I have seen some similar issues on heroku, but i am running this locally so I am a bit confuddled.
I am following the Agile Web Development with rails 6 book.
I faced the same issue, I was using the latest version of node v15.2.0 and switched to a lower version of node v14.8.0 and webpacker is working fine.
Reference: [https://github.com/rails/webpacker/issues/2779#issuecomment-727170370]
What I did here simply is comment out line number 9.

I am running a rails application (rails: 4.2 and ruby 2.2.3). I am trying to update my ruby to 2.4.4 and have been able to successfully run bundle install. However, when I start the server and go to the home page of my application, I encounter a unexpected = in the application.html.haml file for this line:
= favicon_link_tag 'favicon.ico'
Has anyone here encountered an error like this?
P.S. if this question has been posted before can someone redirect me to it as I cannot find this problem.

Every thing worked fine for me with Redmine 3.3. Now I wanted to upgrade to 3.4.4 and Redmine is no longer running. I searched the internet but did not find the exact same problem. Similar problems where caused by plugins but I do not have any plugins installed. I use the Passenger Docker image of Redmine.
The logs give me the following error message:

What could that be? I need to upgrade to 3.4 because I want to use a plugin but the plugin requires version 3.4 in use.
It was my fault! I did not copy every new settings file to my mounted config directory.
Recently, I've been working on migrating my Ruby on Rails site, built on passenger, to a different server, and in the process upgrade rails from 2.3.2 to 3.2. I've installed all necessary gems, and I thought configured everything correctly, but when I go to my site, I get a "We're sorry, but something went wrong" message
I checked the production.log and this is the error message I got:

I'm still pretty new to Rails, so I'm currently at a bit of a loss what to do. Any help would be appreciated!
<%= javascript_include_tag :defaults %>
This tag is from Rails versions pre 3.1. Are you sure this is what you want to do?
In newer applications, this line is typically including the application JavaScript file instead:
<%= javascript_include_tag "application" %>
This is made possible due to the Asset Pipeline which you can learn about by reading The Asset Pipeline Guide.
I am using winston/google_visualr to create nice graphs to visualize statistics in my rails application.
It works fine on my locale system, but if I push it to heroku I get something like a token_error. The result is, that it shows only the Heroku page
We're sorry, but something went wrong.
My head section of application.html.erb looks like this
<head>
<title><%= full_title(yield(:title)) %></title>
<script src='http://www.google.com/jsapi'></script>
<%= stylesheet_link_tag "application", :media => "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
This is the heroku log:

It looks like that the external script reference may be the reason. Do you have any idea how to implement this?
The demo implementation of the author of the googlevisualr rails extension on heroku works fine. Is there any configuration settings in heroku I need to consider?
Thanks for your help.
It took me a lot of tries but I found the issue.
The error happens if one of the included JS' has syntax errors, i.e. a missing semicolon.
In my Gemfile I didn't add version numbers to my gem '...'.
I was using the gem 'bootstrap-datepicker-rails' in version '0.6.21' for my development environment.
If you push to heroku all your gems will be installed again, with the newest available version. Since version 0.6.28 is the actual version it was installed on heroku. It may have a syntax error and it caused the above issue. So, it had nothing to do with the line
<script src='http://www.google.com/jsapi'></script>
I just corrected the line in my gemfile to the following and all was working then:
gem 'bootstrap-datepicker-rails', '0.6.21'
I'm having an issue with HAML where it is attempting to write to a read-only filesystem (on a Heroku-deployed app).
I can only write to /tmp and /log. How can I configure HAML to write files to the /tmp directory?
Thanks!

Like Mark commented, I think you mean SASS, not Haml. Here's how to use git commit-hooks to precompile your SASS before deploying to heroku.
EDIT: After full error was posted
Change
= stylesheet_link_tag "reset", "application", "grid", :cache => "base"
to
= stylesheet_link_tag "reset", "application", "grid"
The caching isn't HAML, it's RAILS, and it's doing this on first read.
