Run a PyPI server with version requirements applied

Project description

PyPIcky is a tiny package that provides a proxy to the PyPI server but with version requirements pre-applied.

Installing

To install:

pip install pypicky

Using

Once installed, create a requirements file (using the same syntax that you would normally use for pip) and then start up PyPIcky by using the pypicky command and passing it the name of the requirements file as a command-line argument:

pypicky requirements.txt

This will start up a small web server, and will print out a line such as:

Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)

You can then call pip with:

pip install --index-url http://127.0.0.1:5000/ astropy

and this will then install the requested packages and all dependencies, ignoring packages excluded by the requirements file.

This can then be used for example with other tools that support PyPI index URLs, such as tox.

Caveats/warnings

If a package is already installed, pip will not try installing it again. This means that if e.g. you try and run pip as described above, but the package you are trying to install (or any of its dependencies) is already installed, no matter how recent the version, it will not be installed again. Therefore, I recommend using pip with the custom index URL inside a clean environment (but you can run the pypicky command inside your regular environment.)
