Quick Start

terrarium [options] COMMAND [requirements files...]

See terrarium --help for a complete list of options and commands.

Creating a new environment

The following example will create a new virtual environment named env that includes the packages defined in requirements.txt

$ terrarium --target env install requirements.txt

Replacing an existing environment

The following example demonstrates how terrarium can be used to replace an existing activated virtual environment with a different set of packages.

$ terrarium --target env install requirements.txt
$ source env/bin/activate
$ terrarium install other_requirements.txt


The environment that was replaced is renamed to env.bak, and can be restored using terrarium revert.


After installing the other_requirements, it is not necessary to run deactivate or activate to begin using the new environment.
