Installing Python packages from local file system folder to virtualenv with pip

Question

Is it possible to install packages using pip from the local filesystem   I have run python setup py sdist for my package  which has created the appropriate tar gz file  This file is stored on my system at  srv pkg mypackage mypackage-0 1 0 tar gz   Now in a virtual environment I would like to install packages either coming from pypi or from the specific local location  srv pkg   Is this possible   PS I know that I can specify pip install  srv pkg mypackage mypackage-0 1 0 tar gz  That will work  but I am talking about using the  srv pkg location as another place for pip to search if I typed pip install mypackage

What about    pip install --help       -e  --editable  lt path url gt    Install a project in editable mode  i e  setuptools                                develop mode   from a local project path or a VCS url    eg  pip install -e  srv pkg  where  srv pkg is the top-level directory where  setup py  can be found

Assuming you have virtualenv and a requirements txt file  then you can define inside this file where to get the packages     Published pypi packages  PyJWT  1 6 4 email validator  1 0 3   Remote GIT repo package  this will install as django-bootstrap-themes git https   github com marquicus django-bootstrap-themes egg django-bootstrap-themes   Local GIT repo package  this will install as django-knowledge git file    soft SANDBOX python django forks django-knowledge egg django-knowledge

I am pretty sure that what you are looking for is called --find-links option  You can do pip install mypackage --no-index --find-links file    srv pkg mypackage

This is the solution that I ended up using   import pip   def install package         Debugging       pip main   install    --pre    --upgrade    --no-index                  --find-links     package   --log-file    log txt    -vv        pip main   install    --upgrade    --no-index    --find-links     package     if   name         main         install  mypackagename       raw input  Press Enter to Exit    n     I pieced this together from pip install examples as well as from Rikard s answer on another question  The  --pre  argument lets you install non-production versions  The  --no-index  argument avoids searching the PyPI indexes  The  --find-links    argument searches in the local folder  this can be relative or absolute   I used the  --log-file    log txt   and  -vv  arguments for debugging  The  --upgrade  argument lets you install newer versions over older ones   I also found a good way to uninstall them  This is useful when you have several different Python environments  It s the same basic format  just using  uninstall  instead of  install   with a safety measure to prevent unintended uninstalls   import pip   def uninstall package       response   raw input  Uninstall   s    y n   n    package      if  y  in response lower              Debugging           pip main   uninstall   package   -vv            pip main   uninstall   package       pass   if   name         main         uninstall  mypackagename       raw input  Press Enter to Exit    n     The local folder contains these files  install py  uninstall py  mypackagename-1 0 zip

To install only from local you need 2 options    --find-links  where to look for dependencies  There is no need for the file    prefix mentioned by others  --no-index  do not look in pypi indexes for missing dependencies  dependencies not installed and not in the --find-links path      So you could run from any folder the following    pip install --no-index --find-links  srv pkg  path to mypackage-0 1 0 tar gz   If your mypackage is setup properly  it will list all its dependencies  and if you used pip download to download the cascade of dependencies  ie dependencies of depencies etc   everything will work    If you want to use the pypi index if it is accessible  but fallback to local wheels if not  you can remove --no-index and add --retries 0  You will see pip pause for a bit while it is try to check pypi for a missing dependency  one not installed  and when it finds it cannot reach it  will fall back to local  There does not seem to be a way to tell pip to  look for local ones first  then the index

I am installing pyfuzzybut is is not in PyPI  it returns the message  No matching distribution found for pyfuzzy   I tried the accepted answer   pip install  --no-index --find-links file    Users victor Downloads pyfuzzy-0 1 0 pyfuzzy   But it does not work either and returns the following error      Ignoring indexes  https   pypi python org simple   Collecting pyfuzzy     Could not find a version that satisfies the requirement pyfuzzy  from versions      No matching distribution found for pyfuzzy   At last   I have found a simple good way there   https   pip pypa io en latest reference pip install html  Install a particular source archive file    pip install   downloads SomePackage-1 0 4 tar gz   pip install http   my package repo SomePackage-1 0 4 zip   So the following command worked for me   pip install    pyfuzzy-0 1 0 tar gz    Hope it can help you

I ve been trying to achieve something really simple and failed miserably  probably I m stupid   Anyway  if you have a script Dockerfile which download a python package zip file  e g  from GitHub  and you then want to install it you can use the file     prefix to install it as shown in the following example     wget https   example com mypackage zip   echo    MYPACKAGE MD5   mypackage zip    md5sum --check -   pip install file     mypackage zip   NOTE  I know you could install the package straight away using pip install https   example com mypackage zip but in my case I wanted to verify the checksum  never paranoid enough  and I failed miserably when trying to use the various options that pip provides the  md5 fragment    It s been surprisingly frustrating to do something so simple directly with pip  I just wanted to pass a checksum and have pip verify that the zip was matching before installing it   I was probably doing something very stupid but in the end I gave up and opted for this  I hope it helps others trying to do something similar

From the installing-packages page you can simply run      pip install  srv pkg mypackage   where  srv pkg mypackage is the directory  containing setup py     Additionally1  you can install it from the archive file      pip install   mypackage-1 0 4 tar gz    1 Although noted in the question  due to its popularity  it is also included

An option --find-links does the job and it works from requirements txt file    You can put package archives in some folder and take the latest one without changing the requirements file  for example requirements      ---requirements txt  ---requirements      ---foo bar-0 1 5-py2 py3-none-any whl      ---foo bar-0 1 6-py2 py3-none-any whl      ---wiz bang-0 7-py2 py3-none-any whl      ---wiz bang-0 8-py2 py3-none-any whl      ---base txt      ---local txt      ---production txt   Now in requirements base txt put   --find-links requirements foo bar wiz bang gt  0 8   A neat way to update proprietary packages  just drop new one in the folder  In this way you can install packages from local folder AND pypi with the same single call  pip install -r requirements production txt  PS  See my cookiecutter-djangopackage fork to see how to split requirements and use folder based requirements organization

Having requirements in requirements txt and egg dir as a directory  you can build your local cache     pip download -r requirements txt -d eggs dir  then  using that  cache  is simple like     pip install -r requirements txt --find-links eggs dir
