Hi i just updated to node v8.0.0 and now im can't start the debugger anymore.

To reproduce just enter the following on your cmd or shell:

node --expose_debug_as=v8debug
Program Files\nodejs\node.exe: bad option: --expose_debug_as=v8debug

with v7.10.0 this isn't a problem.

8.x no longer has the "debugger" (it has been deleted from v8), it has the "inspector", so this functionality is gone as is the CLI to expose it.

Consider using the inspector: https://nodejs.org/api/inspector.html

You can use this instead.

const vm = require('vm');
const v8debug = vm.runInDebugContext('Debug');

Note that vm.runInDebugContext is going away soon too, and your best bet would be to move the the inspector API as @sam-github mentioned.

Thanks a lot.

Got here trying to run debug on node v8 in WebStorm.
It worked for me after adding --inspect to node parameters as stated here:
