upip library installing error

[makram]

Hi everyone,
I am trying to install a library using upip but it is giving me error.

>>>import upip
>>> upip.install('micropython-umqtt.simple')
"Installing to: /lib/
Error installing 'micropython-umqttsimple': list index out of range, packages may be partially installed"


Can anyone please tell me what I am doing wrong

See the docs. But many of the platforms with network capability (e.g. most ESP8266) have umqtt installed by default.
