Cannot read property 'on' of undefined

[danleechina]

When I run react-native start, it shows the info "Cannot read property 'on' of undefined".
I am confused about this issue. Does anyone has any ideas?

I got this error when I use cnpm install to install dependencies from TAOBAO(淘宝)https://npm.taobao.org/.

you should use npm instead of cnpm.

or just using the alias name

alias cnpm="npm --registry=https://registry.npm.taobao.org \
--cache=$HOME/.npm/.cache/cnpm \
--disturl=https://npm.taobao.org/dist \
--userconfig=$HOME/.cnpmrc"
``

as the package `cnpm` may got something wrong when searching the root path of the react-native.
