未找到Ruby gems，但已安裝

當我嘗試加載Rails控制檯（或加載運行Apache/Passenger的網站）時，出現無法加載已安裝的gem的錯誤：未找到Ruby gems，但已安裝

Missing these required gems: 
    authlogic 
    machinist 

You're running: 
    ruby 1.8.7.249 at /usr/bin/ruby1.8 
    rubygems 1.3.5 at /var/lib/gems/1.8 

Run `rake gems:install` to install the missing gems.

所以，我也跟着安裝寶石的說明如下：

 
> sudo rake gems:install --trace 
(in /home/nblade/vipreblade/src/console) 
DEPRECATION WARNING: Rake tasks in vendor/plugins/delayed_job/tasks, vendor/plugins/easy-fckeditor/tasks, vendor/plugins/jrails/tasks, and vendor/plugins/restful_authentication/tasks are deprecated. Use lib/tasks instead. (called from /var/lib/gems/1.8/gems/rails-2.3.8/lib/tasks/rails.rb:10) 
** Invoke gems:install (first_time) 
** Invoke gems:base (first_time) 
** Execute gems:base 
** Invoke environment (first_time) 
** Execute environment 
** Execute gems:install

它沒有安裝任何東西，所以我檢查我的好措施寶石環境：

我也驗證了寶石安裝：

drwxr-xr-x 7 root root 4096 2010-08-03 12:14 authlogic-2.1.5

drwxr-xr-x 4 root root 4096 2010-08-03 12:14 machinist-1.0.6

所以，很顯然，我做錯了什麼，但我不知道要檢查什麼。有什麼建議麼？

謝謝。

您是否可能安裝了多個版本的Ruby？ – Karl 2010-08-03 21:06:19

這就是我認爲的，所以我仔細檢查了： >其中紅寶石在/ usr/bin中/紅寶石 > LS -al在/ usr/bin中/紅寶石 lrwxrwxrwx 1根根7 2010-07-13 19:54/usr/bin/ruby - > ruby1.0 > ls -al /usr/bin/ruby1.8 -rwxr-xr-x 1 root root 5488 2010-03-19 10:53/usr/bin/ruby1。 8 – 2010-08-03 21:17:11

謝謝！在我的情況下，gem更新之後突然gem env顯示'安裝目錄：/ usr/lib/ruby/gems/1.9.1'，它從/var/lib/gems/1.9.1/gems/更改或突然失蹤。通過軟鏈接進行修補。 'gem1.9.1 list'是空的，我所有的腳本都失敗了，在我安裝了100之前。 – Marcos 2012-03-20 14:46:33

找到它。我忘記了我之前解開了寶石，所以我查看了我的rails項目的供應商/寶石，當然，authlogic和機械師寶石目錄都沒有任何代碼（儘管目錄確實存在幷包含了一個。規格文件）。因此，要解決這個問題我這樣做：

rake gems:unpack:dependencies 
rake gems:build

爲了驗證我做了什麼：

rake gems

現在script/console和Apache /乘客做工精細！

不要忘記接受你自己的回答 – bjg 2010-08-03 22:19:57

我試圖接受它，但它告訴我我必須等幾天。謝謝你的提高，壽。 – 2010-08-04 01:36:49

確實「gem list | grep machinist」列出了什麼？你可以嘗試運行「寶石卸載機械師」，然後「寶石安裝機械師」

2010-08-03 21:04:19

是的，寶石列表顯示了兩個缺失的寶石。我試圖卸載/重新安裝，但沒有幫助。重新安裝後，這裏是我有： > gem list | grep machinist 機械師（1.0.6） >寶石列表| grep authlogic authlogic（2.1.5） – 2010-08-03 21:14:55

未找到Ruby gems，但已安裝
