当我在生产环境中部署我的ror应用程序时，出现以下错误

Question

在`gem_original_require'中：没有要加载的文件-haml（MissingSourceFile）

但是这个宝石已经装好了

我也有此路径的插件：-/ home / techvant / rails_app / techease / vendor / plugins / haml / init.rb

此初始化文件具有以下代码：-

begin
     require File.join(File.dirname(__FILE__), 'lib', 'haml') # From here
   rescue LoadError
     require 'haml' # From gem
end

我需要解决的错误，请帮忙。

以下是错误跟踪。

Answer 1

由于haml是一颗宝石，我将其放在environment.rb中：

config.gem 'haml'

然后，解压缩并将其添加到仓库中：

rake gems:install
rake gems:unpack

最后，删除已有的haml插件引用。

Answer 2

尝试：

宝石更新轨道

...在服务器上，而不是您的开发机器上

Answer 3

您可以尝试解开gems的包装，使它们位于rails应用程序目录中，这将使您的rails应用程序不再依赖于系统中的本地gems。 干杯！

Answer 4

我在这个问题上也有很多麻烦。 这是我最终采取的解决步骤。

首先，安装gem。

放

config.gem 'haml' 

在您的environment.rb文件中。 实际上，我不得不将其放在我的环境/development.rb和环境/production.rb（等等）中，因为它抱怨不知道rails_env。 这不是最佳选择，但确实可行。 然后跑

rake gems:install

然后

mkdir -p /vendor/plugins/haml
cp vendor/gems/haml-2.2.0/init.rb /vendor/plugins/haml/init.rb

然后重新启动Rails服务器。
