单独乘客使用错误的红宝石版本？

Question

Hello im using rails 4 with rvm - ruby verison 2.0. But when i try to start passenger (stand alone) im getting syntax-errors.

It tells me:

Ruby interpreter command
/usr/bin/ruby1.8

How can i change it to the rvm 2.0 version?

Answer 1

you need to use ruby first:

rvm use ruby

it might display additional instructions - make sure to read them

Answer 2

I had the same problem: passenger standalone uses nginx, and after upgrading my app to use ruby 2.1.1 (specified in the .ruby-version), I saw similar errors.

On my production server, I know where the nginx configuration lives, so I could fix the path to the ruby interpreter.

However on the standalone setup I couldn't find it in less a minute, so I did a gem uninstall passenger followed by gem install passenger to have it recompile nginx.

Now it works, at least until the next ruby interpreter bump.
