PyPI Repositories

The Python Package Index (PyPI) is a repository of open-source Python packages maintained by the Python Software Foundation. See PyPI.

Sonatype Nexus Repository supports proxying PyPi packages and publishing packages to a private index. Use Nexus group repository to expose multiple repositories (proxy, hosted and group) with a single URL.

Before you begin, Install Python and pip. Recent CentOS and Ubuntu distributions commonly include both tools. On macOS and Windows, install a compatible Python release that includes pip. Nexus Repository supports the latest Python 2 and 3 releases and the latest two pip versions.
