我花了几天时间试图修复这个该死的错误，但仍然没有成功，我已经尝试了我在 stackoverflow 和其他网站上的所有解决方案。我已经下载并安装了nodejs，只是为了让你知道。

这是错误跟踪：

我最终这样做了，错误消失了！我觉得 RailsInstaller 需要想出一个解决方案，否则像我这样的初学者如果使用 Windows 都将不得不面对这个噩梦

Windows 上的 ExecJS::RuntimeError 试图遵循 ruby​​tutorial

1) 删除 //= require_tree 。/ 忽略问题 - 正如 ColinR 上面所说，这条线不应该首先引起问题。ExecJS 与您系统上的 JavaScript 运行时正常工作存在实际问题，删除此行只是忽略了这一事实。
