this, would love some suggestions.
EDIT:
Importing using just import git works throws a different error, like the python is trying to get itself?
ImportError: cannot import name '<file name>' from '<file name>'
If I change the file name and try to run it, it comes backs with:
ImportError: cannot import name '<old file name>' from '<old file name>'
***FIXED****
Uninstall of python through homebrew
Reinstall of python through mac app store
Uninstall/Reinstall of modules through pip
Saving the file under a new name and deleting the old one
Still have absolutely no idea why/how this happened but the above worked for me. If anyone knows why something like this can happen, I would love to know. Cheers.
While trying to run scrapy spider in docker-debian every time I get an error:
File "/usr/local/lib/python3.6/site-packages/scrapy/crawler.py", line 82, in
crawl
yield self.engine.open_spider(self.spider, start_requests)
builtins.ModuleNotFoundError: No module named '_sqlite3'
python version 3.6.3
scrapy 1.6.0
tried instruction from this post - ImportError: No module named '_sqlite3' in python3.3
still see this error.
when type sqlite3 command in terminal it shows sqlite3 version and start sqlite terminal.
SQLite version 3.16.2 2017-01-06
when type python and write next command in terminal:
import sqlite3
get this error:
ModuleNotFoundError: No module named '_sqlite3'
is there any way to solve this problem? looks like there is some misconfiguration but I can't find where it's
I have the same error with sqlite3 while I was trying to start my crawler using scrapy crawl my-crawler, after some searches and tried out different solutions, I found this answer useful to my error. Just remember that you need to download your specific python version, mine was 3.8.1 and it worked thanks to their answer. I have already install sqlite3 using sudo apt install libsqlite3-dev. Hope it works in your case, too. So, at first install it then reconfigure your python via instructions in the link.
I had same problem in centos, I just fix it. I install multiple python version in pyenv, so I switch the python version from 3.6 to 3.4.1, then problem solved.Maybe the problem was caused by pyenv,or it's python version's problem. If you don't have pyenv,maybe you need to reinstall python,or install a diffrent version of python.Hope be helpful.
Am trying to install utilities module for both python and anaconda environment.I have python 3 in my Mac.Here is the error I get.
pip install utilities
Could not find a version that satisfies the requirement utilities (from versions: )
No matching distribution found for utilities
Please help :(
If you are trying the ML example from here, then please copy the utilities.py from chapter 2 in your python 3 in Lib directory and you will be able to use the utility module.
Please try the below:
pip install data-utilities
You can find more on the Python Package Index - data-utilities website.
There is no module named utilities in Python,I believe you have encountered importing a file called utilities.py by the line import utilities. Showing the full source code might help. Additionally, check the gitgub repo of your source code for a file called utilities.py and copy it to your execution folder. If you are talking about python-utils, check this link.
Python Utilities contains many standard utility modules to solve common problems. They are :
File System -- os, os.path, shutil
Running External Processes -- commands
Exceptions
HTTP -- urllib and urlparse
Check This link
If this doesn't solve your issue, try installing the utilities-package using :
pip install utilities-package
