'rails new --css tailwind' Does not create either bin/dev or Procfile.dev in rails app

in short, creating a new rails app with tailwind css option in my linux terminal (e.g.):

~$ rails new depot --css tailwind --database=postqresql

does not create the necessary files to run the following command:

~/depot$ bin/dev

which when trying to run it at the mean time returns the error below:

bash: bin/dev: No such file or directory

i tried looking for this issue in coding communities, but to no avail

(please bear with me , i'm a newbie at this domain)

Solution

I was working on this same problem this past week. Running Rails 7.2.1 Here are the steps I went through. Since you mentioned you are a newbie at this domain I'm making no assumptions.

Your local environment needs to have Postgres installed and the user setup beforehand.

Tailwind wasn't installed to my app even though I declared it as a an option/variable when creating the app. So I installed it again. - Install Tailwind on Rails
Set the Postgres gem to 1.5.7 in Gemfile as it was failing during installation
```
gem "pg", "1.5.7"
```
Run bundle install to install gems
Create .env in root directory and add database credentials to .env
```
POSTGRES_DEV_PASSWORD=yourpasswordhere
```

Add database env variables to config/database.yml.

development:
      <<: *default
      database: postgres_development_database
      username: your_postgres_username
      password: <%= ENV["POSTGRES_DEV_PASSWORD"] %>
      host: '127.0.0.1'

Run database migrations. bin/rails db:migrate
