activeadmin gem中的錯誤

Question

你好我在這裏再次遇到了我的項目中的錯誤。 我想安裝activeadmin寶石，但它顯示錯誤如下。我的rails版本是4.0.0

我期待提供的解決方案，但它也顯示我錯誤。

Updating git://github.com/gregbell/active_admin.git 
fatal: ambiguous argument 'rails4': unknown revision or path not in the working 
tree. 
Use '--' to separate paths from revisions, like this: 
'git <command> [<revision>...] -- [<file>...]' 
Git error: command `git rev-parse rails4` in directory 
C:/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/cache/bundler/git/active_admin-d 
67faab65e9b74efbc8efb4a777a851e9f78b2ca has failed. 
If this error persists you could try removing the cache directory 
'C:/RailsInstaller/Ruby2.0.0/lib/ruby/gems/2.0.0/cache/bundler/git/active_admin- 
d67faab65e9b74efbc8efb4a777a851e9f78b2ca' 

如果我刪除分支名稱就說明我錯誤

Updating git://github.com/gregbell/active_admin.git 
Resolving dependencies... 
Bundler could not find compatible versions for gem "devise": 
In Gemfile: 
activeadmin (>= 0) x86-mingw32 depends on 
    devise (~> 3.2) x86-mingw32 

devise (3.1.1) 

Answer 1

我懷疑你的Gemfile限制你的色器件版本類似~> 3.1.0，這意味着它不會讓你升級到3.2。您在刪除rails4分支時是正確的，因爲master現在是官方的Rails4兼容分支。如果你刪除你的設計版本限制，你應該能夠得到它的工作。

Answer 2

只需要在應用程序啓動時首先進行捆綁。 無需輸入其他寶石文件。

gem 'activeadmin', github: 'gregbell/active_admin' 

在Gemfile和bundle中。它會自動下載你應用程序中所有必需的gem。

只爲信息：

如果有人面臨着類似的問題，而且已經有了寶玉「設計」，沒有版本的Gemfile中，然後首先做一個捆綁安裝，然後嘗試用active_admin

更新的Gemfile
