NAME

6       pip-install - description of pip install command
7

DESCRIPTION

9       Install packages from:
10
11       · PyPI (and other indexes) using requirement specifiers.
12
13       · VCS project urls.
14
15       · Local project directories.
16
17       · Local or remote source archives.
18
19       pip  also  supports installing from "requirements files", which provide
20       an easy way to specify a whole environment to be installed.

USAGE

24          pip install [options] <requirement specifier> [package-index-options] ...
25          pip install [options] -r <requirements file> [package-index-options] ...
26          pip install [options] [-e] <vcs project url> ...
27          pip install [options] [-e] <local project path> ...
28          pip install [options] <archive url/path> ...
29

OPTIONS

31       -r, --requirement <file>
32              Install from the given requirements file.  This  option  can  be
33              used multiple times.
34
35       -c, --constraint <file>
36              Constrain versions using the given constraints file. This option
37              can be used multiple times.
38
39       --no-deps
40              Don't install package dependencies.
41
42       --pre  Include pre-release and development versions.  By  default,  pip
43              only finds stable versions.
44
45       -e, --editable <path/url>
46              Install  a  project  in  editable mode (i.e. setuptools "develop
47              mode") from a local project path or a VCS url.
48
49       -t, --target <dir>
50              Install packages into <dir>. By default this  will  not  replace
51              existing files/folders in <dir>. Use --upgrade to replace exist‐
52              ing packages in <dir> with new versions.
53
54       --platform <platform>
55              Only use wheels compatible  with  <platform>.  Defaults  to  the
56              platform of the running system.
57
58       --python-version <python_version>
59              The   Python   interpreter   version   to   use  for  wheel  and
60              "Requires-Python" compatibility checks. Defaults  to  a  version
61              derived  from the running interpreter. The version can be speci‐
62              fied using up to three  dot-separated  integers  (e.g.  "3"  for
63              3.0.0,  "3.7"  for 3.7.0, or "3.7.3"). A major-minor version can
64              also be given as a string without dots (e.g. "37" for 3.7.0).
65
66       --implementation <implementation>
67              Only use wheels compatible with Python implementation <implemen‐
68              tation>, e.g. 'pp', 'jy', 'cp',  or 'ip'. If not specified, then
69              the current interpreter implementation is  used.   Use  'py'  to
70              force implementation-agnostic wheels.
71
72       --abi <abi>
73              Only   use   wheels  compatible  with  Python  abi  <abi>,  e.g.
74              'pypy_41'.  If not specified, then the current  interpreter  abi
75              tag  is  used.  Generally you will need to specify --implementa‐
76              tion, --platform, and --python-version when using this option.
77
78       --user Install to the Python user install directory for your  platform.
79              Typically  ~/.local/,  or  %APPDATA%Python  on Windows. (See the
80              Python documentation for site.USER_BASE for full details.)
81
82       --root <dir>
83              Install everything relative to this alternate root directory.
84
85       --prefix <dir>
86              Installation prefix where lib, bin and other  top-level  folders
87              are placed
88
89       -b, --build <dir>
90              (DEPRECATED)  Directory  to  unpack  packages into and build in.
91              Note that an initial build still  takes  place  in  a  temporary
92              directory.  The  location  of  temporary directories can be con‐
93              trolled by setting the TMPDIR environment variable (TEMP on Win‐
94              dows)  appropriately.  When  passed,  build  directories are not
95              cleaned in case of failures.
96
97       --src <dir>
98              Directory to check out editable projects into. The default in  a
99              virtualenv is "<venv path>/src". The default for global installs
100              is "<current dir>/src".
101
102       -U, --upgrade
103              Upgrade all specified packages to the newest available  version.
104              The  handling  of  dependencies  depends on the upgrade-strategy
105              used.
106
107       --upgrade-strategy <upgrade_strategy>
108              Determines how dependency upgrading should be handled  [default:
109              only-if-needed].  "eager" - dependencies are upgraded regardless
110              of  whether  the  currently  installed  version  satisfies   the
111              requirements of the upgraded package(s). "only-if-needed" -  are
112              upgraded only when they do not satisfy the requirements  of  the
113              upgraded package(s).
114
115       --force-reinstall
116              Reinstall all packages even if they are already up-to-date.
117
118       -I, --ignore-installed
119              Ignore  the installed packages, overwriting them. This can break
120              your system if the existing package is of a different version or
121              was installed with a different package manager!
122
123       --ignore-requires-python
124              Ignore the Requires-Python information.
125
126       --no-build-isolation
127              Disable  isolation  when  building a modern source distribution.
128              Build  dependencies  specified  by  PEP  518  must  be   already
129              installed if this option is used.
130
131       --use-pep517
132              Use   PEP   517   for   building   source   distributions   (use
133              --no-use-pep517 to force legacy behaviour).
134
135       --install-option <options>
136              Extra arguments to be supplied to the setup.py  install  command
137              (use      like     --install-option="--install-scripts=<sys.pre‐
138              fix>/local/bin"). Use multiple --install-option options to  pass
139              multiple options to setup.py install. If you are using an option
140              with a directory path, be sure to use absolute path.
141
142       --global-option <options>
143              Extra global options to be supplied to the setup.py call  before
144              the install command.
145
146       --compile
147              Compile Python source files to bytecode
148
149       --no-compile
150              Do not compile Python source files to bytecode
151
152       --no-warn-script-location
153              Do not warn when installing scripts outside PATH
154
155       --no-warn-conflicts
156              Do not warn about broken dependencies
157
158       --no-binary <format_control>
159              Do  not use binary packages. Can be supplied multiple times, and
160              each time adds to the existing value. Accepts either ":all:"  to
161              disable  all  binary packages, ":none:" to empty the set (notice
162              the colons), or one or more package names  with  commas  between
163              them  (no colons). Note that some packages are tricky to compile
164              and may fail to install when this option is used on them.
165
166       --only-binary <format_control>
167              Do not use source packages. Can be supplied multiple times,  and
168              each  time adds to the existing value. Accepts either ":all:" to
169              disable all source packages, ":none:" to empty the set,  or  one
170              or more package names with commas between them. Packages without
171              binary distributions will fail to install when  this  option  is
172              used on them.
173
174       --prefer-binary
175              Prefer older binary packages over newer source packages.
176
177       --require-hashes
178              Require a hash to check each requirement against, for repeatable
179              installs. This option is implied when any package in a  require‐
180              ments file has a --hash option.
181
182       --progress-bar <progress_bar>
183              Specify     type     of     progress     to     be     displayed
184              [off|on|ascii|pretty|emoji] (default: on)
185
186       --no-clean
187              Don't clean up build directories.
