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
.
constructor
can be installed into the base environment using:
$ conda install 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
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
conda
itself. If you require the ability to useconda
after installation, addconda
to 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
explicitly.
In particular, on Windows this means that if you want the "Anaconda
Prompt", you will have to list
console_shortcut
, as well asmenuinst
. - For Windows builds, add the Anaconda channel
/msys2
to the fileconstructor.yaml
. This provides packages such asm2w64-toolchain
which is a dependency oftheano
. It is best to add/msys2
ashttp://repo.anaconda.com/pkgs/msys2
. - Constructor requires conda >=4.5.0
To build or update README.md
at the root of the repo you'll need jinja2 installed
conda install jinja2
and then run make doc
. Or invoke the script directly with python scripts/make_docs.py
