Hi Chris, I am doing this on Pub Beta 2, and I am getting this error.

configure: error: something wrong with LDFLAGS="-L/Users/pitosalas/.asdf/installs/ruby/3.0.6/lib "

No amount of googling has helped me. Any idea? Thanks!

cable_ready 4.5.0
rails 6.1.4.1
ruby 3.0.2p107

This is a simple example from the basic tutorial (https://www.youtube.com/watch?v=F5hA79vKE_E) I suspect the error I am getting is because either cable_ready or rails evolved a little and created a tiny incompatibility.

When do the broadcast, I get this in the java console:

TypeError: undefined is not a function (near '..operations.forEach...")
- perform - cable readv.is:13
- received  - timeline_channel.js:15
- map
- message
WebSocket connection to 'ws://0.0.0.0:3011/cable' failed: WebSocket is closed due to suspension.

Here it is

It is triggered when in my controller I ask cable ready to:

cable_ready["timeline"].console_log(message: "***** cable ready post created")

[1]:

Which leads to my timeline_channel to:

received(data) {
    console.log("******** Received data:", data.operations)
    if (data.cableReady) CableReady.perform(data.operations)
  }

My interpretation is perform causes this line in cable_ready.js line 13:

  operations.forEach(function (operation) {
    if (!!operation.batch) batches[operation.batch] = batches[operation.batch] ? ++batches[operation.batch] : 1;
  });

Is finding something in the received data that it doesn't like.

That's where my trail ends. Can someone see what I am doing wrong, or tell me what other code you'd like me to include?

What if I have a windows computer and dont want to install ruby on the computer. Can I create a docker environment that has ruby and rails installed and where I do all the development, editing, rails new inside the image. Even run vscode outside and ssh into the image. Is that possible, and do you have a pointer for an article of yours or elsewhere to help me set that up?

COMMENT ADDED: I found the problem. I had a -B in my .railsrc from a long time ago, which told it not to run bundler and from that it decided not to do rails webpacker:install. (I really dislike and continue to be confused by the way webpacker is (not) integrated into rails)

ORIGINAL QUESTION: I guess I must be unique, because I got an error no one has reported. This is on the MacOS beta (latest), and I have everything up to this point installed correctly. I also did an extra bundle command just to be sure. Here's the error:

~/mydev/gorails/myapp (master) rails s

Please run rails webpacker:install Error: No such file or directory @ rb_sysopen - /Users/pitosalas/mydev/gorails/myapp/config/webpacker.yml (RuntimeError)

I'm having trouble following the tutorial. Can you share the source for the example you were showing?

Hey Chris, where's the Slack again?

Thanks. I was following a tutorial (not here) and there were certain details about what layouts/application.erb was supposed to look like and it didn't match. Then I had a problem which I think was due to a bundler version. All that got me thinking... (Btw other than your excellent responses, where would you say is the go-to place to post questions like this? Is it stack overflow? or https://discuss.rubyonrails.org? Or somewhere else?

Starting to teach another semester I like to recommend the latest versions that work correctly and/or are recommended by the maintainers. I can’t find a proper recommendation, and I’ve seen a few glitches with 3.0.0 + 6.1.1. I don’t know if those glitches are my fault or due to my using those packages. What is your recommendation?
