现有 ruby 应用的捆绑包安装失败。我怀疑libv8

Question

我很不幸地从以前的开发者那里继承了一个 rails 应用程序。我很高兴尝试学习 ruby 并拆解旧代码以修复损坏的部分。我没有任何联系前开发者的方式，除了它在 rails 上使用 ruby 外，我对该应用程序也知之甚少。我对 .net 环境更加熟悉，因此提高 RoR 和运行ning 被证明是一个挑战。

我只是想在本地克隆他们的代码库，然后尝试运行他们的代码在本地 rails 服务器上。我能够克隆，我尝试的下一件事是运行捆绑安装，我得到了一大块我无法理解的文本。

下面有大量文字

An error occurred while installing libv8 (3.16.14.3), and Bundler cannot continue.
Make sure that `gem install libv8 -v '3.16.14.3'` succeeds before bundling.

对我来说，libv8 似乎有问题，但也有关于 python 2 未安装的警告，但确实存在，并且已添加到路径变量中。我应该添加我的开发环境是 64 位 Windows 8.1。有没有人得到这个工作？

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。您需要运行:

gem install libv8 -v '3.16.14.3'

Bundler 的一个不错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，您应该会收到更好的错误消息。
