If you are wondering why this error occurs and how to fix it. Then, you must continue reading.

This article discusses important details that will help you troubleshoot the pip install invalid syntax, a SyntaxError in Python.

So without further ado, let’s get started!

What is pip?

Pip is a package manager for Python packages. It is a helpful tool that allows users to install and manage libraries and dependencies. That is not distributed as part of the standard library.

To use pip, you need to run it from the command line rather than the Python interpreter. Pip is a program designed to install modules so that you can utilize them in Python.

Once you have installed the desired module, you can then open the Python shell and import it using the import statement.

It’s important to note that the Python shell functions as an interactive interpreter where you input Python code, not commands.

✅ python3 -m pip install requests
✅ py -m pip install requests

Note: this is just an example module if you have a different module to be installed. Ensure to change it to your preference.

Solution 3: Install the package or module in Python script

import subprocess
import sys


def install(package):
    subprocess.check_call([sys.executable, "-m", "pip", "install", package])


install('selenium')

Output:

pip install syntaxerror

Note: Ensure to change the selenium with the name of the module you’re trying to install.
