pypm install (package) gives warning: no such package found for requirement

When I try pypm install twisted pypm install morbid pypm install orbited I get

warning: no such package found for requirement "twisted"; try PyPM Index:
http://code.activestate.com/pypm/search:twisted/

warning: no such package found for requirement "morbid"; try PyPM Index:
http://code.activestate.com/pypm/search:morbid/

warning: no such package found for requirement "orbited"; try PyPM Index:
http://code.activestate.com/pypm/search:orbited/

Does anyone know why none of these packages are recognised开发者_运维技巧? Am I doing something obviously wrong?
