Weird rails error “permission denied: bin/rails” for old rails apps

Question

I\'m getting this error whenever I run rails (or any rails command) _rails_command:2: permission denied: bin/rails ONLY when i\'m inside some

Answer 1

So what worked for me, anyone coming across this issue is to run

bundle exec rake app:update:bin

You'll be given a prompt asking if you want to overwrite? The options here are:

• Y - yes (default one, just press Enter for it)
• n - no (leave current file without changes)
• a - all (apply all changes)
• q - quit
• d - diff
• h - help

I chose a and it seemed to work ok.

Answer 2

The solution for me was:

bundle exec rake rails:update:bin

or just use:

For new rails versions:

 bundle exec rake app:update:bin

For old rails versions:

bundle exec rake rails:update:bin

Answer 3

I have this when I try to use a rails 4.0 version. So when I try to put bundle exec first, like:

bundle exec rake db:migrate

or

bundle exec rails s

work's.

Answer 4

Run

bundle exec rake rails:update:bin

It will update bin/rails and bin/rake files.

Answer 5

In the directory you mentioned is your rails in executable mode. If not you can apply

chmod u+x bin/rails

and make it executable.

Answer 6

I had the same issue and here's what helped me. Open ~/.zshrc and add this

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"
