ImportError: cannot import name 'ParserError' from 'dateutil.parser' (/usr/lib/python3/dist-packages/dateutil/parser/__init__.py)
I tried reinstalling python-dateutil but this doesn't solve the issue. I am not very sure what has changed in my enviroment but pandas was working normally and one day it suddenly start showing this error. It will be great if someone can help me with this. Thanks!
from dateutil.parser import ParserError
You defined, or installed, a dateutil module.
And it isn't this one:
https://pypi.org/project/python-dateutil 2.8.2
Rename / reinstall so the import succeeds.

After installing pandas and some other dependencies, this error occurred when I ran my program.

I have tried upgrading the version of numpy and that printed out new different error saying numpy import error.

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed. This error can happen for
many reasons, often due to issues with your setup or how NumPy was
installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
* The Python version is: Python3.9 from "/usr/bin/python3"
* The NumPy version is: "1.22.4"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: libcblas.so.3: cannot open shared object file: No such file or directory
Anyone have Idea how to fix this?

How to fix it?
It looks like someone published a functools package on pypi, so if you had run:
# don't run this!
pip install functools
You may have accidentally installed that package. If you encounter this error, I would:
pip uninstall functools
To make sure that the functools you are using are the base package functools.
(I ended up here because I attempted to use functools.cache, which seems to only be present in Python 3.8, not earlier.)
I had the same error recently and it was because I had a file called functools.py in my project. Renaming it fixed the issue.
I've installed BSON library to convert strings to MongoDB ObjectIds, but when I try using the library, this comes up:

Also pip installs py3compat, but there's no 'binary_type' in there.
Any idea how to fix this?
I saw this error and got it fixed by installing the newest version of pymongo.
(at the time of writing)
pip install pymongo==3.5.1
I can't figure out why jupyter-lab is not working. something is broken and don't know where. I have searched the web for this and can't find a solution. COuld you please help. Appreciate it.

You need to install the dateutil library: https://pypi.python.org/pypi/python-dateutil/
(If you used a package manager, the dependencies for JupyterLab should already have been installed. If you didn't, then you will need to install the dependencies yourself.)
I'm having a 'Cannot import name StringIO' error message when importing dateutil which tries to import StringIO but cannot find it. Here is complete trace:

When I tried to use python3 to launch my program, i had this error:

Why I'm having this? i've installed numpy in my virtualenv with: pip install numpy
You are masking the built-in io module because you have a package named io in your project:
Traceback (most recent call last):
File "core/main.py", line 7, in <module>
from io.reader import *
File "/home/arbi/Work/sentimentpy/core/io/reader.py", line 4, in <module>
The line from io import StringIO finds /home/arbi/Work/sentimentpy/core/io, not the built-in module.
Rename that package or move it into a new top-level package name that doesn't conflict.
Your second error is unrelated; you simply don't have numpy installed for Python 3.
