更新說明

New /config/index.js options (#975)

dev:
autoOpenBrowser: Wether to open a new browser tab whenever the dev server starts.
useEslint: Wether to use eslint-loader in webpack. Some people might only want to use eslint in their IDE, so the loader can be deactivated here.
showEslintErrorsInOverlay: if using eslint-loader, this option allows to switch of the eslint errors in the error overlay shown in the browser. the errors still appear in the console & terminal, but don't break the workflow in the browser anymore.
notifyOnErrors: will show OS notifications whenever a build fails. Useful when your builds take some time
poll: enables polling mode for webpack's file-change watcher. The default mode doesn't work in some environments, like dropbox folders, Vagrant etc. so switching to polling can fix this.
you can now change sourcemap-related options for the dev and prod builds in the config file.

config/index.js中，把a(bǔ)utoOpenBrowser改成true，就能自動打瀏覽器了，親測可用。

我也遇到這個問題，真坑爹，現(xiàn)在想寫服務(wù)端也寫不了，自己寫又會出很多問題
