Question

安装了rubyinstaller-1.8.7-p358.exe，然后尝试安装jammit，但无法识别config.gem命令。有趣的是，我的驱动器上没有名为 environment.rb 的文件。

我也从未使用过红宝石：D

H:\>config.gem "jammit"
'config.gem' is not recognized as an internal or external command,
operable program or batch file.

首先，您需要先创建一个Rails应用程序：

将gem添加到初始化程序内部的Rails'environment.rb： config.gem“jammit”

config.gem不是命令rahter，它是environment.rb文件中的条目。

要创建rails应用程序，请转到源文件夹并执行：

rails new <app_name> # replace <app_name> with whatever you want to call your app

它将在一个文件夹中创建一个准确的rails应用程序，其中包含您为该应用程序选择的名称。在该文件夹中，您将找到一个配置文件夹，在该文件夹中，您将看到'environment.rb`

Ruby on Rails安装：config.gem无法识别
