Greetings,
I am totally new to Python, I don’t even know if this is the right place to ask this question. If this is the wrong place, I’d be grateful to pointers to the right place. I have python script to run that calls pandas. So I tried to instal the pandas package using: python3 -m pip install pandas. It tried but then dumped 100? error messages and then downloaded the next earliest one, got a fresh slew of errors, and this repeated without resolution. I am running MacOS 10.14.6 on a MacBookpro from late 2013. I installed python 3.10.0. I hope someone can help. Many thanks. Tobias Baskin
I tried to instal the pandas package using: python3 -m pip install pandas.
That looks correct to me.
Can you provide a transcript of the whole command and error output?
Paste it into a new message between lines containing only triple
backticks (```), i.e.:
```
your transcript here
```
For example, here (my Mac) on a python3 where pandas is already
installed:
[~]fleet2*> python3 -m pip install pandas
Requirement already satisfied: pandas in ./var/venv/3.9.2-homebrew/lib/python3.9/site-packages (1.2.5)
Requirement already satisfied: pytz>=2017.3 in ./var/venv/3.9.2-homebrew/lib/python3.9/site-packages (from pandas) (2019.3)
Requirement already satisfied: python-dateutil>=2.7.3 in ./var/venv/3.9.2-homebrew/lib/python3.9/site-packages (from pandas) (2.8.0)
Requirement already satisfied: numpy>=1.16.5 in ./var/venv/3.9.2-homebrew/lib/python3.9/site-packages (from pandas) (1.21.0)
Requirement already satisfied: six>=1.5 in ./var/venv/3.9.2-homebrew/lib/python3.9/site-packages (from python-dateutil>=2.7.3->pandas) (1.12.0)
If I make a new virtual environment (so that I have something without
pandas installed):
[~]fleet2*> python3 -m venv v1
[~]fleet2*> ./v1/bin/python3 -m pip install pandas

If you’re completely new to Python (and thus unfamiliar with the ecosystem), but plan to use Pandas and other data science packages, you might find it easier to get started with a Conda installation from Continuum:
Maybe you should report this on the pip issue tracker: Issues · pypa/pip · GitHub
Also, read some issues that match with your error message, to avoid posting a duplicated issue.
Cameron, thank you. OK, it is kind of long. I just want to mention that I installed a couple of other packages with no problem. But not pandas. Here is what I get after typing that install command:

Can you spot something?? Tobias
Thank you. As you can see below the “error message” is complex. I don’t understand it. I have searched in general for problems installing pandas and I could not understand the answers or was not sure that it applied to me. But checking with pip is a great idea. TB

Skip, Thanks. UM, I have seen references to Anaconda but I am confused about what it is. I expect to be running python scripts from the terminal window. Is Anaconda a separate program and interface? or does it load things that are then accessed via the terminal? And what is Jupyter?? Thank you! Tobias

They are Python implementations, separate than CPython. You could search some references here:
Anyway, you can keep going with a standard Python installation, and work on your installation issue 
Hi Tobias,
pip is trying to build certain scientific packages written in a mixture of Python, C and Fortran from source and appears to be failing because you don’t have a working C (and Fortran) development environment set up. I don’t know how you would go about setting that up on Mac OS, maybe somebody else can help.
Normally this is not something you should need, since most packages (including pandas and numpy) should come as pre-built binary packages. However, as Python 3.10 is brand new, many of these packages have not yet been updated.
The easiest solution is probably to switch to Python 3.9 for now and come back to Python 3.10 in a month or two.

Correction: Anaconda is a different distribution of Python, separate from the Python.org distribution. It still uses the CPython interpreter.
There are also implementations of the Python language other than CPython, such as PyPy and IronPython.

You are right @tjol, sorry 
Pandas does not yet have macOS wheels for Python 3.10 yet. The easiest way to get a working copy of Pandas is to install Python 3.9 instead, or as other suggested use conda.
