由于libv8，我无法运行“包安装”

Question

我正在Windows10上运行它。我正在尝试构建这个存储库(万一Gemfile和Gemfile.lock是有用的)：https://github.com/huginn/huginn

Error:

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

无论我在谷歌上做什么，最重要的答案总是一样的:我尝试了两种方法：

gem安装libv8 -v '3.16.14.1‘-系统-V8

或

gem安装libv8 -v '3.11.8.13‘-系统-V8

gem install libv8 --version '3.11.8.17' on ruby (windows)

libv8 required python 2 to be installed in order to build - Windows

therubyracer - Gem::Ext::BuildError: ERROR: Failed to build gem native extension

我看到Gemfile.lock有这个

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

因此，我假设Gemfile.lock会导致安装我不想要的版本。但我不知道怎么解决这个问题。

我仍然在学习Ruby，这是我第一个决定开始尝试的大型项目。

我的电脑上也有Python 2。所以我不知道为什么它说它不存在。

Answer 1

如果您查看Gemfile，它会声明，mini_racer创业板是一个可选的创业板，它是这里的症结所在，因此可能值得对其进行注释，并再次尝试捆绑。看看你有什么进展。

另外，如果mini_racer与therubyracer类似，在windows上并不真正需要，因为它内置了JScript，所以它不需要另一个javascript运行时。
