Cannot view in browser, and localhost:4000 gives error

This is my cmd log:

So, I tried localhost:4000 (but that’s not the url the cmd says), but this page now gives me a new error:

(also, when I get this error, my cmd automatically gets filled with hundreds of lines of code of .scss. Strange!)

My path to getting vagrant set up seems to be pre-filled with obstacles which I don’t understand :confused: Please help me with this error. Thanks! :slight_smile:

The correct port is 4000 (it’s 3000 inside vagrant and 4000 outside).

Looks like you got a error on Execjs, maybe because you’re on windows - which is strange because vagrant was supposed to solve this.

The bundle install goes fine?

You don’t want to go to That particular IP of a server means “any server”, which means the virtual machine listens to all IPs that belong to a computer (useful as a shortcut meaning if application doesn’t want to specify an IP it listens from), but you cannot access your virtual machine without VirtualBox bridge, which sets localhost port 4000 to redirect to port 3000 of your virtual machine.

You should use localhost:4000 instead of


As I have said before, I have already used that:

but same error.

Yes, I have done bundle install and bundle update both.

That may be your problem.

The Discourse Gemfile and Gemfile.lock files have versions for some gems specified.
Despite what vagrant may be telling you, I recommend you don’t manually upgrade any gems and let Discourse handle the versions.

Also, are you starting it up with
bundle exec rails s -b

Then, as said point your browser to localhost:4000

Unfortunately, I have already run bundle update :frowning: Vagrant was constantly telling me:

You are running an old version of bundler, please upgrade bundler ASAP…

And things weren’t working properly for me so maybe I thought this is the problem so I ran bundle update. Anyway to revert this to get things working properly?

And yes I am using bundle exec rails s -b and localhost:4000

Unfortunately, if there is a way to “undo” or “rollback” I don’t know how.

I had a few false starts, each time getting a bit further. But what I did was uninstall GitHub, VirtualBox, and Vagrant paying more attention to things I might have missed before and trying things a bit different. (and yes, upgrading gems was one thing I tried)

The first “successful” attempt ran painfully slow. I believe it was because I installed everything directly under C and Windows had a security / privilege problem with that. At least I think that was why I had “sharing” problems.
That, and I was opening the shell from the GitHub GUI

Then I upgraded to Windows 10 and everything broke, forcing me to try again.

This last time, which knock wood has been running well, I:

  • installed GitHub - used all defaults

  • installed VirtualBox - used all defaults

  • installed Vagrant - used all defaults

  • instead of putting my “work” under C I put it under

  • I open the shell from the Start menu - GitHub - Git Shell

  • I don’t touch the GitHub or VirtualBox GUI

It takes a bit more effort cd’ing to the work folder, but Windows hasn’t complained yet.

Thanks! :slight_smile: But I am a bit hesitant to try this fix, especially since it involves everything that I did :frowning:
