Question

我正在尝试在Windows 7 32系统上安装json ruby gem。

本地环境详情

D:\Environment\DevKit32Ruby200>gem -v
2.0.14

D:\Environment\DevKit32Ruby200>ruby -v
ruby 2.0.0p451 (2014-02-24) [i386-mingw32]

D:\Environment\DevKit32Ruby200>rails -v
Rails 4.0.4

我已经尝试过以下内容

使用
将系统ruby gems版本降级到2.3.0
```
gem update --system 2.3.0
```

我已经正确设置了devkit并手动在config.yml文件中添加了正确的ruby目录路径。

D:\Environment\DevKit32Ruby200>ruby dk.rb init

 Initialization complete! Please review and modify the auto-generated
 'config.yml' file to ensure it contains the root directories to all
 of the installed Rubies you want enhanced by the DevKit.

D:\Environment\DevKit32Ruby200>ruby dk.rb install --force
    [WARN] Updating (with backup) existing gem override for                            'D:/Environment/ruby200new'
   [WARN] Updating (with backup) DevKit helper library for 'D:/Environment/ruby200new'

我也试过把platform = ruby

gem install json --platform=ruby --verbose

安装json时遇到的错误如下：

D:\Environment\DevKit32Ruby200>gem install json
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing json:
        ERROR: Failed to build gem native extension.

此问题已标记了10个问题但未解决。请帮助我确定丢失的内容以及错误发生的原因。

Answer 1

i386-mingw32是一大堆痛苦，永远不会得到完全支持，当我在Windows上度过时，我曾经使用安装了ubuntu的VirtualBox VM与Windows主机共享一个文件夹。我会在windows中使用netbeans编辑文件并在putty中运行代码，VM基本上是无头的。

我实际上通过这种方式做了很多真正的工作。如果你想做一个＆＃34; Hello World＆＃34; rails app - OK - 祝你好运。如https://c9.io/等在线开发环境怎么样？

但是如果你想工作，不仅仅是玩游戏，至少可以使用Ubuntu VM，或者最好在Ubuntu / MacOS中工作。

试试这个：

为什么不从rubygems.org下载json .gem文件并使用命令直接安装

gem install json-x.x.x.gem

错误：无法构建gem原生扩展Windows 7 32位
