在应用程序环境中未更新Ruby版本

Question

I updated ruby to 2.2.2 with rbenv

$ruby -v $ruby 2.2.2p95 (2015-04-13 revision 50295) [x86_64-darwin13]

After I created a new rails application by rails new xxx and then rails server ,

Why the ruby version is still 2.0.0. How to fix this? Thanks

Answer 1

You need to freeze Ruby version in two files:

.ruby-version

2.2.2

This file created automatically if you type rbenv local 2.2.2 . The other file require to lock specific Ruby version is the following:

Gemfile

ruby '2.2.2'
...

Afterwards bundle install will fail in case of different Ruby version set as active.
