does anyone know why the error

"ERROR: While executing gem ... (Errno::EACCES)

Permission denied @ rb_sysopen - C:/Ruby27-x64/lib/ruby/gems/2.7.0/gems/pg-1.2.3-x64-mingw32/lib/2.7/pg_ext.so"

appears while trying to install pg gem in Windows 10?
I tried running gem install pg with admin privileges in command prompt in my application folder, but it throws this error.. I also checked out site https://rubygems.org/gems/pg and there copied how to install pg via command line, and what to include in Gemfile.
Here is my gem file:

I have a large numbers of structs and all of them have responseId: String and there is a property with same name as the value of responseId that contains contactId: String.

• responseId is always non-optional String.
• contactId of inner object is also non-optional String
• all inner objects are optional (at runtime only one of the objects will be non-nil)

Below are two examples:

I have cloned an existing project and trying to run it in my system. Since this is the first time I don't have any Gemfile.lock file in my directory. I tried running bundle install and the following errors occur:

My app works locally, however when I try to deploy to Heroku, I get a Sprockets::FileNotFound: couldn't find file 'angular' with type 'application/javascript' error.

I have tried precompiling with RAILS_ENV=production bundle exec rake assets:precompile and purging my build cache with heroku builds:cache:purge -a findum, but still no luck. I recently migrated from Bower to Yarn– not sure if my asset path is the problem?

Has anyone run into a similar error that they were able to resolve? So many thanks 🙏.

This is my application.js :

I'm trying to build a simple app that is just using a GitHub login for authentication for now. I am using Rails v5.2.3 for the backend, and React for the frontend. I currently have a button in my Root Component that sends an ajax request to my backend. That request will hit an action in my SessionsController that will redirect to the /auth/github route and begin the GitHub auth cycle.

I believe this is step is where I am getting an error.

My browser console gives me this error message:

I have a problem with uploading the images from local as env=production or in heroku. I have spent two days to find a solution, but I couldn't find any.

When I want to add an image locally in production mode, it's appearing in the public folder but cannot use it.

I am uploading images via 'carrierwave' gem. I have downloaded 'figaro' and 'fog-aws' as well. Except uploading an image for user avatar from local, everything is working perfectly. You can check the application that I am trying to complete from here: https://young-atoll-50498.herokuapp.com/?locale=en *you should sign up first for trying to upload image.

UPDATED: Per Michael's suggestion/comment, I am reformatting below display code. I also made the minor fixes on code like rails which was commented out and also not latest. The history of the Gemfile dates back to Michael Hartl's RoR tutorial - I had made an app using it but not touched in last 2 years.

Now I have run bundle update which resulted in a lot of things getting updated which was nice. However at the end it gave me the same error as before - see below pls. Any further advice would be great pls. Thank you.

I picked up a 4 year old project written in Ruby 2.1.3 and Rails 4.1.8.

Very few of the gems were versioned but I've managed to get the project running locally by installing mysql2 0.3.20 as suggested in multiple other threads. Doing this required me to (on MacOS) downgrade openssl and mysql with brew install mysql@57 and brew install openssl@10.

I could then install mysql2 with by passing the correct libraries to it: gem install mysql2 -v 0.3.20 -- --with-mysql-config=/usr/local/opt/mysql@5.7/bin/mysql_config --with-ldflags=-L/usr/local/opt/openssl@1.0/lib --with-cppflags=-I/usr/local/opt/openssl@1.0/include

Everything works locally, all good.

I'm trying to deploy this project with Dokku on a Debian instance. Here's the readout from the push to dokku master including the error thrown when starting the Rails server:

I'm trying to push some modifications of my Ruby on Rails web to Heroku but it says "push rejected". The error comes after "Detecting rake tasks" and here's the message:
