I also have this problem. You have to intsall atom-material-ui theme to solution the problem.
中文:我也遇到了这个问题。你应该安装atom-material-ui这个主题来解决上面的问题

[llaolaol]

Same error after installed atom-material-ui

[helloyou2012]

Same error after installed atom-material-ui. But I reinstall activate-power-mode, it is OK.

I've found that if you wanna toggle activate-atom-mode package in “setting”, it fails with
TypeError: Cannot read property 'clearRect' of undefined...
and TypeError: Cannot read property 'classList' of undefined
but if you toggle it in a new file(ctrl+n), it works.... and I've install this package by "npm install" manually cuz somehow I always fail to apm install it.
