javascript - Uncaught TypeError: Cannot read property 'prototype' of undefined (inherits_browser.js) -


after porting our app newer version of create-react-app following error started occurring:

enter image description here

seems reffering inherits_browser.js coming npm module can't pinpoint. line error refers in file ctor.prototype = object.create(superctor.prototype, , seems used webpack somehow.

has experienced issue before / can suggest problematic areas can occur in?

edit

digging deeper issue seems coming file (cipherbase.js)

enter image description here

i had exact problem today. guess had outdated package in project's node_modules folder, because removing , reinstalling fixed problem.

rm -rf node_modules dist npm install webpack --config ./webpack_prod.config.js

notice in case webpack installed locally devdependency. doing rm -rf node_modules , npm install reinstalled webpack , dependencies.

for reference, i'm running webpack 2.2.1, node.js 7.7.4 , npm 4.1.2.

Retrieving ETA (estimated time of arrival) with Google Distance Matrix API and public transit as transport mode -

Image
is possible retrieve eta google's distancematrix api (or alternative api). fyi, eta different duration, when using public transport. following example clarify request. when leave on friday @ 8.15 i'll able catch train @ 8.30 , arrive @ 9.00 am. google says duration 30 minutes. however, when leave on saturday @ 8.15 i'll able catch first train @ 9.00 , arrive @ 9.30 am. google still says duration 30 minutes, means ignore delay. google map supports functionality there api around giving me eta instead of duration. can see, distance-matrix' response no good. clarifying question little. eta estimated time of arrival , it's clear user wants know entire duration of transport (including waiting time public transport).
