when I tried to start a server with webpack-dev-server, an error has occurred。
so I go to index.ts,and look line32. It is just a 'import'
I debug when the error happen again
when I print on Devtool, I found it's because 'I[g]' didn't exist. so how can i find the lost module and resolve this problem?
ps：when I start a server with Nginx after build, it can work right.
