“未初始化的常数编码”使用rvm，ruby 1.9.2，bundler和乘客 [英] "uninitialized constant Encoding" using rvm, ruby 1.9.2, bundler and passenger

问题描述

我正在一个私人服务器上运行在Dreamhost上具有root权限。这里有一点关于我的环境和版本。

  $`哪些ruby` -v 
 ruby​​ 1.9.2p180 2011-02-18修订30909）[x86_64-linux] 
 $`哪个bundle` -v 
 Bundler版本1.0.15 
 $`which rails` -v 
 Rails 3.0 .9 
  

除了这个错误，我的rails应用程序运行正常没有问题。但是，当我尝试使用 encode 方法更改编码字符串时：

 code> NoMethodError：foobar的未定义方法encode：String 
  

encode 应该是定义的不是这样！ 如果我尝试在 irb 中找到编码：

  $ irb 
 ruby​​-1.9.2-p180：001>编码
 =>编码
 ruby​​-1.9.2-p180：002> foobar.encode（'utf-8'）
 => foobar
  

但是，如果我尝试通过bundle exec使用rails控制台，未找到编码

  $ bundle exec rails c staging 
加载分段环境Rails 3.0.9）
 ruby​​-1.9.2-p180：001>编码
 NameError：未初始化的常量从/[REDACTED]/shared/bundle/ruby/1.8/gems/aws-s3-0.6.2/lib/aws/s3/extensions.rb:206编码
：来自（irb）的`const_missing'
：1 
 ruby​​-1.9.2-p180：002> foobar.encode（'utf-8'）
 NoMethodError：foobar的undefined方法`encode'：String 
  

显然，安装程序没有正确加载东西，但我不知道在哪里找出来。我在这里缺少什么？

更新6/19/2011

正如Ryan Bigg所指出的，令人好奇的是，宝石的目录路径是 1.8 。但是，运行 bundle exec 表明bundler正在使用正确的ruby和rails版本：

  $ bundle exec ruby​​ 
 /path/to/.rvm/rubies/ruby-1.9.2-p180/bin/ruby 
 $ bundle exec`which ruby​​` -v 
 ruby​​ 1.9.2p180（2011-02-18修订30909）[x86_64-linux] 
 $ bundle exec rails 
 /path/to/shared/bundle/ruby/1.8/bin/rails 
 $ bundle exec`which rails` -v 
 Rails 3.0.9 
  

在这里呀，我只是不知道是什么。

更新6/26/2011

Seamus要求 $ LOAD_PATH ...

更新6/26/2011（稍后）

Seamus要求 Gemfile.lock 和 pp ENV ...在 ENV 输出中，我发现 GEM_PATH 不正确。在我的 staging.rb 环境文件中，我有：

  GEM_HOME = /home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180@[REDACTED]
 GEM_PATH =/home/[REDACTED]/.rvm/gems/ruby-1.9.2- p180 @ [已删除]：/ home / [已删除] /。rvm/gems/ruby-1.9.2-p180@global
  

...显然没有被兑现。我的代码中没有其他地方提到 GEM_HOME 或 GEM_PATH

更新6/27/2011

Seamus问对于 .bundle / config 内容...

解决方案

更新相同的想法（即 GEM_HOME 搞砸了），但更多的建议

您的 GEM_HOME 被搞砸了，可能是因为您的PATH <强>被搞砸了您可以尝试在shell中设置以下环境变量

  $ export PATH = [您当前的路径但是rvm的红宝石1.9在前面] 
  

然后运行

  $ bundle install 
  

t工作，尝试在你的shell中设置这个

  $ export GEM_HOME = [你的宝石1.9宝石首页] 
  

然后重新运行

  $ bundle install 
  

此答案的新想法：使用RVM，bundler不会安装在正确的gemset中宝石安装在不同的红宝石版本

I am at wit's end here and am turning to you all for some help on this f*#$^ encoding issue.

I am running on a private server with root permissions on Dreamhost. Here is a bit about my environment and versions.

$ `which ruby` -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
$ `which bundle` -v
Bundler version 1.0.15
$ `which rails` -v
Rails 3.0.9

Aside from this error, my rails app runs fine without issue. However, when I try to change the encoding a string by using the encode method it:

NoMethodError: undefined method `encode' for "foobar":String

encode should be defined but it is not! Encoding is found if I try in irb:

$ irb
ruby-1.9.2-p180 :001 > Encoding
 => Encoding
ruby-1.9.2-p180 :002 > "foobar".encode('utf-8')
 => "foobar"

But if I try using the rails console through bundle exec, Encoding is not found:

$ bundle exec rails c staging
Loading staging environment (Rails 3.0.9)
ruby-1.9.2-p180 :001 > Encoding
NameError: uninitialized constant Encoding
    from /[REDACTED]/shared/bundle/ruby/1.8/gems/aws-s3-0.6.2/lib/aws/s3/extensions.rb:206:in `const_missing'
    from (irb):1
ruby-1.9.2-p180 :002 > "foobar".encode('utf-8')
    NoMethodError: undefined method `encode' for "foobar":String

Obviously the setup is not loading something correctly but I am not sure where to look to figure it out. What am I missing here?

UPDATE 6/19/2011

As Ryan Bigg pointed out, it is curious that the directory path for the gems is 1.8. However, running bundle exec shows that bundler is using the correct ruby and rails versions:

$ bundle exec which ruby
/path/to/.rvm/rubies/ruby-1.9.2-p180/bin/ruby
$ bundle exec `which ruby` -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]
$ bundle exec which rails
/path/to/shared/bundle/ruby/1.8/bin/rails
$ bundle exec `which rails` -v
Rails 3.0.9

Clearly something is wonky here… I just don't know what.

UPDATE 6/26/2011

Seamus asked for the $LOAD_PATH…

UPDATE 6/26/2011 (later)

Seamus asked for the Gemfile.lock and the pp ENV… In the ENV output, I found that the GEM_PATH was not correct. In my staging.rb environment file, I have:

GEM_HOME = "/home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180@[REDACTED]"
GEM_PATH = "/home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180@[REDACTED]:/home/[REDACTED]/.rvm/gems/ruby-1.9.2-p180@global"

…which is obviously not being honored. Nowhere else in my code is there a mention of GEM_HOME or GEM_PATH

UPDATE 6/27/2011

Seamus asked for the .bundle/config contents…

解决方案

UPDATED same idea (that GEM_HOME is messed up), but more suggestions

Your GEM_HOME is messed up, possibly because your PATH is messed up. You could try setting the following environment variable in your shell

$ export PATH=[your current path but with rvm's ruby 1.9 at the front]

Then run

$ bundle install

If that doesn't work, try also setting this in your shell

$ export GEM_HOME=[your ruby 1.9 gem home]

and then re-run

$ bundle install

New ideas from this answer: Using RVM, bundler does not install in proper gemset when gems are installed in a different ruby version
