You can use the following command to determine whether it has been installed:

pip --version

If you have not installed it yet , you can use the following method to install:

 $ curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py   # 下载安装脚本
 $ sudo python get-pip.py    # 运行安装脚本

Note: Which version of Python is used to run the installation script, pip will be associated with that version. If it is Python3, execute the following command:

$ sudo python3 get-pip.py # Run the installation script.

Generally, pip corresponds to Python 2.7, and pip3 corresponds to Python 3.x.
