"""Scans all reachable rules for dependencies and installs them.
|
||
|
|
Given a set of target rules, all reachable rules will be scanned for
|
||
|
|
dependencies that they require to function (such as external Python libraries,
|
||
|
|
system tools/libraries/etc).
|
||
|
|
|
||
|
|
If the --install option is passed to the command it will attempt to install or
|
||
|
|
update all of the discovered dependencies. The command must be run as root
|
||
|
|
(via sudo) in order for this to work. For dependencies that install locally
|
||
|
|
(such as Node.js modules) they will be placed in the current working directory.
|
||
|
|
|
||
|
|
TODO(benvanik): it'd be nice to support * syntax or some way to say 'everything'
|
||
|
|
|
||
|
|
Example:
|
||
|
|
# Check dependencies and print results for rule :some_rule
|
||
|
|
manage.py depends :some_rule
|
||
|
|
# Install/update all dependencies for rule :some_rule
|
||
|
|
manage.py depends --install :some_rule
