I am new to python and am having trouble getting the python requests package to run. I have searched around for answers, but it seems that the question is most often answered with instructions on installing the requests package, which you will see I have already done.
Before I start, my specs are as follows:
OS: MacOSX Catalina 10.15.7
Shell: iTerm2 Build 3.3.12
Python Versions:
System: 2.7.16
pyenv: 3.9.0
Use Case: I am experimenting with web scraping and am attempting to write a simple program that will scrape some data from a local car dealership's website (e.g. scrape info on cars listed under $20k).
Before starting the project, I installed the requests package with the following command:
% pip3 install requests
I then opened up a vim file and wrote the following, just to ensure that the requests package was working properly:
import requests
URL = 'cardealerurl.com/query'
page = requests.get(URL)
I saved the file as carScrape.py.
Then I went beck to the shell and executed the following:
python carScrape.py
on execution, I receive the following error message:
Traceback (most recent call last):
File "carScrape.py", line 1, in <module>
import packages.requests
ImportError: No module named packages.requests
Any help with this would be greatly appreciated. If more information is needed, please just let me know and I will provide whatever I can. Thank you all so much.
I was able to solve this by running the following commands:
% sudo -H pip3 uninstall pip
% python3 -m ensurepip
% pip3 install requests
This was after a pretty long chunk of time trying other solutions that did not work. I also had to start a new shell to get rid of the error message.

Hi I'm a Python newbie trying to program python using pymesh library but I cant get it to install properly.
Accordijng to attached image I have installed it, and the package says its for 3.8.x and I have python 3.8.2 installed.
pymesh installation instructions (https://pymesh.readthedocs.io/en/latest/installation.html) say to run a test after installing the package. The test fails.
(work) (base) D:\Downloads\HoleCutter>python -c "import pymesh; pymesh.test()"
Traceback (most recent call last):
File "<string>", line 1, in <module>
AttributeError: module 'pymesh' has no attribute 'test'
I dont have the resources/capability to 'build packages with cmake'
screen snap from command prompt window
The reason is the PyMesh library isn't kept up to date on PIP, instead you have to use Docker or compile it yourself. This problem is covered by the following issue on Github, however no action has been taken for years: https://github.com/PyMesh/PyMesh/issues/94
Have you tried "pip install pymesh" or "pipx.x install pymesh"?
I think the instructions in the link you provided are for Linux and Mac OS. You can look at this link: ImportError: No module named PyMesh
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.
I have recently started using Python and have installed version 3.7.3 on my Windows 10 machine running as administrator. I then ran the following command in a command prompt to install the xmpppy package
python -m pip install xmpppy
Next I created the following base.py file that uses the aforementioned xmpppy package
#!/usr/bin/env python
import xmpp
user="user"
password="pword"
server="server"
jid = xmpp.JID(user)
connection = xmpp.Client(server,debug=[])
connection.connect()
result = connection.auth(jid.getNode(), password,"LFY-client")
connection.sendInitPresence()
while connection.Process(1):
pass
Now when I run the command
python base.py
in the folder that the base.py file exists I get the following error message:
Traceback (most recent call last):
File "base.py", line 3, in <module>
import xmpp
File "C:\Users\AGO109\AppData\Local\Programs\Python\Python37\lib\site-packages\xmpp\__init__.py", line 29, in <module>
import simplexml,protocol,debug,auth,transports,roster,dispatcher,features,browser,filetransfer,commands
ModuleNotFoundError: No module named 'simplexml'
In the folder C:\Users\AGO109\AppData\Local\Programs\Python\Python37\lib\site-packages\xmpp simplexml.py, protocol.py etc. all exist and the windows system variables contain the paths for python and packages, so what's the problem?
I'm facing same issue.
Try installing each of the packages using command like pip install simplexml and then run your code. Mine is stuck at installing transports.
Alternately,you may try switching to using sleekxmpp that comes bundled with your python installation. As sleekxmpp has latest version published in 2017 compared to that of 2006 for xmpppy, i'm planning to stick with using sleekxmpp library. If you update your code to use sleekxmpp as per the boilerplate code at https://pypi.org/project/sleekxmpp/, XMPP connections work.
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.
So I had been working with virtualenvs a couple months ago but had to stop for a while and now I don't seem to be able to get it working again.
Here is what I did
D:\CS\Python_Projects\HomeCenter>venv\Scripts\activate
(venv) D:\CS\Python_Projects\HomeCenter>pip freeze
You are using pip version 6.0.8, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Flask==0.10.1
Flask-SQLAlchemy==2.0
itsdangerous==0.24
Jinja2==2.8
MarkupSafe==0.23
SQLAlchemy==1.0.8
waitress==0.8.9
Werkzeug==0.10.4
(venv) D:\CS\Python_Projects\HomeCenter>server.py
Traceback (most recent call last):
File "D:\CS\Python_Projects\HomeCenter\server.py", line 3, in <module>
from waitress import serve
ImportError: No module named 'waitress'
(venv) D:\CS\Python_Projects\HomeCenter>
Same happens if I were to run app.py, it won't find flask. I have been using PyCharm and when I check there it tells me the interpreter is pointing towards 3.4.2 virtualenv at D:\CS\Python_Projects\HomeCenter\venv
So why can't it find the modules?
Oh contents of server.py in case it's relevant
from waitress import serve
import os
from app import app
port = int(os.environ.get('PORT', 9999))
serve(app, host='0.0.0.0', port=port)
Hello I am korean student so I can't English not well. Please understand.
In my case, I have a well operated program but suddenly occured "not found" error like you after update mac os to BigSur.
but I finally found solution.
when before update I compiled by "source venv/fileName.py" but after update I compile by "python3 venv/fileName.py" then well operate
You try it too.
A couple of things could have happened here:
Use which python and which pip to check if both are from the virtual env itself.
As dirn suggested in the comments, it might be a PATH mixup. The packages were installed in the virtual environment but the script was executed from outside the environment interpreter. (Use venv\Scripts\python.exe <filename.py> instead of just filename to execute).
