1. Use easy_install

Easy_install this is probably the oldest way to install packages, and almost no one uses it now. Here are some examples of easy_install installation

# find the latest version from PyPI by package name Automatically download, compile, install $easy_install pkg_name # find a link from the specified download page through the package name to install or upgrade the package $easy_install-f http://pythonpaste.org/package_index.html # specify the package address online install $easy_install http://example.com/path/to/MyPackage-1.2.3.tgz # install $easy_install xxx.egg from the local .egg file

two。 Use pip install

Pip is the most mainstream package management solution, and using pip install xxx, you can search for and install xxx from PYPI (if the package exists).

Here are only some common installation examples of pip install

$pip install requests # premise you must make sure that you have downloaded the pkg package to the / local/wheels directory $pip install-- no-index-- find-links=/local/wheels pkg # installed package version 2.1.2$ pip install pkg==2.1.2 # installed package must be greater than or equal to 2.1.2$ pip install pkg > = 2.1.2 # installed package must be less than or equal to 2.1.2$ pip install pkg
