It doesn't produce an exit code so my Travis-CI builds continued to push it to my repos and breaks my stack's updater. Very bad.

Same issue. Downgrading to 2.26.7 isn't great under NodeJS 14+ since it wants fsevents 2 and that version of browser-sync is using fsevents 1.

I'm also seeing this issue and would appreciate a fix. It does seem to be a warning rather than an error, so I am using browsersync OK at version 2.26.10, but it is muddying the tooling console output. Using node v14.3.0.

Hi, my website is using php files, and after I start browser-sync , it shows Cannot GET /.
I typed browser-sync start --server --files="./.jsx, ./.css" to start the browser-sync.
Is it wrong? What should I type?
Thank you very much.

Tried on Windows 10 & OSX
Node v12.18.2
npm v6.14.5

For windows: Error stopped showing when I downgraded to 2.26.10
For OSX: I can't get it to work even with version 2.26.10

When I install version 2.26.7 I get vulernability warning:

  High            Denial of Service                                             

  Package         http-proxy                                                    

  Dependency of   browser-sync [dev]                                            

  Path            browser-sync > http-proxy                                     

  More info       https://npmjs.com/advisories/1486

Is the annoying warning message preferable to this vulernability?

Okay, so it's not giving an error anymore, but it's still not loading my js files or processing angular js. Although when I open index.html without browser-sync, it works. So there's something wrong with my browser-sync command, I imagine? I'm writing "browser-sync start --server --directory --files "*/"" in my directory that contains index.html, app.js and angular.min.js.
Can you figure out why this is happening? @Yesh123456

Hi all, fixed as of [email protected] :)
