Detailed explanation of the update command for the software (library) under linux

Sudo apt-get install package name or sudo pip install package name is often used when installing packages under a ubuntu server, so what's the difference between the two?

1. Difference

Pip is used to install all dependent packages from PyPI (https://www.python.org/) python, and you can choose to install any previous version of dependent packages that have been uploaded on PyPI, personally considered to be python-related packages and third-party packages as well as various versions

Apt-get can be used to install software, update sources, or update typical dependency packages from Ubuntu (https://launchpad.net/ubuntu). A typical installation means that it is only installing (the latest release, or the most recent) a single version, and we cannot decide which version of the dependency package we want to install or choose the previous version.

Personally, it is easy to distinguish: after all, one is to update a system-level package, and the other is to update a programming language-level package (library).

two。 Installation and application

Apt-get can be used directly in the format

$sudo apt-get install/delete package$ sudo apt-get-f install # repair installation $sudo apt-get dist-upgrade # upgrade system $sudo apt-get upgrade # update installed package $apt-get source package # download the source code of the package $sudo apt-get build-dep package # install the relevant compilation environment $sudo apt-get clean & & sudo apt-get autoclean # clean up useless packages

Pip needs to be installed to use. The installation process is as follows (for Ubuntu 10.10 and above), using the format: pip install package.

$sudo apt-get install python-pip python-dev build-essential$ sudo pip install-upgrade pip
