Instance Method Details
#alien(gems = []) ⇒ Object
Checks the gem directory for the following potential inconsistencies/problems:
-
Checksum gem itself
-
For each file in each gem, check consistency of installed versions
-
Check for files that aren’t part of the gem but are in the gems directory
-
1 cache - 1 spec - 1 directory.
returns a hash of ErrorData objects, keyed on the problem gem’s name. – TODO needs further cleanup
