Learn how to install pip to your Python2!

Teach you step by step how to install pip in Python2!

With the continuous development of Python, Python's package management tool pip has also become an indispensable part. pip can easily install, upgrade and manage various third-party libraries and modules of Python, greatly improving development efficiency. This article will introduce in detail how to install pip in a Python2 environment and provide specific code examples.

Step 1: Check the Python version

First, we need to make sure that the installed Python version is Python2. Open a terminal or command line window and enter the following command:

$ python -V

If the displayed result is Python 2.x.x, it means Python2 has been installed. If Python2 is not installed, please download and install it first.

Step 2: Download the get-pip.py script

Execute the following command in the terminal or command line window to download the get-pip.py script:

$ curl https ://bootstrap.pypa.io/pip/2.7/get-pip.py -o get-pip.py

Or use the wget command to download:

$ wget https://bootstrap .pypa.io/pip/2.7/get-pip.py

Step 3: Install pip

Execute the following command in the terminal or command line window to start installing pip:

$ python get-pip.py

If your Python2 environment is configured with multiple versions of Python, you need to specify a specific Python interpreter to execute the above command. For example, if the path to install Python2 is "/usr/local/bin/python", execute the command:

$ /usr/local/bin/python get-pip.py

Installation The process may take some time, just wait patiently.

Step 4: Verify whether pip is installed successfully

After the installation is completed, we can execute the following command to verify whether pip has been installed successfully:

$ pip -V

If the displayed result is pip 21.3.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7), it means that pip has been successfully installed.

Step 5: Use pip to install third-party libraries

Now, we can use pip to install the third-party libraries we need. Taking the installation of the requests library as an example, execute the following command:

$ pip install requests

pip will automatically download and install the requests library and its dependencies.

Step 6: Upgrade pip

If you find that your pip version is too old, you can upgrade it with the following command:

$ pip install --upgrade pip

pip will automatically update to the latest version.

At this point, you have successfully installed pip and can use it to install, upgrade and manage Python's third-party libraries and modules.
