由于 libv8，我无法运行“捆绑安装”

Question

我在 Windows 10 上运行这个。我正在尝试构建这个存储库（如果 Gemfile 和 Gemfile.lock 有帮助）： https: //github.com/huginn/huginn

An error occurred while installing libv8 (7.3.492.27.1), and Bundler cannot

continue.

Make sure that `gem install libv8 -v '7.3.492.27.1' --source

'https://rubygems.org/'` succeeds before bundling.

In Gemfile:

mini_racer was resolved to 0.2.9, which depends on

libv8

无论我用谷歌搜索什么，最重要的答案总是相同的：我都尝试过：

gem install libv8 -v '3.16.14.1' -- --with-system-v8

或者

gem install libv8 -v '3.11.8.13' -- --with-system-v8

gem install libv8 --version '3.11.8.17' on ruby​​ (windows)
libv8 需要安装 python 2 才能构建 - Windows
therubyracer - Gem::Ext::BuildError: 错误: 无法构建 gem 本机扩展

我看到 Gemfile.lock 有这个

libv8 (7.3.492.27.1) 
..... 
mini_racer (0.2.9) 
  libv8 (>= 6.9.411)

所以我假设 Gemfile.lock 导致它安装我不想要的版本。但我不知道如何解决这个问题。

我仍在学习 Ruby，这是我决定开始尝试的第一个大项目。

我的电脑上也有 Python 2。所以我不确定为什么它说它不存在。

如果您查看 Gemfile，它会指出 mini_racer gem（这是这里的关键点）是一个可选 gem，因此可能值得将其注释掉并尝试再次捆绑。看看你是否能到达任何地方。

另外，如果 mini_racer 与 therubyracer 类似，则在 Windows 上并不真正需要，因为它内置了 JScript，因此它不需要另一个 javascript 运行时。
