How do I fix pip on mac?

By usin pip install simpleaudio I get the following:
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 will drop support for Python 2.7 in January 2021. More details about Python 2 support in pip can be found at https://pip.pypa.io/en/latest/development/release-process/#python-2-support pip 21.0 will remove support for this functionality.
Defaulting to user installation because normal site-packages is not writeable

Though, I am a Python programmer with little experience. It sounds like your are still using Python 2.7 which has been deprecated(not longer supported). To solve this, I recommend you go to python.org and then hover over the downloads button and then download the current version of Python.

Unable to install pytransform using pip, shows this after entering the command

I dont know why it keeps saying the same error again and again

The package you are trying to install (which is ~ 5 years old) has
MDAnalysis==0.8.1
as a requirement, which is a version from 2014 and was therefore written for python 2x. In your error message you can see that in the setup.py of MDAnalysis, we have the line
print "MDAnalysis requires Python 2.6 or better. Python %d.%d detected" %
which is the python 2x syntax of print(no parantheses).
You have multiple options now:
Try to find a differerent library than pytransform that serves your need and is more up to date
Download the pytransform tar.gz file manually, extract it and replace MDAnalysis==0.8.1 in the requires.txt with MDAnalysis. This is not guaranteed to work though, as the API might have changed
Download the MDAnalysis 0.8.1 source code and try to adjust it to python 3 syntax. This might be a lot of work though
Use python2 for your project. Do note though that python2 has reached it's end of life and is no longer supported, e.g. by the newest version of pip
Note:
Looking at the code of pytransform, option 2 might be the easiest. Even if it doesn't work with the newest MDAnalysis out of the box, the code is only 74 lines long, so changing it to a newer MDAnalysis API should not be too much work

cloudant module will not install with pip

trying to install the cloudant module on a raspberry pi ver 1 rev b using the instructions from IBM's web page.
first: git clone https://github.com/IBM-Cloud/get-started-python
then: cd get-started-python
finally: pip install -r requirements.txt
I want to use the cloudant module with python 2.7 I've read about the environment variable possibly being an issue, but honestly i'm lost. I've read many posts about problems installing, but so far nothing works...
I get the following error message:

UPDATE:
so this is my code:
from cloudant.client import cloudant
running my code using python3 code.py I get the error message"
Traceback (most recent call last):
File "code.py", line 1, in <module>
from cloudant.client import cloudant
ModuleNotFoundError: No module named 'cloudant'
While I don't fully understand why changing my import statement to from cloudant import Cloundant fixes the issue...

Parameter encoding was added to open() in Python 3.0. This code in setup.py is Python3-only despite the packages declares compatibility with Python2. Please note they provide wheels only for Python3.
Either using encoding is a bug or declaring compatibility with Python2 is a bug. Which one is for the authors to decide. Report the problem and let's them to resolve.
Or try Python3.

How do I install scientificpython package successfully on Ubuntu 18.04?

I have installed Python 3.7.6 on my Ubuntu 18.04 system. I am trying to install package called "scientificpython" but consistently getting the following error message.

How do I resolve this problem?

Based on your traceback and the ScientificPython home page:
Therefore ScientificPython can be used only with Python 2.7 and NumPy 1.8, but not with later releases of either software.
You are using Python 3.7.6, which does not recognize print as a statement as it existed in Python 2, for starters.
You can install Python 2 from source, or use a tool such as pyenv to manage multiple Python versions alongside each other.

Try to install ScientificPython by specifying the version
Command:
pip install ScientificPython==2.9.4
Or Try:
python -m pip install ScientificPython==2.9.4
If problem still persist, then try to download the tar file of the package then install it manually. Available links are provided.

Or
https://src.fedoraproject.org/lookaside/extras/ScientificPython/ScientificPython-2.8.1.tar.gz/
Or
https://osdn.net/frs/g_redir.php?m=kent&f=anuga%2Fanuga_support_software%2Fubuntu_8.10%2FScientificPython-2.9.0.tar.gz
But ScientificPython works only with Python version 2. So it is recommended to use the alternative package called Scipy.
Command:
pip install scipy
Or
python -m pip install --user numpy scipy matplotlib ipython jupyter pandas sympy nose
I hope it would resolve the error.

When trying to install strom i am receiving the above error.

The package storm for Python has not been maintained. The latest version 0.20 is released at 2013. The project doesn't support Python 3 at all.

It's in package, syntax error. You need to change comma(this symbol ' , ') in said line:
File
"/private/var/folders/lk/wrg280_17c78l9kysqx26pdc0000gp/T/pip-install-so_kwd18/storm/ez_setup.py",
line 106
except pkg_resources.VersionConflict, e:
to 'as', it should look like:
except pkg_resources.VersionConflict as e: # in package there is ','
But if you are just starting project, DO NOT use storm, as it's last update was nearly 7 years ago and it's not clear if it's compatible with python 3.
I don't know what you are using it for but search for something with constant support. If you are not sure which package is getting support search for last realease date on:
PyPi library

Installing directly from shell / terminal may help rather then to do it in program.
