Issue with pip - Traceback error - Messed up installation? [duplicate]

This question already has answers here:
The 'pip==7.1.0' distribution was not found and is required by the application
(11 answers)
Closed 1 year ago.
I am having some issues running pip on my iTerm on my Mac (Big Sur 11.4)
I have already tried a couple things.
a. removed the Python framework from /Library/Frameworks (in an effort to clean remove python 3)
b. removed the Python apps from Applications
(that said, python3 still runs the interpreter)
Here is the error message, below.
Any input would be appreciated
Thank you

My guess is that you have more than one soft links of pip in your default directory. Maybe try checking it by where pip3 and rm the soft links of older versions.

After upgrading pip, it no longer works

I recently updated my Homebrew installation of Python 3.8.2 to 3.8.3. After doing so, I ran
$ pip3 install -U pip
in order to check for any pip updates. It updated my installation of pip from 20.0.2 to 20.1.1, and ever since I ran that command, pip throws an error any time I try to use it. Here's the error:

It seems that something went wrong during the upgrade process that failed to change the version check within the code. I saw this similar question, but the accepted answer is not working for me. How can I make pip usable again?

As per Python documentation, the correct way to use pip now would be via the correct Python executable, e.g.
python3 -m pip install -U pip

I had experienced a similar problem on my Ubuntu and here's how I solved my problem:
First restore the older version by reinstalling it from your OS package manager (You may need to uninstall first).
Upgrade to the latest version for your user (as opposed to installing in a system location) with the following command
pip3 install --user -U pip
Hope this helps.

`eb init` fails with pkg_resources.ContextualVersionConflict PyYAML 4.1

I am having some trouble deploying my elastic beanstalk app from a bitbucket pipeline. This same code had been working without issue, so my best guess is some kind of dependency issue.
(awsebcli version 3.14.1)
The image for the pipeline is python:3.5.2
and here's the failing step:
- step:
name: Test Deploy
deployment: test
caches:
- pip
script:
- pip install awsebcli --upgrade
- eb init myAppName -r us-east-1 -p Python # This line started failing :'(
- eb deploy myAppName-dev-1
and the error output:
eb init myAppName -r us-east-1 -p Python

So if I'm reading this right, I have PyYAML 4.1 when I need something less than 4.

I changed the pip install line to explicitly use an older version of PyYAML and that seems to have worked...
Changed
pip install awsebcli --upgrade
To
pip install pyYAML==3.12 awsebcli --upgrade

To give a bit of a background. I installed python3 with brew and I uninstalled it thereafter.
Now I cannot install ruamel.yaml
Has anybody had the same issue?
How did you solve it?

You should do a pip list and check your version of setuptools should be (28.8.0). If you have an older version, upgrade with pip install -U setuptools.
You should consider upgrading from 2.7.10 to a newer version of Python 2 (currently 2.7.14), which should solve your SSL problems. Make sure you don't overwrite the system python if you are running on Linux.

I was able to resolve this by downgrading the python version from 3.10.+ to 3.9.+

Python pkg_resources.DistributionNotFound Error

I am trying to install Trac on windows (64-bit) and i have followed all the installation guidelines.
But when i try to run the trac standalone server using tracd, i get this error:

pkg_resources.DistributionNotFound: The 'trac==1.0' distribution was not found and is required by the application
I have installed trac and it is present in the site package directory where i installed python.
-a--- 4/15/2016 4:25 PM 1894048 trac-1.0-py2.7.egg
So why is it not able to find trac?
i do not have admin access on this PC. I do not know python, i just want to install and learn how to use Trac.
