How to force Rails to use gem of version X

Question

I have a rails app with the config/environment.rb line

config.gem 'authlogic', :version => '2.1.2'

The system gem for authlogic is 2.1.4 The one in my GEM_PATH is 2.1.2

No matter what I try, Rails is only using the 2.1.4 version, which is a problem. How to force rails to use 2.1.2?

Thanks

Answer 1

我建议使用Bundler

Answer 2

i've made a test here, included the gem authlogic, choose to use the 2.1.3 version, and the application ran without problems.

then i've uninstalled the gem (gem uninstall authlogic -v=2.1.3), and my application didn't ran anymore, normal behavior (i'm using rails 2.3.8 for this test)

you could try uninstalling and then installing the gem again

Answer 3

为安全起见，请卸载2.1.4版本，冻结2.1.2，然后再卸载2.1.2。

Answer 4

Unpack the gems into your rails app. This'll also help in deployment.

rake gems:unpack

Answer 5

系统管理员重新安装了一些宝石，所有问题都消失了。
