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
As of version 1.3.0,
constructor may be installed into any conda
$ conda install constructor
Once installed, the constructor command will be available:
$ constructor -h
constructor command takes an installer specification directory as its
argument. This directory needs to contain a file
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
- Constructor does not work with
noarch-Python packages. All conda packages must be available for the platform you are building the installer for.
- An installer created by constructor does not need to include
condaitself. If you require the ability to use
condaafter installation, add
condato the package list.
- An installer created by constructor is not the same as Miniconda. All
packages you want to include in the installer need to be listed
In particular, on Windows this means that if you want the "Anaconda
Prompt", you will have to list
console_shortcut, as well as
- For Windows builds, add the Continuum channels
/msys2to the file
constructor.yaml. This provides packages such as
m2w64-toolchainwhich is a dependency of
theano. It is best to add
