在 Windows 中安装 Ruby Gem

Installing Ruby Gem in Windows

提问by user2797743

I'm new to ruby. I tried to install GEM on my PC by following the steps given in the site http://rubygems.org/pages/download.

我是红宝石的新手。我尝试按照网站http://rubygems.org/pages/download 中给出的步骤在我的 PC 上安装 GEM 。

I downloaded the package from the mention site and changed the directory to the directory in which the setup resides and tried to run setup using the command,

我从提及站点下载了包并将目录更改为安装程序所在的目录并尝试使用命令运行安装程序，

setup.rb in command prompt.

命令提示符中的 setup.rb。

but I get a window pop up that says "Windows can't open this file" and prompts me to select a program to open this file.

但是我弹出一个窗口，上面写着“Windows 无法打开这个文件”，并提示我选择一个程序来打开这个文件。

What should I do now? Let me know, if I do something wrong..

我现在该怎么办？让我知道，如果我做错了什么..

To setup you Ruby development environment on Windows:

在 Windows 上设置 Ruby 开发环境：

1. Install Ruby via RubyInstaller: http://rubyinstaller.org/downloads/

2. Check your ruby version: Start - Run - type in cmdto open a windows console

3. Type in ruby -v
4. You will get something like that: ruby 2.0.0p353 (2013-11-22) [i386-mingw32]

1. 通过 RubyInstaller 安装 Ruby：http://rubyinstaller.org/downloads/

2. 检查您的 ruby​​ 版本：开始 - 运行 - 输入cmd以打开 Windows 控制台

3. 输入 ruby -v
4. 你会得到这样的东西： ruby 2.0.0p353 (2013-11-22) [i386-mingw32]

For Ruby 2.4 or later, run the extra installation at the end to install the DevelopmentKit. If you forgot to do that, run ridk installin your windows console to install it.

对于 Ruby 2.4 或更高版本，最后运行额外的安装来安装 DevelopmentKit。如果您忘记这样做，请ridk install在您的 Windows 控制台中运行以安装它。

For earlier versions:

对于早期版本：

1. Download and install DevelopmentKit from the same download page as Ruby Installer. Choose an ?exe file corresponding to your environment (32 bits or 64 bits and working with your version of Ruby).
2. Follow the installation instructions for DevelopmentKit described at: https://github.com/oneclick/rubyinstaller/wiki/Development-Kit#installation-instructions. Adapt it for Windows.
3. After installing DevelopmentKit you can install all needed gems by just running from the command prompt (windows console or terminal): gem install {gem name}. For example, to install rails, just run gem install rails.

5. 从与 Ruby 安装程序相同的下载页面下载并安装 DevelopmentKit。选择与您的环境（32 位或 64 位并使用您的 Ruby 版本）相对应的 ?exe 文件。
6. 按照以下位置描述的 DevelopmentKit 安装说明进行操作：https: //github.com/oneclick/rubyinstaller/wiki/Development-Kit#installation-instructions。使其适用于 Windows。
7. 安装 DevelopmentKit 后，您只需从命令提示符（Windows 控制台或终端）运行即可安装所有需要的 gem：gem install {gem name}. 例如，要安装 rails，只需运行gem install rails.

Hope this helps.

希望这可以帮助。

Installing Ruby

安装 Ruby

Go to http://rubyinstaller.org/downloads/

转至http://rubyinstaller.org/downloads/

Make sure that you check "Add ruby ... to your PATH".

确保选中“将 ruby​​ ... 添加到您的路径”​​。

Now you can use "ruby" in your "cmd".

现在您可以在“cmd”中使用“ruby”。

If you installed ruby 1.9.3 I expect that the ruby is downloaded in C:\Ruby193.

如果您安装了 ruby​​ 1.9.3，我希望 ruby​​ 以C:\Ruby193.

Installing Gem

安装 Gem

install Development Kitin rubyinstaller. Make new folder such as C:\RubyDevKitand unzip.

在 ruby​​installer 中安装开发工具包。制作新文件夹，例如C:\RubyDevKit并解压缩。

Go to the devkit directory and type ruby dk.rb initto generate config.yml.

转到 devkit 目录并键入ruby dk.rb init以生成config.yml.

If you installed devkit for 1.9.3, I expect that the config.ymlwill be written as C:\Ruby193.

如果你为 1.9.3 安装了 devkit，我希望它config.yml会被写成C:\Ruby193.

If not, please correct path to your ruby folders.

如果没有，请更正 ruby​​ 文件夹的路径。

After reviewing the config.yml, you can finally type ruby dk.rb install.

查看之后config.yml，您终于可以键入ruby dk.rb install.

Now you can use "gem" in your "cmd". It's done!

现在您可以在“cmd”中使用“gem”。完成！

Another way is to let chocolateymanage your ruby package (and any other package), that way you won't have to put ruby in your path manually:

另一种方法是让Chocolatey管理您的 ruby​​ 包（和任何其他包），这样您就不必手动将 ruby​​ 放在您的路径中：

Install chocolateyfirst by opening your favourite command prompt and executing:

首先通过打开您最喜欢的命令提示符并执行来安装Chocolatey：

@powershell -NoProfile -ExecutionPolicy unrestricted -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%systemdrive%\chocolatey\bin

then all you need to do is type

然后你需要做的就是输入

cinst ruby

In your command prompt and the package installs.

在您的命令提示符和软件包安装中。

Using a package manager provides overall more control, I'd recommend this for every package that can be installed via chocolatey.

使用包管理器提供了更多的总体控制，我建议每个可以通过巧克力安装的包都使用它。

Check that ruby interpreter is already installed and try "ruby setup.rb" in command prompt.

检查 ruby​​ 解释器是否已经安装并在命令提示符下尝试“ruby setup.rb”。
