为什么Rails使用错误版本的Ruby？

Question

我有一台带有Ruby 1.9.3和rails 3.2.3的Centos6服务器。我使用RVM。然后我安装了ruby 2.0.0和rails 4.0.0。我用RVM更改了默认的ruby版本。并使用ruby --version确认我然后相应地更改了我的 Gemfile 并根据需要运行bundle install和/或bundle update。一切都很好。然后我运行了service httpd restart，然后导航到我的网站并获得以下内容：

无法启动Web应用程序（Phusion Passenger错误）

我错过了什么？为什么rails试图使用错误版本的ruby？

Answer 1

您需要使用目标Ruby重新编译乘客：

rvm use 2.0.0
passenger_install_apache2_module

使用它给你的输出相应地更新你的apache乘客配置。

Answer 2

如果您已登录服务器

rvm --default use 2.0.0

Answer 3

确定。所以在经过一些搜索之后，我发现在我的httpd.conf文件中，显式设置了旧ruby的路径。所以我改变了路径到新的红宝石路径

然后运行gem install passenger

然后用

安装它

./usr/local/rvm/gems/ruby-2.0.0-p195/gems/passenger-4.0.5/bin/passenger-install-apache2-module

然后service httpd restart现在可以了！
