Distutils provides the register and upload commands for pushing meta-data and distribution files to PyPI, respectively. See Distutils commands for information on these commands.
PyPI lets you submit any number of versions of your distribution to the index. If you alter the meta-data for a particular version, you can submit it again and the index will be updated.
PyPI holds a record for each (name, version) combination submitted. The first user to submit information for a given name is designated the Owner of that name. Changes can be submitted through the register command or through the web interface. Owners can designate other users as Owners or Maintainers. Maintainers can edit the package information, but not designate new Owners or Maintainers.
By default PyPI displays only the newest version of a given package. The web interface lets one change this default behavior and manually select which versions to display and hide.
For each version, PyPI displays a home page. The home page is created from the long_description which can be submitted via the register command. See PyPI package display for more information.
Distutils exposes two commands for submitting package data to PyPI: the register command for submitting meta-data to PyPI and the upload command for submitting distribution files. Both commands read configuration data from a special file called a .pypirc file.
The distutils command register is used to submit your distribution’s meta-data to an index server. It is invoked as follows:
python setup.py register
Distutils will respond with the following prompt:
running register We need to know who you are, so please choose either: 1. use your existing login, 2. register as a new user, 3. have the server generate a new password for you (and email it to you), or 4. quit Your selection [default 1]:
Note: if your username and password are saved locally, you will not see this menu. Also, refer to The .pypirc file for how to store your credentials in a .pypirc file.
If you have not registered with PyPI, then you will need to do so now. You should choose option 2, and enter your details as required. Soon after submitting your details, you will receive an email which will be used to confirm your registration.
Once you are registered, you may choose option 1 from the menu. You will be prompted for your PyPI username and password, and register will then submit your meta-data to the index.
See Additional command options for options to the register command.
The distutils command upload pushes the distribution files to PyPI.
The command is invoked immediately after building one or more distribution files. For example, the command
python setup.py sdist bdist_wininst upload
will cause the source distribution and the Windows installer to be uploaded to PyPI. Note that these will be uploaded even if they are built using an earlier invocation of setup.py, but that only distributions named on the command line for the invocation including the upload command are uploaded.
If a register command was previously called in the same command, and if the password was entered in the prompt, upload will reuse the entered password. This is useful if you do not want to store a password in clear text in a .pypirc file.
You can use the --sign option to tell upload to sign each uploaded file using GPG (GNU Privacy Guard). The gpg program must be available for execution on the system PATH. You can also specify which key to use for signing using the --identity=name option.
See Additional command options for additional options to the upload command.
This section describes options common to both the register and upload commands.
The --repository or -r option lets you specify a PyPI server different from the default. For example:
python setup.py sdist bdist_wininst upload -r https://example.com/pypi
For convenience, a name can be used in place of the URL when the .pypirc file is configured to do so. For example:
python setup.py register -r other
See The .pypirc file for more information on defining alternate servers.
The --show-response option displays the full response text from the PyPI server, which is useful when debugging problems with registering and uploading.
The register and upload commands both check for the existence of a .pypirc file at the location $HOME/.pypirc. If this file exists, the command uses the username, password, and repository URL configured in the file. The format of a .pypirc file is as follows:
[distutils] index-servers = pypi [pypi] repository: <repository-url> username: <username> password: <password>
The distutils section defines a index-servers variable that lists the name of all sections describing a repository.
Each section describing a repository defines three variables:
username, which is the registered username on the PyPI server.
will be prompt to type it when needed.
If you want to define another server a new section can be created and listed in the index-servers variable:
[distutils] index-servers = pypi other [pypi] repository: <repository-url> username: <username> password: <password> [other] repository: https://example.com/pypi username: <username> password: <password>
This allows the register and upload commands to be called with the --repository option as described in Additional command options.
Specifically, you might want to add the PyPI Test Repository to your .pypirc to facilitate testing before doing your first upload to PyPI itself.
The long_description field plays a special role at PyPI. It is used by the server to display a home page for the registered package.
If you use the reStructuredText syntax for this field, PyPI will parse it and display an HTML output for the package home page.
The long_description field can be attached to a text file located in the package:
from distutils.core import setup with open('README.txt') as file: long_description = file.read() setup(name='Distutils', long_description=long_description)
In that case, README.txt is a regular reStructuredText text file located in the root of the package besides setup.py.
To prevent registering broken reStructuredText content, you can use the rst2html program that is provided by the docutils package and check the long_description from the command line:
$ python setup.py --long-description | rst2html.py > output.html
docutils will display a warning if there’s something wrong with your syntax. Because PyPI applies additional checks (e.g. by passing --no-raw to rst2html.py in the command above), being able to run the command above without warnings does not guarantee that PyPI will convert the content successfully.
