Install Discourse on macOS for development

MarkDoerr · January 11, 2022, 3:44pm

While setting up a new M1 MacBook Air, I was unable to run bundle install successfully, getting this error:

An error occurred while installing openssl (2.2.1), and Bundler cannot continue.

This Mac came pre-installed with OpenSSL1.1 and the script installs OpenSSL3.0 through Homebrew. After uninstalling 3.0, bundle install worked as expected.

Hi @alxndr did you ever find a fix?

nickmoores · January 12, 2022, 8:37pm

Thank you this was helpful! On OSX Big Sur, at this step

I continually run in to:

An error occurred while installing mini_racer (0.6.1), and Bundler cannot continue.

I’ve confirmed my gcc is up to date, and haven’t had any other issues with gemfile or dependencies up to this point. Any ideas?

For more context:

make: *** [mini_racer_extension.o] Error 1

make failed, exit code 2

Hi Mark,

Do you mean simply brew uninstall openssl and then re-run bundle install ? On an M1 mba, bundle install still errors out with the openssl 2.2.1 message after doing so.

[edit] ah, I had to add /opt/homebrew/opt/openssl@1.1/bin to PATH. Let’s see if this works…

[edit2] also had to brew install node for ember-cli. Now it’s working!

jaskaran_Singh · January 20, 2022, 12:46pm

Can you please explain where we need to add this path ? I am facing same issue, details will be very helpful !

schwa · January 20, 2022, 8:21pm

export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"

I also had to mess with the mysql gem to get it to build on ARM. I was using mariadb so it was something like this:

gem install mysql2 -v '0.5.3' -- 
--with-mysql-lib=$(brew --prefix mariadb)/lib 
--with-mysql-dir=$(brew --prefix mariadb) 
--with-mysql-config=$(brew --prefix mariadb)/bin/mysql_config 
--with-mysql-include=$(brew --prefix mariadb)/include

Slim-Kongz · February 6, 2022, 3:29pm

To start the rails server
I used rails server instead of bundle exec rails server
the bundle exec rails server gives me an error.

Could not find ‘xxx gem’ (Even though I have installed the gem…)

What is the difference between bundle exec vs no bundle exec?

Gabriel_Baierle · February 14, 2022, 6:14pm

Have any of you faced this issue while trying the bundle install?

An error occurred while installing openssl (2.2.1), and Bundler cannot continue.

In Gemfile:
  cose was resolved to 1.2.0, which depends on
    openssl-signature_algorithm was resolved to 1.1.1, which depends on
      openssl

and also:

An error occurred while installing mini_racer (0.6.2), and Bundler cannot continue.

Gabriel_Baierle · February 15, 2022, 7:30pm

I don’t know exactly if this was the catch, but I ran this command:

gem update --system

After running it, I relaunched the my terminal, and the bundle install worked fine. Didn’t have any other issues after that, just followed the guide.

Zeshan_Raja · March 15, 2022, 4:13am

Hi! I am currently trying to run bundle exec rake db:create but I keep getting redis related errors, specially the following:
nil versions are discouraged and will be deprecated in Rubygems 4 Discourse requires Redis 6.2.0 or up
I’ve been working on this all weekend and I am just about ready to retire and take up basketweaving. Any help would be really appreciated!

pfaffman · March 16, 2022, 6:30pm

Sorry you’re so stuck.

The “nil versions are discouraged” means that it failed to connect and/or get a version from Redis. So it’s not that the version is wrong, but that it’s not finding it.

Did you install with brew install? (which is in https://raw.githubusercontent.com/techAPJ/install-rails/master/mac that you should have run if you followed these instructions)

I think the thing to do is to go through https://raw.githubusercontent.com/techAPJ/install-rails/master/mac line by line and make sure that stuff worked?

But maybe first, check these things:

Did you do a bundle install before trying to do the bundle exec rake db:migrate? What does ./bin/rake db:migrate do?

Zeshan_Raja · March 16, 2022, 6:55pm

Thank you for replying, Jay.
I have run bundle install within the discourse directory and it ran successfully. However, both commands (bundle exec rake db:migrate and ./bin/rake db:migrate) both show the same nil version error.
I have tried installed via brew and I also had the idea of installing it line by line, but still the same error.
Should I try trashing the directory and starting from scratch?

Kunal_Verma · March 16, 2022, 6:59pm

Hey all, i am actually trying to setup discourse on my local system (MacOs)!

I’ve installed all the necessary packages that are needed & listed here.

Now as I try executing the command bundle exec rails server & try to open http://localhost:3000/ , where the app should work, its not showing any result!

Not able to proceed from here on. Tried a lot of things

These are the logs i get after running the above command:

WARNING: Using `bundle exec` to start the server is unnecessary, and will make startup slower. Use `bin/rails s` or `bin/unicorn`.

pfaffman · March 16, 2022, 7:15pm

Looks like you have a problmem with image Magick.

Also, what is supposed to happen is that this keeps running, Then you’ll also need to do ./bin/ember_cli (I think that’s it) in another terminal and the point your browser to localhost:4200.

Kunal_Verma · March 17, 2022, 10:30am

I agree with your point that this should keep running, but thats not the case here! This command gets executed and then exits!
Also, can you pls elaborate a bit more on how can i fix the image Magick issue here. Not able to understand!

Would i have to install image Margick separately, from here?

lin_turing · March 30, 2022, 1:22pm

On M1 MacBook Pro, i want to running discourse, but when i type

,i can’t access port:4200

Decorbuz · March 30, 2022, 1:52pm

Back in November, I ran into the same issue on my M1 iMac and managed to solve it thanks to a brilliant member here.

nickmoores · April 12, 2022, 8:37pm

Hi, I had the exact same issues you did in your post, and I’ve tried
gem update --system

and re-attempting and I still get

An error occurred while installing openssl (2.2.1), and Bundler cannot
continue.

In Gemfile:
  cose was resolved to 1.2.0, which depends on
    openssl-signature_algorithm was resolved to 1.1.1, which depends on
      openssl

Any other ideas? maybe I’ll try gem update --system one more time?

nickmoores · April 12, 2022, 9:44pm

I’ve been able to update openssl, but how to get Bundler to use the updated openssl and not the old 1.1.1?

alexfowler · April 20, 2022, 4:05am

Hi, I’m trying to setup Discourse on MacOS Catalina (Version 10.15.7) but am encountering an error about no password supplied when I try to run the bundle exec rake db:create.

I had a pre-existing postgres database instance running on my machine prior to my attempted installation of Discourse, I think that could be a factor. How should I resolve this?

Here’s the error stacktrace:
