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

问题:

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 old rails app directory.

In these directories bundle exec rails c command works but rails or even rails -v don't work.

Background: I keep my coding workspace in dropbox folder. Now I recently installed Manjaro and hence all the rails apps which I downloaded back from my previous OS I call them old rails app.

In Short: Rails works fine everywhere except for old rails apps. bundle exec rails c works fine though. Ruby versions which I've tried: 2.0.0 (rvm), 2.1.1(rvm), 2.1.1 (system)

UPDATE: Its working fine in bash, the problem seem to be with oh-my-zsh.

Here is my rvm-info (from zsh):

回答1:

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.



回答2:

Run

bundle exec rake rails:update:bin

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



回答3:

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 -)"


回答4:

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.
