为两个不同的项目建造两个不同的铁路设施。 它们是不同的铁路。 这里我已安装:
www.un.org/Depts/DGACM/index_spanish.htm
这表明我已经安装了:
<代码>铁路(3.0.0.beta4, 2.3.5)
在我指挥下进行使用2.3.5的部署时,我发现以下错误:
Missing the Rails 2.3.5 gem. Please `gem install -v=2.3.5 rails`, update your
RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do
have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.
尽管我已经安装了铁路,但它没有找到正确的铁路版本。 解决这一问题的短期和长期解决办法是什么?
我建议您RVM。 这使你能够在同一机器上拥有不同的废墟/地毯。
长期解决办法是研究rvm,特别是gemset 特征使得不同项目的地版甚至瓦卢版本难以分开。
短期解决办法可以是,在需要铁路之前的某个地方,在你的boot子档案中增加以下线:
gem rails, "2.3.5"
否则,你会想到最新版本。
As others have noted, rvm is one way to solve this problem. The other is to use bundler, which involves some setup in your application and potentially requiring you to use bundle exec command everywhere you want to run conflicting versions of a command (eg cucumber)
