Broken Conda Installation After Conda Update Python

I have tried upgrading Python version on a Miniconda installation by running conda update python. The version was being taken from 3.8 to 3.10. This seems to have broken the installation. No matter what command I run, I get the following:
➜ project conda activate
Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Help on fixing this is appreciated.

module not found error in python while installing tar.gz file

I have a virtual env and I am trying to install a private (my company's) package into it. I download the tar.gz file in the project repo and then I do pip install pkg_name --find-links=".". But every time I get this error:
Traceback (most recent call last):
File "<string>", line 36, in <module>
File "<pip-setuptools-caller>", line 34, in <module>

ModuleNotFoundError: No module named 'distutils.command.bdist_conda'
I am using python=3.7.4 on macOs.
Any help is really appreciated.

Python: pip is installed but not working in windows

I have installed python 3.6.0, you don't need to install pip manually if you are using python (>3.3). But When I am trying to access pip (pip --version), it throws me two errors which mainly relate to not finding the module.
Description is given below.
C:\Users\sharma6>pip --version
Traceback (most recent call last):
File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 27, in <module>

During handling of the above exception, another exception occurred:

File "c:\python360\lib\site-packages\pip\_vendor\requests\packages\__init__.py", line 29, in <module>
import urllib3
ModuleNotFoundError: No module named 'urllib3'
Even when I import socket (>>>import socket)in python interpreter , It shows me "Can not found the module" error .
>>> import socket
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\python352\lib\socket.py", line 49, in <module>
import _socket
zipimport.ZipImportError: can't find module '_socket
Could someone tell me about the errors and how to resolve them because I need pip to work properly.

Add your all path in your system variable instead of adding in user variable.
It worked for me!!! :)

You should try to write
python -m pip --version
If this gives an error message, install pip by downloading get-pip.py from https://pip.pypa.io/en/stable/installing/ and install with
python get-pip.py
Installing with pip is then done by
python -m pip install [package name]

rpy2 doesn't work - requires libiconv.so.2

I have a relatively fresh installation of anaconda, in which I installed rpy2 using "conda install rpy2". However, when I try running it, I get this error, e.g.:
> /[dir]/anaconda/bin/python -m 'rpy2.tests'
Traceback (most recent call last):
File "/[dir]/anaconda/lib/python2.7/runpy.py", line 174, in _run_module_as_main

from rpy2.rinterface._rinterface import (baseenv,
ImportError: libiconv.so.2: cannot open shared object file: No such file or directory
What is this libiconv.so.2, and why doesn't it work straight from the box?

I think you need to conda install -c r libiconv or perhaps install r-essentials, which contains libiconv.

PyInstaller error with lxml module

In my script I have imported lxml module. I made an executable file from my script using pyinstaller on Ubuntu. When I run the executable file in terminal I get the following error:
Traceback (most recent call last):
File "<string>", line 15, in <module>
File "/home/yaa110/workspace/Python27/src/PyInstaller-2.1/PyInstaller/loader/pyi_importers.py", line 270, in load_module
exec(bytecode, module.__dict__)
File "/home/yaa110/workspace/Python27/src/PyInstaller-2.1/process/build/process/out00-PYZ.pyz/lxml.html", line 42, in <module>
ImportError: cannot import name etree
How can I fix it?
I'm using Python 2.7.5 on Ubuntu
