尽管安装了宝石，仍然无法找到宝石 [英] gem which cannot find gem despite it being installed

问题描述

我已经构建了我的第一个gem，但我似乎无法正确安装它。我可以发出命令：

pre $ sudo gem install ceilingfish -toto
$ b $ p

产生输出

 成功安装了ceilingfish-toto-0.3。 6 
 1 gem installed 
  

但是当我输入 gem which ceilingfish-TOTO 。我得到输出

 无法找到ruby库文件或共享库ceilingfish-toto 
  

这非常奇怪，因为如果我去看看我的gems文件夹，我可以看到所有安装的文件

 ＃ls -l /opt/local/lib/ruby/gems/1.8/gems/ceilingfish-toto-0.3.6/

有谁知道可能导致这种情况的原因？我认为这是抱怨，因为宝石名称中有一个连字符。你可以在这里看到gemspec http://github.com/ceilingfish/toto

解决方案

gem哪些ceilingfish-toto 通过gem require路径查找名为ceilingfish-toto的文件.RB。由于没有一个，它什么都没有返回。你的工作是 gem which toto ，但是因为 lib / 不包含在你的gem spec中，所以lib文件未安装，因此它不存在。

重新运行 rake gemspec 可能会解决此问题。 p>

另外，您可以使用 gem list ceilingfish-toto 来检查是否安装了gem，告诉你它已经安装，不管它有什么文件（它也会列出安装的版本）。

I've built my first gem but I don't seem to be able to get it to install correctly. I can issue the command

sudo gem install ceilingfish-toto

Which produces the output

Successfully installed ceilingfish-toto-0.3.6
1 gem installed

But when I then type gem which ceilingfish-toto. I get the output

Can't find ruby library file or shared library ceilingfish-toto

Which is very strange because if I go and look in my gems folder I can see all the files installed there

# ls -l /opt/local/lib/ruby/gems/1.8/gems/ceilingfish-toto-0.3.6/
total 48

Does anyone know what could cause this? I think it's complaining because there is a hyphen in the gem name. You can see the gemspec here http://github.com/ceilingfish/toto

解决方案

gem which ceilingfish-toto looks through the gem require path for a file named ceilingfish-toto.rb. Since there isn't one, it returns nothing. What would work for you is gem which toto, but since lib/ is not included in your gem spec, the lib files are not installed, so it doesn't exist.

Rerunning rake gemspec might fix the problem.

As an aside, you can check whether a gem is installed by its name by using gem list ceilingfish-toto which should show you it is installed, regardless of the files it has(it will also list the versions installed).
