Python comes with a package installer called `pip` that is used to install Python packages from the Python Package Index (PyPI). If you have a Python version of 2.7.9 or later, or Python 3.4 or later, `pip` should already be installed. However, if you have an older version or it’s missing for some reason, you can use the following method to install `pip` using Python.
1. How To Install Pip In Cmd Use Python.
1.1 Download the `get-pip.py` script.
Open your web browser and go to the following link. To install pip for Python 2.7 : https://bootstrap.pypa.io/pip/2.7/get-pip.py. To install pip for Python3.7 or above : https://bootstrap.pypa.io/get-pip.py.
Right-click on the page and choose “Save Page As” to download the `get-pip.py` script to your computer. If you use Safari web browser on macOS, you should check the Page Source item from the Format drop down list in the Save As dialog window. Otherwise, Safari will save the file in webarchive format that make the file content not readable.
Then when you run the command python ./get-pip.py in below section, it will throw the error SyntaxError: Non-ASCII character ‘\xd1’ in file ./get-pip.py on line 1, but no encoding declared.
1.2 Open a terminal or command prompt.
Open a terminal on macOS or Linux, or a command prompt on Windows.
1.3 Navigate to the directory containing the `get-pip.py` script.
Use the `cd` command to change to the directory where you downloaded the `get-pip.py` script. For example, if you downloaded it to your “Downloads” folder on macOS or Linux, use the following command.
cd ~/Downloads
On Windows, if you downloaded it to your “Downloads” folder on drive C, use:
cd C:\Users\YourUsername\Downloads
1.4 Run the `get-pip.py` script.
Now that you’re in the correct directory, run the following command to execute the `get-pip.py` script use Python.
1.4.1 For Python2.
For Python 2, run the command python ./get-pip.py on macOS.
% python ./get-pip.py
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 Please upgrade your Python as Python 2.7 is no longer maintained.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.

Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
From the above output, we can see it has installed pip, pip2 and pip2.7 successfully in the folder /Users/administrator/Library/Python/2.7/bin, but it does not add them in the PATH environment variable. So you can run the command below to see the pip version.
% /Users/administrator/Library/Python/2.7/bin/pip --version pip 20.3.4 from /Users/administrator/Library/Python/2.7/lib/python/site-packages/pip (python 2.7) % /Users/administrator/Library/Python/2.7/bin/pip2 --version pip 20.3.4 from /Users/administrator/Library/Python/2.7/lib/python/site-packages/pip (python 2.7) % /Users/administrator/Library/Python/2.7/bin/pip2.7 --version pip 20.3.4 from /Users/administrator/Library/Python/2.7/lib/python/site-packages/pip (python 2.7)
Or you can add the path /Users/administrator/Library/Python/2.7/bin in the system environment variable PATH. Then you can run the command pip –version, pip2 –version, or pip2.7 –version directly in console.
1.4.2 For Python3.
For Python 3, run the command python3 get-pip.py on macOS.
python3 get-pip.py
If you have multiple Python versions installed on your system, make sure to use the appropriate command for the version you want to install `pip` for.
% /usr/local/bin/python3.10 ./get-pip.py

Successfully installed pip-23.2.1 wheel-0.41.0
From the above output, we can see it has installed pip, pip3 and pip3.10 successfully in the folder /Library/Frameworks/Python.framework/Versions/3.10/bin, but it does not add them in the PATH environment variable.
If you want to find where the newly pip3 is installed, you can run the command which pip3 to get it’s installed directory, and then go to the directory to see other pip versions. You can see that the pip3, pip3.10, and pip3.11 in the folder /usr/local/bin are all link files to the above pip3 executable files.
% which pip3 /usr/local/bin/pip3 % ls -l /usr/local/bin/pip* lrwxrwxr-x 1 root admin 67 Jul 28 04:29 /usr/local/bin/pip3 -> ../../../Library/Frameworks/Python.framework/Versions/3.10/bin/pip3 lrwxrwxr-x 1 root admin 70 Jul 28 04:29 /usr/local/bin/pip3.10 -> ../../../Library/Frameworks/Python.framework/Versions/3.10/bin/pip3.10 lrwxrwxr-x 1 root admin 70 Jul 21 00:39 /usr/local/bin/pip3.11 -> ../../../Library/Frameworks/Python.framework/Versions/3.11/bin/pip3.11
You can get the installed different pips version with the below command.
% /usr/local/bin/pip3.10 --version pip 23.2.1 from /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/pip (python 3.10) % /usr/local/bin/pip3.11 --version pip 23.1.2 from /Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/site-packages/pip (python 3.11)
2. Verify `pip` installation.
Once the installation process is complete, you can verify that `pip` is installed by running the following command.
For Python 2.
pip --version
For Python 3.
pip3 --version
You should see the version number of `pip` displayed, indicating that it’s successfully installed.
Now you have `pip` installed and ready to use. You can use `pip` to install various Python packages by simply typing `pip install packagename` or `pip3 install packagename` in the terminal or command prompt. Replace `packagename` with the name of the Python package you want to install.
3. How To Upgrade Pip Version.
3.1 How To Upgrade Pip To The Latest Version.
Here’s a step-by-step guide on how to upgrade pip to the latest version. Open a terminal on macOS or Linux, or a command prompt on Windows. Type one of the following commands based on your Python version and press Enter to upgrade pip.
For Python 2: pip install –upgrade pip or pip2 install –upgrade pip.
% /Users/administrator/Library/Python/2.7/bin/pip2 install --upgrade pip 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 Requirement already up-to-date: pip in /Users/administrator/Library/Python/2.7/lib/python/site-packages (20.3.4)
For Python 3: pip install –upgrade pip or pip3 install –upgrade pip.
% pip3 install --upgrade pip Requirement already satisfied: pip in /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages (23.2.1) % % pip3 --version pip 23.2.1 from /Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/pip (python 3.10)
If you have multiple Python versions installed on your system, make sure to use the appropriate command for the version of pip you want to upgrade.
For example, I installed both python 3.10 & python 3.11 on my macOS.

% /usr/local/bin/pip3.11 --version
