【问题描述】：

我花了几天的时间试图修复这个该死的错误，但仍然没有成功，我已经在 *** 和其他网站上尝试了所有我能找到的解决方案。我已经下载并安装了nodejs，只是为了让你知道。

这是错误跟踪：

【问题讨论】：

我尝试添加 ruby​​racer gem，它要求我添加 libv8，即使使用 --with-system-v8 命令我也无法安装

【参考方案1】：

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

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。
