babel-register aleary use source-map-support!

I want to use the source map with universal-webpack and babel, but babel-register aleardy use source-map-support, which change the node default error handler. If I import 'source-map-support/register', it will change it twice, which cause the source map output the wrong path.

And I find out when babel-register use source-map-support, it map from the memory running code to the complied file, not from complied file to all source files. How can I generate right source map? @catamphetamine

babel-register use source-map-support by default, and compile code in runtime, which will make node error stack out of order. you can debug in babel-register’s node_modules source-map-support’s source-map-support.js file, where prepareStackTrace will take care of the native prepareStackTrace function and process compiled file to the source file.

but if you disable babel-register and enable source-map-support to the top of server.js, and run the server.js file, then throw new Error('aaa'), the output error stack log will be right. but was wrong when enable babel-register and disable source-map-support.@catamphetamine

I see, so babel-register has its own source maps generated which screws line numbers up. Removing babel-register from the readme then. Thx.
