Error on Fresh install: MiniRacer::RuntimeError: ReferenceError: setTimeout is not defined

Installation

For the life of me I can’t get it to install. Everything is fine. But when I try to run migrations I get

Already referenced here: Beginners Guide to Install Discourse on macOS for Development but giving it its own special issue.

Not doing anything special I can think of. I bundle install configure the database and that’s about it.

Any help or pointers in resolving this would be much appreciated.

Do you have any plugins installed?

3

None. This is a fresh initial clean install with nothing at all.

4

OK Now I understand what happens. This is because of a bundle update. Using the original Gemfile.lock this behaviour does not appear.

I will try to track down which updated Gem breaks this so it can be expressed in the version constraints in the Gemfile.

I have the same error with Discourse 2.
For now, I use git reset --hard v1.9.1 as a workaround.

OK nailed it down.

locking down :
gem 'pg', '~> 0.21.0'
gem 'ember-source', '2.13.3'

should allow you to run bundle update and not die. Opening a pull request.

Wait I totally get the need to lock ember, but why pg?

As far as I can see PG seems to blow-up as well.
A bundle update here is going to jump very far :

-    pg (0.21.0)
+    pg (1.0.0)

Getting :slight_smile:

That not as big as it looks. 1.0.0 was the next release after 0.21.0. They bumped the major version because it dropped support for Ruby < 2.0 and PostgreSQL < 9.2.

Yup, I saw that after. Big or small jump … it still breaks. See error message above…

Yeah we got to get this fixed, not working on latest pg is a problem.

This does not seem to be you … but upstream.

So for the moment … just freeze the version and wait for open source to do its magic :slight_smile:
