Install packages from:
- PyPI (and other indexes) using requirement specifiers.
- VCS project urls.
- Local project directories.
- Local or remote source archives.
pip also supports installing from "requirements files", which provide
an easy way to specify a whole environment to be installed.

The handling of dependencies depends on the upgrade-strategy used.s --upgrade-strategyt upgrade_strategyt eagert choicess only-if-neededs3 Determines how dependency upgrading should be handled. "eager" - dependencies are upgraded regardless of whether the currently installed version satisfies the requirements of the upgraded package(s). "only-if-needed" - are upgraded only when they do not satisfy the requirements of the upgraded package(s).s --force-reinstallt force_reinstallsK When upgrading, reinstall all packages even if they are already up-to-date.s -Is --ignore-installedt ignore_installeds5 Ignore the installed packages (reinstalling instead).s --usert

(See the Python documentation for site.USER_BASE for full details.)s --eggt as_eggs� Install packages as eggs, not 'flat', like pip normally does. This option is not about installing *from* eggs. (WARNING: Because this option overrides pip's normal install logic, requirements files may not behave as expected.)s --roott root_paths= Install everything relative to this alternate root directory.s --strip-file-prefixt strip_file_prefixt prefixs5 Strip given prefix from script paths in wheel RECORD.s --prefixt prefix_pathsI Installation prefix where lib, bin and other top-level folders are placeds --compilet compiles Compile py files to pycs --no-compilet store_falses Do not compile py files to pyci ( t superR t __init__t cmd_optst
