Never installed them so cannot provide specifics but those messages appear to be python messages.

pip3 is an OS command not a python command.

I tried from the python command box … did not work. Got the following errors

 

SyntaxError: invalid syntax
>>> `pip --version`
 File "<stdin>", line 1
   `pip --version`
   ^
SyntaxError: invalid syntax
>>> pip --version
Traceback (most recent call last):
 File "<stdin>", line 1, in <module>
NameError: name 'pip' is not defined. Did you mean: 'zip'?
>>>

Just trying to type the command returns this error

 

>>> pip install pandas matplotlib openpyxl
 File "<stdin>", line 1
   pip install pandas matplotlib openpyxl
       ^^^^^^^
SyntaxError: invalid syntax
>>>

Seems like the pip module is not being detected. What OS are you using and how did you install python ? 

i installed python from the python.org site… downloaded the windows installer

 

I'm using Windows 11

check that python is in your PATH 

You should have something like this in your PATH depending on the python version you have, the last directory might change. In side the script folder you should have pip typically that gets installed when you install python.  

 

C:\Users\youruser\AppData\Local\Programs\Python\Python310
C:\Users\youruser\AppData\Local\Programs\Python\Python310\Scripts

Select allOpen in new window

>>I tried from the python command box

Again, pip isn't a python command.

Since you say Windows:  Go to a CMD prompt and try pip and/or pip3 depending on the version you need.

You can also try installing the latest pip by downloading the get-pip python script from here:  https://bootstrap.pypa.io/get-pip.py  and running the script from the command line

 python get-pip.py

Select allOpen in new window

to install the latest version of pip.

The Command Line? in Windows 11? This is a work machine… I can't find the command line prompt

 

Meant the command prompt 

 

>>This is a work machine…

You may need admin privs.

Hit the Windows key, type CMD

Just in case, the Windows key on most keyboards is here:

You could try running the command  from the Run dialog box, which you can open using Windows Key + R.

>>You could try running the command  from the Run dialog box

Problem with that is that if there is an error, the cmd.exe window will close before you can see the error.

IMHO, it is always best to run OS commands from the command prompt be it Windows or Linux.

It is becoming more common to disable pip  to install systemwide modules.
You may want to look into venv to use pip.

Also many distro's provide various python modules to install systemwide as a package...
try:
emerge dev-python/pandas  (gentoo)
dnf install python3-pandas   (rhel / centos / ... ) if EPEL is active.
apt install python3-pandas   (debian, ubuntu)
pacman -Syi python-pandas   (arch, needs Extra repo).

@noci,
While informative, Rex stated they are using Windows 11.

Agree... i answer with what i use... As i never use windows...
Then again there is the Fine Manual
From: https://pandas.pydata.org/pandas-docs/stable/getting_started/install.html

Reading it shows:

Installing with Anaconda
For users that are new to Python, the easiest way to install Python, pandas, and the packages that make up the PyData stack (SciPy, NumPy, Matplotlib, and more) is with Anaconda, a cross-platform (Linux, macOS, Windows) Python distribution for data analytics and scientific computing. Installation instructions for Anaconda can be found here.

I needed admin rights… IT strikes at productivity once again (eye rolls)

 

Thank you all

If you need it, get Management make them install it.

If you want to run a pilot program to prove to Management how it can benefit the company, get them to install it or give you a computer not connected to the network as a sandbox.

If you just want to mess around personally, you shouldn't be doing that on a work computer.  That is how bad things happen and why you aren't allowed to install anything.

All that said and you assume ALL the risk of 'Shadow IT' ( https://en.wikipedia.org/wiki/Shadow_IT ), up to being fired and possibly prosecuted:
There are a few links out there on installing Pandas on Windows without Admin rights.

I assume the other products have similar installations.

I'll let you find them so we can claim:  You didn't get the steps from EE!
