Can't get the Chrome console to show the error

In the Gulp Basics "Source maps for JavaScript too" video, we deliberately introduce an error into one of the js files - but I cannot ever see the error in the console in the dev tools in Chrome... The erroneous code line is definitely in the app.js file, as I can see by looking at the script via the Chrome dev tools... What have I forgotten?

If the created bug is in the code and doesn't show in the dev tools, does it show in the command line?

Perform a hard reload on the window. right click the refresh symbol with your dev console open in chrome.

Kind of strange because this server is running locally, but I actually needed to clear my cache, an older version of the file was loading (meaning "var foo = bar" was not in the file)

This comes up more often than you'd think. Racking your brain trying to figure out why your new style or new script didn't load.

Clearing cache manually works but for Chrome I found you can hit Ctrl+Shift+r to do a force reload of the page that doesn't use any cached resources.

if errors aren't showing in chrome dev tools we're all in a lot of trouble :), try just adding 

var elephant = lion;

as long as those variable don't already exist it will throw errors, also make sure you have the console tab selected in dev tools.

Had the same problem. Athough mine was caused by gulp-concat not being installed during npm install. The solution was to re-install gulp-concat for the local dev environment npm install gulp-concat --save-dev

Same here. I can't see the error by the browser, but it appears in git bash after running "gulp concatScripts".

..\gulpfile.js:39
var foo = bar;

its really weird that it doesn't work and show the error for me too . even though i hard reloaded my page plus cleared cache and hard reloaded too ( by right clicking on the refresh button and choosing the option for it! ) its weird.

when i change my src="app.min.js" to src="app.js", it shows me the correct location of the error as shown in the video. i dunno it's right or not but i hope this helps.
