constructor is a tool which allows constructing an installer for
a collection of conda packages. Basically, it creates an Anaconda-like
installer consisting of conda packages. This tool was previously
proprietary and known as cas-installer.
It is important that the constructor package is installed into the root
conda environment (not to be confused with root user).
The following command ensures that this happens:
$ conda install -n root constructor
Once installed, the constructor command will be available:
$ constructor -h
The constructor command takes an installer specification directory as its
argument. This directory needs to contain a file construct.yaml,
which specifies the name of the installer, the conda channels to
pull packages from, the conda packages included in the installer etc. .
The complete list of keys in this file can be
found in CONSTRUCT.md.
Also, the directory may contain some additional optional files (such as a
license file, and image files for the Windows installer).
An example is located
in examples/maxiconda.
- Constructor does not work with
noarchpackages, all conda packages must be available for the platform you are building the installer for.
