Question

我有一个相当不幸的位置，从以前的开发人员继承rails应用程序。我很高兴尝试学习ruby并分开旧代码来修复破坏的东西。我没有任何联系前开发人员的方法，除了在轨道上使用ruby之外，我对应用程序的了解也不多。我对.net环境比较熟悉，所以让RoR运行起来确实是一个挑战。

我只是尝试在本地克隆他们的代码库，并尝试在本地rails服务器上运行他们的代码。我能够克隆，我尝试的下一件事是运行捆绑安装，我得到了这个大块的文本，我无法做出正面或反面。

Make sure that `gem install libv8 -v '3.16.14.3'` succeeds before bundling.

对我来说，看起来libv8存在问题，但是还有一个关于没有安装python 2的警告，它也被添加到路径变量中。我应该添加我的开发环境是64位Windows 8.1。有人有这个工作吗？

谢谢。

Answer 1

你是正确的，libv8没有成功安装。

在该步骤成功之前，Bundler不会继续。你需要运行：

gem install libv8 -v '3.16.14.3'

Bundler的一个很好的功能是它为您提供了运行所需的命令以便继续。如果此命令失败，您应该收到更好的错误消息。

现有ruby应用程序的捆绑安装失败。我怀疑是libv8
