Installation and Use of Python package manager pip

This article describes how to install and use pip in the Python package manager.

During this time, I was busy with providing services to my friends. after a long time, I had to write a blog for a long time. There are two tasks: one is the automatic mail sending script and the other is the data processing software. The non-Python system library is used when data processing software is used. it is a third-party library, pandas and numpy. In fact, pandas contains numpy, later I found that after installing numpy in the source code, I couldn't install pandas. I checked it and unmounted numpy. I used a Python package manager to manage the third-party packages, download this series of third-party packages. Unfortunately, there is time now. I will introduce this package manager to you here.

Pip is currently the most popular Python package management tool. it is used as a substitute for easy_install, but there are still a lot of functions built on setuptools.

Install

Official website installation: https://pip.pypa.io/en/latest/installing/

The official website is very detailed. here I will use the old version to install it ~

I will introduce the installation of Python pip in CentOS. to ensure the versatility of the platform, I will use the source code to install pip.

Cd to the directory where you want to download pip.

# cd  /usr/local/src

#wget "https://pypi.python.org/packages/source/p/pip/pip-1.5.4.tar.gz

# tar -xzvf pip-1.5.4.tar.gz# cd pip-1.5.4# python setup.py install

How do I install it? I am also an easy-to-use person ~

Run the following command in CentOS to install CentOS:

#python -m pip install --upgrade pip

Or

#yum install python-pip

Yes, depending on your preferences ~

Use

Pip installs a third-party package

# pip install SomePackage

List installed packages

# pip list

View installed package details

# pip show --files SomePackage

Pip upgrade package

# pip install --upgrade SomePackage

Pip uninstall package

pip uninstall SomePackage

Okay. now, the Python package manager pip is finished. it is indeed very short, but it is very useful ~
