问题描述

我在尝试安装 ruby​​ 和 rails 时遇到了许多问题.清除以前安装的版本后，我已经尝试了没有和现在.

尝试运行gem install rdiscount --platform=ruby"时出现以下错误:

我已经按照指示运行了 DevKit 安装，它似乎可以工作.Rails 以前可以工作，但现在不行.有人对如何使这项工作有任何建议吗?还是卸载重试的情况?

谢谢

解决方案

您似乎将 Ruby(与 DevKit 一起?)安装在一个带有空格的目录中.

正如Ruby自己的安装程序中所指出的，不推荐带空格的路径(这就是为什么默认为C:\Ruby193

DevKit 的编译器 GCC 的路径有空格有问题，所以 DevKit 的安装也建议放在没有空格的路径(例如 C:\DevKit)

RubyInstaller 和 DevKit 安装说明页面中都提到了所有这些>

I am having a number of issues when trying to install ruby and rails. I have tried both without and now after clearing the previous installed versions.

When trying to run "gem install rdiscount --platform=ruby" I get the following error:

C:\Windows\system32>gem install rdiscount --platform=ruby

I have run the DevKit installation as indicated and it seems to work. Rails was previously working but now is not. Anybody have any suggestions on how to get this working? Or is it a case of uninstall and try over again?

Thanks

Paul

解决方案

Seems you installed Ruby (along the DevKit?) inside a directory with spaces.

As indicated during Ruby own installer, path with spaces are not recommended (that is why default is C:\Ruby193

GCC, the compiler that is part of DevKit, has problems with path with spaces, so installation of DevKit is also recommended to be placed in a path without spaces (e.g. C:\DevKit)

All this is mentioned in both RubyInstaller and DevKit installation instructions page
