exists(dep, force=False)

source code

Test whether a known dependency is installed on the system.

This method allows us to test for individual dependencies without testing all known dependencies. It also ensures that we only test for a dependency once.

Parameters:

dep (string) - The dependency key to test.
force (boolean) - Whether to force the test even if it has already been performed.

testAllDependencies(force=False)

source code

Test for all known dependencies.

Parameters:

force (boolean) - Whether to force the test even if it has already been performed.
