The SyntaxError: invalid syntax when running pip install occurs because the command is being executed inside the Python interpreter instead of the system command prompt (terminal, CMD, or PowerShell).
pip is a command-line tool, not a Python keyword, so it cannot be run directly within the interactive Python shell (indicated by the >>> prompt). To resolve this error, you must exit the Python interpreter by typing exit() or pressing Ctrl+D/Ctrl+Z, and then run the installation command from your operating system's terminal.
Correct Command: Run
pip install package_namedirectly in the terminal, not in the Python shell.Alternative Method: If you must run it from within a Python script, use
python -m pip install package_nameorimport pip; pip.main(['install', 'package_name']).Common Pitfall: Ensure you are not using the
>>>prompt; if you see>>>, you are in the wrong environment.
pip is run from the command line, not the Python interpreter. It is a program that installs modules, so you can use them from Python. Once you have installed the module, then you can open the Python shell and do import selenium.
The Python shell is not a command line, it is an interactive interpreter. You type Python code into it, not commands.

Use the command line, not the Python shell (DOS, PowerShell in Windows).
C:\Program Files\Python2.7\Scripts> pip install XYZ
If you installed Python into your PATH using the latest installers, you don't need to be in that folder to run pip
Terminal in Mac or Linux
$ pip install XYZ

I am new to Python, getting Syntax Error: invalid syntax pip install Flask Flask-SQLAlchemy
Syntax error with pip install...
Pip is a binary not a python function... You run it directly from cmd.exe

EDIT : Problem solved! Thanks again to those who helped me ;-)
Hello, I just started to use Python because I need it to install a module in cmd.exe (LaZagne project : https://github.com/AlessandroZ/LaZagne ). However, I've come across an error that I haven't been able to fix despite my research, which is why I'm relying on you...
When I type the command "pip install pyasn1 psutil" in cmd.exe, the terminal reply that there's a syntax error & point the i of install, I looked a little bit everywhere on the web but in spite of that, there's not really a solution that seems to work in my case :(
Considering screenshots are not allowed, here's a retranscription of my terminal :
Microsoft Windows [version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. Tous droits réservés.
C:\Windows\system32>python
Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:20:19) [MSC v.1925 32 bit (In
tel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> pip install pyasn1 psutil
File "<stdin>", line 1
pip install pyasn1 psutil
^
SyntaxError: invalid syntax
>>>
Also to be more precise, here's what I'm trying to install, if I understood correctly, I have to copy what is marked on the page in cmd.exe...even if I'm not entirely sure that it's exactly that tbh : https://github.com/AlessandroZ/LaZagne/wiki/Requirements
Concerning Python version, it's the most recent one as you can see, so I don't think the problem comes from there...
Well...I think I've said everything, I hope you'll be able to help me ;-)
Thanks in advance ^^

Use on the powershell/command command line.
py -m pip install something
Using py makes sure the latest version of Python installed is used.
BUT
You should avoid installing libraries into your base Python installation. Instead, create and activate project specific virtual environments using the Python venv command. (Check documentation.)
Those are not the same commands I found on their website: This is what I found: If Python 3 is installed:
python3 -m pip install --upgrade pip
python3 -m pip install jupyter
For Python 2:
python -m pip install --upgrade pip
python -m pip install jupyter
Hope this helps.
So, I found a solution. I needed to add pip to my PATH Environment variable. I had python added, but I also needed to add the directory where pip was located.
Hi, I've been having trouble with running the line
python -m pip install --user -r requirements.txt
I've also tried
pip install --user -r requirements.txt pip3 install -r requirements.txt pip3 install selenium
But I get "Invalid syntax". I'm using Python 3.11.9 and using IDLE
