“ Rails服务器”创建一个名为“ server”的新应用程序，不启动Rails服务器

Question

I've transferred an older RoR app onto a new workstation and now having issues starting it.

For instance when I attempt to use the "rails server" command it generates a new rails application rather than starting the server.

I did have it running last night but after attempting to use the 'Production' database, apparently the 'rails server -e "production" ' command is obsolete. I therefore tried:

RAILS_ENV=production

And it seems the application was not longer working.

There was also lots of documentation and suggestions to use RVM....which I installed....could that be the cause the 'rails server' command is not starting the server but rather creating a new app?

Answer 1

You should do

RAILS_ENV=production rails s

on rails app dir.

I think your app is on rails 3, with rails 4 installed.

Answer 2

To start the server I had to use: bundle exec rails server what's going on? – paulywill yesterday

Using bundle exec will ensure it uses the version of rails from your Gemfile. This is default behaviour after Rails 3.1 but your app is older than that. – Graeme McLean yesterday
