我正在关注 Ruby on Rails 教程，我在第 2 章。当我输入命令时

rails new demo_app

这个错误溢出了。我试过寻找解决方案，但没有一个答案匹配。我尝试卸载/重新安装 railties 和 rails 但仍然遇到相同的错误。

         run  bundle install

有什么建议么？谢谢你。

不是答案，而是解决方案。

所以我放弃并卸载了railsinstaller并重新安装在Z：\目录中。“Program Files”中的空白导致的问题太多了，不止这一个。（尽管我在 RoR 教程中使用的基本教程应用程序似乎没有任何问题。）

在此之后，捆绑安装命令运行良好。我确信还有另一种方法可以引导空间，但我不知道怎么做，而且我认为这不值得麻烦。

我希望这可以帮助别人。我还评论了一些与空间问题相关的答案，所以如果你有其他问题，我的历史可能会有所帮助。
