My ruby ​​version is 2.3.0, my mysql version is 8.0.23, my mysql2 version is 0.5.3, my rails version is 5.0.7.2, and my Xcode version is 12.5.

I use macOS Big Sur(version 11.4) and the text editor "Atom".

I'm planning to release my Rails application with the URL of HEROKU(example. https://[My APP Name].herokuapp.com).

I ran the following command.

$ heroku open

The following error occured.

An unhandled lowlevel error occurred. The application logs may have details.

I ran the following command.

$ heroku logs

#<RuntimeError: Missing
 `secret_key_base` for 'production' environment, set this value in `
config/secrets.yml`>

My config/secrets.yml file is something like belows.

production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

I edited my config/secrets.yml file as below.

production:
  secret_key_base: <%= ENV["secret_key_base"] %>

I deleted two environment variables as below with this command: $ heroku config:unset [ENVIRONMENT VARIABLE NAME].

$ heroku config:unset DATABASE_USERNAME=****

$ heroku config:unset DATABASE_PASSWORD=GENERATED_CODE

I deleted the environment variable SECRET_KEY_BASE in the vim editor of /etc/profile , using the following command.

$ vi /etc/profile

I saved the vim editor of /etc/profile to end it with the two below commands.

:w !sudo tee %

:q!

I deleted the environment variable SECRET_KEY_BASE, using the following command.

$ vi ~/.bash_profile

I saved .bash_profile ,using Esc and then ":x" and Enter.

I ran the following command.

$ bundle exec rake secret

bash: /usr/local/bin/bundle: /System/Library/Frameworks/Ruby.framework/Versions/2.3/
usr/bin/ruby: bad interpreter: No such file or directory

I ran the following command.

$ sed -i 's/\r//' usr/local/bin/bundle

sed: 1: "usr/local/bin/bundle": invalid command code u

I ran the following command.

$ /usr/local/bin/bundle

bash: /usr/local/bin/bundle: /System/Library/Frameworks/Ruby.framework/Versions/2.3/
usr/bin/ruby: bad interpreter: No such file or directory

Below are the output of gem env, which bundle and which ruby.

$ gem env

$ which bundle

/usr/local/bin/bundle

$ which ruby

/usr/bin/ruby

I installed the ruby version "2.3.0" as below ,because bundle seems to call "2.3".

$ rbenv install 2.3.0

I verified that the ruby version "2.3.0" is installed and the current ruby version is "2.3.0".

$ rbenv local 2.3.0

$ rbenv rehash

$ rbenv versions
  
  system
* 2.3.0

$ rbenv global 2.3.0

$ rbenv rehash

$ rbenv versions

  system

But the ruby current version is "2.6.3" when used the below command.

$ ruby -v

I ran the following command.

$ bundle exec rake secret

bash: /usr/local/bin/bundle: /System/Library/Frameworks/Ruby.framework/Versions/2.3/
usr/bin/ruby: bad interpreter: No such file or directory

Why can't I execute $ bundle exec rake secret? And why are there the multiple current ruby versions "2.3.0","2.6.3"?

The error "bad interpreter: No such file or directory" occured.

  • Can you share the output of `gem env`, `which bundle` and `which ruby` please ? – Sumak Aug 13 '21 at 08:36
  • It looks like you're trying to use Linux-style `sed` commands on macOS, which is just different enough to be confusing. First, you need to use an explicit empty arg after `-i` (that is `sed -i '' ...`; see [here](https://stackoverflow.com/questions/5694228)), and also it won't interpret `\r` as a carriage return. Also, I'd take a look at `/usr/local/bin/bundle` (note: the leading `/` is *required* for that path to work) and see what it actually contains before blindly trying to fix it. What is its actual shebang line? Does it contain carriage returns? – Gordon Davisson Aug 13 '21 at 09:07
  • @Marchan4 : The error message looks like a missing slash in a #! line, or you have a relative directory in your PATH. What is the first line of `/usr/bin/bundle` and the value of $PATH? – user1934428 Aug 13 '21 at 09:12
  • You'll want to follow the previous advice and see what `which bundle` and `which ruby` returns, but it looks like you may not be using a ruby version manager. Highly suggested for macOS (rvm, rbenv, chruby, or asdf are all fine) – Jay Dorsey Aug 15 '21 at 04:02
