PyPI CLI Usage

This page describes the CLI commands to search, install, and publish packages after creating and configuring a PyPI repository on Nexus.

Test Your Client Configuration

Use the following commands to validate client configuration before you install or publish packages:

# pip
pip install --dry-run requests --index-url http://example.nexus.com/repository/pypi-all/simple -v

# uv
uv pip install --dry-run requests --index-url http://example.nexus.com/repository/pypi-all/simple -v

# Poetry
poetry add --dry-run requests -vvv

Install and Search PyPI Packages

After you configure your client to connect to Nexus, use one of the following commands to install packages.

Install with pip

To install with pip, run the following command:

pip install <PACKAGE_NAME>

Where <PACKAGE_NAME> is the package you want to install from the configured repository.

Example:

pip install requests

To verify your configuration, run:

pip config list -v

To search available packages from the command line, run:

pip search <PACKAGE_NAME>

Where <PACKAGE_NAME> is the package name or search term.

Example:

pip search example-package

Note

pip search is deprecated and does not work with proxy repositories. You can still search hosted repositories from the command line.
For pip-based installs, point pip to your Nexus repository in pip.conf or pip.ini as described on the Configure PyPI with Nexus page.

Install with uv

To install with uv, run the following command:

uv pip install <PACKAGE_NAME>

Where <PACKAGE_NAME> is the package you want to install from the configured repository.

Example:

uv pip install requests

To sync project dependencies through the configured repository, run:

uv sync --index-url http://<NEXUS_URL>/repository/<REPO_NAME>/simple

Where,

<NEXUS_URL> - Your Nexus instance URL.
<REPO_NAME> - Name of the target repository in Nexus.

Example:

uv sync --index-url http://localhost:8081/repository/pypi-all/simple

Install with Poetry

To install with poetry, run the following command:

poetry add --source <SOURCE_NAME> <PACKAGE_NAME>

Where,

<SOURCE_NAME> - Configured Poetry source name.
<PACKAGE_NAME> - Package you want to add from that source.

Example:

poetry add --source nexus requests

Publish PyPI Packages

After you configure credentials, use one of the following commands to upload packages to a Nexus hosted repository.

Publish with twine

To publish with twine, run the following command:

twine upload -r <REPOSITORY_ALIAS> <FILENAME>

Where,

<REPOSITORY_ALIAS> - Repository alias defined in .pypirc.
<FILENAME> - Package file you want to upload.

Example:

twine upload -r nexus-hosted dist/example_package-1.0.0.tar.gz

Publish with Poetry

Run the following commands to build the package and publish it with poetry.

poetry build
poetry publish -r <REPOSITORY_ALIAS>

Where <REPOSITORY_ALIAS> is the repository alias configured for the target hosted repository.

Example:

poetry build
poetry publish -r nexus-hosted

Publish with uv

uv can be used to install twine, then upload the package through twine.

uv pip install twine
twine upload --repository-url http://<NEXUS_URL>/repository/<REPO_NAME>/ dist/*

Where,

<NEXUS_URL> - Your Nexus instance URL.
<REPO_NAME> - Target hosted repository in Nexus.

Example:

uv pip install twine
twine upload --repository-url http://localhost:8081/repository/pypi-hosted/ dist/*
