pypiserver is a minimal PyPI compatible server. It can be used to serve a set of packages and eggs to easy_install or pip.
pypiserver will work with python 2.5, 2.6 and 2.7. Python 3 support has been added with version 0.4.0.
Run the following commands to get your PyPI server up and running:
pip install pypiserver mkdir ~/packages # copy some source packages or eggs to this directory pypi-server -p 8080 ~/packages pip install -i http://localhost:8080/simple/ ...
The git repository contains a ‘pypi-server-standalone.py’ script, which is a single python file ready to be executed without any other dependencies.
Run the following commands to download the script with wget:
wget https://raw.github.com/schmir/pypiserver/standalone/pypi-server-standalone.py chmod +x pypi-server-standalone.py
or with curl:
curl -O https://raw.github.com/schmir/pypiserver/standalone/pypi-server-standalone.py chmod +x pypi-server-standalone.py
The server can then be started with:
Feel free to rename the script and move it into your $PATH.
pypi-server -h will print a detailed usage message:
pypi-server [OPTIONS] [PACKAGES_DIRECTORY] start PyPI compatible package server serving packages from PACKAGES_DIRECTORY. If PACKAGES_DIRECTORY is not given on the command line, it uses the default ~/packages. pypiserver scans this directory recursively for packages. It skips packages and directories starting with a dot. pypi-server understands the following options: -p PORT, --port PORT listen on port PORT (default: 8080) -i INTERFACE, --interface INTERFACE listen on interface INTERFACE (default: 0.0.0.0, any interface) -P PASSWORD_FILE, --passwords PASSWORD_FILE use apache htpasswd file PASSWORD_FILE in order to enable password protected uploads. --disable-fallback disable redirect to real PyPI index for packages not found in the local index --server METHOD use METHOD to run the server. Valid values include paste, cherrypy, twisted, gunicorn, gevent, wsgiref, auto. The default is to use "auto" which chooses one of paste, cherrypy, twisted or wsgiref. -r PACKAGES_DIRECTORY, --root PACKAGES_DIRECTORY [deprecated] serve packages from PACKAGES_DIRECTORY pypi-server -h pypi-server --help show this help message pypi-server --version show pypi-server's version pypi-server -U [OPTIONS] [PACKAGES_DIRECTORY] update packages in PACKAGES_DIRECTORY. This command searches pypi.python.org for updates and shows a pip command line which updates the package. The following additional options can be specified with -U: -x execute the pip commands instead of only showing them -d DOWNLOAD_DIRECTORY download package updates to this directory. The default is to use the directory which contains the latest version of the package to be updated. -u allow updating to unstable version (alpha, beta, rc, dev versions) Visit http://pypi.python.org/pypi/pypiserver for more information.
Always specifying the the pypi url on the command line is a bit cumbersome. Since pypi-server redirects pip/easy_install to the pypi.python.org index if it doesn’t have a requested package, it’s a good idea to configure them to always use your local pypi index.
For pip this can be done by setting the environment variable PIP_INDEX_URL in your .bashrc/.profile/.zshrc:
or by adding the following lines to ~/.pip/pip.conf:
[global] index-url = http://localhost:8080/simple/
For easy_install it can be configured with the following setting in ~/.pydistutils.cfg:
[easy_install] index_url = http://localhost:8080/simple/
pypi-server’s -U option makes it possible to search for updates of available packages. It scans the package directory for available packages and searches on pypi.python.org for updates. Without further options ‘pypi-server -U’ will just print a list of commands which must be run in order to get the latest version of each package. Output looks like:
checking 106 packages for newer version .........u.e...........e..u............. .....e..............................e... .......................... no releases found on pypi for PyXML, Pymacs, mercurial, setuptools # update raven from 1.4.3 to 1.4.4 pip -q install --no-deps -i http://pypi.python.org/simple -d /home/ralf/packages/mirror raven==1.4.4 # update greenlet from 0.3.3 to 0.3.4 pip -q install --no-deps -i http://pypi.python.org/simple -d /home/ralf/packages/mirror greenlet==0.3.4
It first prints for each package a single character after checking the available versions on pypi. A dot means the package is up-to-date, ‘u’ means the package can be updated and ‘e’ means the list of releases on pypi is empty. After that it show a pip command line which can be used to update a one package. Either copy and paste that or run “pypi-server -Ux” in order to really execute those commands. You need to have pip installed for that to work however.
Specifying an additional ‘-u’ option will also allow alpha, beta and release candidates to be downloaded. Without this option these releases won’t be considered.
pypiserver ships with it’s own copy of bottle. It’s possible to use bottle with different WSGI servers. pypiserver chooses any of the following paste, cherrypy, twisted, wsgiref (part of python) if available.
pypiserver relies on the passlib module for parsing apache htpasswd files. You need to install it, when using the -P, –passwords option. The following command will do that:
pip install passlib
If none of the above servers matches your needs, pypiserver also exposes an API to get the internal WSGI app, which you can then run under any WSGI server you like. pypiserver.app has the following interface:
def app(root=None, redirect_to_fallback=True, fallback_url="http://pypi.python.org/simple")
and returns the WSGI application. root is the package directory, redirect_to_fallback specifies wether to redirect to fallback_url when a package is missing.
The following command uses gunicorn to start pypiserver:
gunicorn -w4 'pypiserver:app("/home/ralf/packages")'
In case you’re using apache 2 with mod_wsgi, the following config file (contributed by Thomas Waldmann) can be used:
# An example pypiserver.wsgi for use with apache2 and mod_wsgi, edit as necessary. # # apache virtualhost configuration for mod_wsgi daemon mode: # Alias /robots.txt /srv/yoursite/htdocs/robots.txt # WSGIScriptAlias / /srv/yoursite/cfg/pypiserver.wsgi # WSGIDaemonProcess pypisrv user=pypisrv group=pypisrv processes=1 threads=5 maximum-requests=500 umask=0007 display-name=wsgi-pypisrv inactivity-timeout=300 # WSGIProcessGroup pypisrv PACKAGES = "/srv/yoursite/packages" import pypiserver application = pypiserver.app(PACKAGES, redirect_to_fallback=True)
paste allows to run multiple WSGI applications under different URL paths. Therfor it’s possible to serve different set of packages on different paths.
The following example paste.ini could be used to serve stable and unstable packages on different paths:
[composite:main] use = egg:Paste#urlmap /unstable/ = unstable / = stable [app:stable] use = egg:pypiserver#main root = ~/packages/stable [app:unstable] use = egg:pypiserver#main root = ~/packages/ [server:main] use = egg:gunicorn#main host = 0.0.0.0 port = 9000 workers = 5 accesslog = -
You need to install some more dependencies for this to work, e.g. run:
pip install paste pastedeploy gunicorn pypiserver
The server can then be started with:
Source releases can be downloaded from http://pypi.python.org/pypi/pypiserver
https://github.com/schmir/pypiserver carries a git repository of the in-development version.
git clone https://github.com/schmir/pypiserver.git
to create a copy of the repository, then:
inside the copy to receive the latest version.
pypiserver does not implement the full API as seen on PyPI. It implements just enough to make easy_install and pip install work.
The following limitations are known:
- pypiserver doesn’t implement the XMLRPC interface: pip search will not work.
- pypiserver doesn’t implement the json based ‘/pypi’ interface. pyg uses that and will not work.
Please use github’s bugtracker https://github.com/schmir/pypiserver/issues if you find any other bugs.
